General Precautions on Handling of Product
1. Treatment of NC Pins
Note: Do not connect anything to the NC pins.
The NC (not connected) pins are either not connected to any of the internal circuitry or are
used as test pins or to reduce noise. If something is connected to the NC pins, the
operation of the LSI is not guaranteed.
2. Treatment of Unused Input Pins
Note: Fix all unused input pins to high or low level.
Generally, the input pins of CMOS products are high-impedance input pins. If unused pins
are in their open states, intermediate levels are induced by noise in the vicinity, a passthrough current flows internally, and a malfunction may occur.
3. Processing before Initialization
Note: When power is first supplied, the product’s state is undefined.
The states of internal circuits are undefined until full power is supplied throughout the
chip and a low level is input on the reset pin. During the period where the states are
undefined, the register settings and the output state of each pin are also undefined. Design
your system so that it does not malfunction because of processing while it is in this
undefined state. For those products which have a reset function, reset the LSI immediately
after the power supply has been turned on.
4. Prohibition of Access to Undefined or Reserved Addresses
Note: Access to undefined or reserved addresses is prohibited.
The undefined or reserved addresses may be used to expand functions, or test registers
may have been be allocated to these addresses. Do not access these registers; the system’s
operation is not guaranteed if they are accessed.

Preface
The H8/36024 Group and H8/36014 Group are single-chip microcomputers made up of the highspeed H8/300H CPU employing Renesas Technology original architecture as their cores, and the
peripheral functions required to configure a system. The H8/300H CPU has an instruction set that
is compatible with the H8/300 CPU.
Target Users: This manual was written for users who will be using the H8/36024 Group and
H8/36014 Group in the design of application systems. Target users are expected to
understand the fundamentals of electrical circuits, logical circuits, and
microcomputers.
Objective:
This manual was written to explain the hardware functions and electrical
characteristics of the H8/36024 Group and H8/36014 Group to the target users.
Refer to the H8/300H Series Software Manual for a detailed description of the
instruction set.
Notes on reading this manual:
• In order to understand the overall functions of the chip
Read the manual according to the contents. This manual can be roughly categorized into parts
on the CPU, system control functions, peripheral functions and electrical characteristics.
• In order to understand the details of the CPU's functions
Read the H8/300H Series Software Manual.
• In order to understand the details of a register when its name is known
Read the index that is the final part of the manual to find the page number of the entry on the
register. The addresses, bits, and initial values of the registers are summarized in section 17,
List of Registers.
Example:
Bit order:
The MSB is on the left and the LSB is on the right.
Notes:
When using the on-chip emulator (E7, E8) for H8/36014 program development and debugging,
the following restrictions must be noted.
1. The NMI pin is reserved for the E7 or E8, and cannot be used.
2. Area H’7000 to H’7FFF is used by the E7 or E8, and is not available to the user.
3. Area H’F780 to H’FB7F must on no account be accessed.
Rev. 4.00 Sep. 23, 2005 Page vi of xxvi
4. When the E7 or E8 is used, address breaks can be set as either available to the user or for use
by the E7 or E8. If address breaks are set as being used by the E7 or E8, the address break
control registers must not be accessed.
5. When the E7 or E8 is used, NMI is an input/output pin (open-drain in output mode).
6. Use channel 1 of the SCI3 (P21/RXD, P22/TXD) in on-board programming mode by boot
mode.

2.2.1
General Registers
The H8/300H CPU has eight 32-bit general registers. These general registers are all functionally
identical and can be used as both address registers and data registers. When a general register is
used as a data register, it can be accessed as a 32-bit, 16-bit, or 8-bit register. Figure 2.3 illustrates
the usage of the general registers. When the general registers are used as 32-bit registers or address
registers, they are designated by the letters ER (ER0 to ER7).
The ER registers divide into 16-bit general registers designated by the letters E (E0 to E7) and R
(R0 to R7). These registers are functionally equivalent, providing a maximum of sixteen 16-bit
registers. The E registers (E0 to E7) are also referred to as extended registers.
The R registers divide into 8-bit registers designated by the letters RH (R0H to R7H) and RL (R0L
to R7L). These registers are functionally equivalent, providing a maximum of sixteen 8-bit
registers.
The usage of each register can be selected independently.

Figure 2.3 Usage of General Registers
General register ER7 has the function of stack pointer (SP) in addition to its general-register
function, and is used implicitly in exception handling and subroutine calls. Figure 2.4 shows the
stack.

2.2.2
Program Counter (PC)
This 24-bit counter indicates the address of the next instruction the CPU will execute. The length
of all CPU instructions is 2 bytes (one word), so the least significant PC bit is ignored. (When an
instruction is fetched, the least significant PC bit is regarded as 0). The PC is initialized when the
start address is loaded by the vector address generated during reset exception-handling sequence.
2.2.3
Condition-Code Register (CCR)
This 8-bit register contains internal CPU status information, including an interrupt mask bit (I) and
half-carry (H), negative (N), zero (Z), overflow (V), and carry (C) flags. The I bit is initialized to 1
by reset exception-handling sequence, but other bits are not initialized.
Some instructions leave flag bits unchanged. Operations can be performed on the CCR bits by the
LDC, STC, ANDC, ORC, and XORC instructions. The N, Z, V, and C flags are used as branching
conditions for conditional branch (Bcc) instructions.
For the action of each instruction on the flag bits, see Appendix A.1, Instruction List.

When the ADD.B, ADDX.B, SUB.B, SUBX.B, CMP.B,
or NEG.B instruction is executed, this flag is set to 1 if
there is a carry or borrow at bit 3, and cleared to 0
otherwise. When the ADD.W, SUB.W, CMP.W, or
NEG.W instruction is executed, the H flag is set to 1 if

Data Formats
The H8/300H CPU can process 1-bit, 4-bit (BCD), 8-bit (byte), 16-bit (word), and 32-bit
(longword) data. Bit-manipulation instructions operate on 1-bit data by accessing bit n (n = 0, 1, 2,
…, 7) of byte operand data. The DAA and DAS decimal-adjust instructions treat byte data as two
digits of 4-bit BCD data.

Memory Data Formats
Figure 2.6 shows the data formats in memory. The H8/300H CPU can access word data and
longword data in memory, however word or longword data must begin at an even address. If an
attempt is made to access word or longword data at an odd address, an address error does not
occur, however the least significant bit of the address is regarded as 0, so access begins the
preceding address. This also applies to instruction fetches.
When ER7 (SP) is used as an address register to access the stack, the operand size should be word
or longword.

Basic Instruction Formats
H8/300H CPU instructions consist of 2-byte (1-word) units. An instruction consists of an
operation field (op field), a register field (r field), an effective address extension (EA field), and a
condition field (cc).
Figure 2.7 shows examples of instruction formats.
• Operation Field
Indicates the function of the instruction, the addressing mode, and the operation to be carried
out on the operand. The operation field always includes the first four bits of the instruction.
Some instructions have two operation fields.
• Register Field
Specifies a general register. Address registers are specified by 3 bits, and data registers by 3
bits or 4 bits. Some instructions have two register fields. Some have no register field.
• Effective Address Extension
8, 16, or 32 bits specifying immediate data, an absolute address, or a displacement. A24-bit
address or displacement is treated as a 32-bit data in which the first 8 bits are 0 (H'00).
• Condition Field
Specifies the branching condition of Bcc instructions.

Addressing Modes and Effective Address Calculation
The following describes the H8/300H CPU. In this LSI, the upper eight bits are ignored in the
generated 24-bit address, so the effective address is 16 bits.
2.5.1
Addressing Modes
The H8/300H CPU supports the eight addressing modes listed in table 2.10. Each instruction uses
a subset of these addressing modes. Addressing modes that can be used differ depending on the
instruction. For details, refer to Appendix A.4, Combinations of Instructions and Addressing
Modes.
Arithmetic and logic instructions can use the register direct and immediate modes. Data transfer
instructions can use all addressing modes except program-counter relative and memory indirect.
Bit manipulation instructions use register direct, register indirect, or the absolute addressing mode
to specify an operand, and register direct (BSET, BCLR, BNOT, and BTST instructions) or
immediate (3-bit) addressing mode to specify a bit number in the operand.

REJ09B0025-0400
Section 2 CPU
(1)
Register Direct—Rn
The register field of the instruction specifies an 8-, 16-, or 32-bit general register containing the
operand. R0H to R7H and R0L to R7L can be specified as 8-bit registers. R0 to R7 and E0 to E7
can be specified as 16-bit registers. ER0 to ER7 can be specified as 32-bit registers.
(2)
Register Indirect—@ERn
The register field of the instruction code specifies an address register (ERn), the lower 24 bits of
which contain the address of the operand on memory.
(3)
Register Indirect with Displacement—@(d:16, ERn) or @(d:24, ERn)
A 16-bit or 24-bit displacement contained in the instruction is added to an address register (ERn)
specified by the register field of the instruction, and the lower 24 bits of the sum the address of a
memory operand. A 16-bit displacement is sign-extended when added.
(4)
Register Indirect with Post-Increment or Pre-Decrement—@ERn+ or @-ERn
• Register indirect with post-increment—@ERn+
The register field of the instruction code specifies an address register (ERn) the lower 24 bits
of which contains the address of a memory operand. After the operand is accessed, 1, 2, or 4 is
added to the address register contents (32 bits) and the sum is stored in the address register.
The value added is 1 for byte access, 2 for word access, or 4 for longword access. For the word
or longword access, the register value should be even.
• Register indirect with pre-decrement—@-ERn
The value 1, 2, or 4 is subtracted from an address register (ERn) specified by the register field
in the instruction code, and the lower 24 bits of the result is the address of a memory operand.
The result is also stored in the address register. The value subtracted is 1 for byte access, 2 for
word access, or 4 for longword access. For the word or longword access, the register value
should be even.
(5)
Absolute Address—@aa:8, @aa:16, @aa:24
The instruction code contains the absolute address of a memory operand. The absolute address
may be 8 bits long (@aa:8), 16 bits long (@aa:16), 24 bits long (@aa:24)
For an 8-bit absolute address, the upper 16 bits are all assumed to be 1 (H'FFFF). For a 16-bit
absolute address the upper 8 bits are a sign extension. A 24-bit absolute address can access the
entire address space.
Rev. 4.00 Sep. 23, 2005 Page 31 of 354
REJ09B0025-0400
Section 2 CPU
The access ranges of absolute addresses for the group of this LSI are those shown in table 2.11,
because the upper 8 bits are ignored.
Table 2.11 Absolute Address Access Ranges
Absolute Address
Access Range
8 bits (@aa:8)
H'FF00 to H'FFFF
16 bits (@aa:16)
H'0000 to H'FFFF
24 bits (@aa:24)
H'0000 to H'FFFF
(6)
Immediate—#xx:8, #xx:16, or #xx:32
The instruction contains 8-bit (#xx:8), 16-bit (#xx:16), or 32-bit (#xx:32) immediate data as an
operand.
The ADDS, SUBS, INC, and DEC instructions contain immediate data implicitly. Some bit
manipulation instructions contain 3-bit immediate data in the instruction code, specifying a bit
number. The TRAPA instruction contains 2-bit immediate data in its instruction code, specifying a
vector address.
(7)
Program-Counter Relative—@(d:8, PC) or @(d:16, PC)
This mode is used in the BSR instruction. An 8-bit or 16-bit displacement contained in the
instruction is sign-extended and added to the 24-bit PC contents to generate a branch address. The
PC value to which the displacement is added is the address of the first byte of the next instruction,
so the possible branching range is –126 to +128 bytes (–63 to +64 words) or –32766 to +32768
bytes (–16383 to +16384 words) from the branch instruction. The resulting value should be an
even number.
(8)
Memory Indirect—@@aa:8
This mode can be used by the JMP and JSR instructions. The instruction code contains an 8-bit
absolute address specifying a memory operand. This memory operand contains a branch address.
The memory operand is accessed by longword access. The first byte of the memory operand is
ignored, generating a 24-bit branch address. Figure 2.8 shows how to specify branch address for in
memory indirect mode. The upper bits of the absolute address are all assumed to be 0, so the
address range is 0 to 255 (H'0000 to H'00FF).
Note that the first part of the address range is also the exception vector area.

Basic Bus Cycle
CPU operation is synchronized by a system clock (φ) or a subclock (φSUB). The period from a rising
edge of φ or φSUB to the next rising edge is called one state. A bus cycle consists of two states or
three states. The cycle differs depending on whether access is to on-chip memory or to on-chip
peripheral modules.
2.6.1
Access to On-Chip Memory (RAM, ROM)
Access to on-chip memory takes place in two states. The data bus width is 16 bits, allowing access
in byte or word size. Figure 2.9 shows the on-chip memory access cycle.

Section 2 CPU
2.6.2
On-Chip Peripheral Modules
On-chip peripheral modules are accessed in two states or three states. The data bus width is 8 bits
or 16 bits depending on the register. For description on the data bus width and number of
accessing states of each register, refer to section 17.1, Register Addresses (Address Order).
Registers with 16-bit data bus width can be accessed by word size only. Registers with 8-bit data
bus width can be accessed by byte or word size. When a register with 8-bit data bus width is
accessed by word size, a bus cycle occurs twice. In two-state access, the operation timing is the
same as that for on-chip memory.
Figure 2.10 shows the operation timing in the case of three-state access to an on-chip peripheral
module.

CPU States
There are four CPU states: the reset state, program execution state, program halt state, and
exception-handling state. The program execution state includes active mode. In the program halt
state there are a sleep mode, and standby mode. These states are shown in figure 2.11. Figure 2.12
shows the state transitions. For details on program execution state and program halt state, refer to
section 6, Power-Down Modes. For details on exception processing, refer to section 3, Exception
Handling.

Usage Notes
2.8.1
Notes on Data Access to Empty Areas
The address space of this LSI includes empty areas in addition to the ROM, RAM, and on-chip
I/O registers areas available to the user. When data is transferred from CPU to empty areas, the
transferred data will be lost. This action may also cause the CPU to malfunction. When data is
transferred from an empty area to CPU, the contents of the data cannot be guaranteed.
2.8.2
EEPMOV Instruction
EEPMOV is a block-transfer instruction and transfers the byte size of data indicated by R4L,
which starts from the address indicated by R5, to the address indicated by R6. Set R4L and R6 so
that the end address of the destination address (value of R6 + R4L) does not exceed H'FFFF (the
value of R6 must not change from H'FFFF to H'0000 during execution).
2.8.3
Bit Manipulation Instruction
The BSET, BCLR, BNOT, BST, and BIST instructions read data from the specified address in
byte units, manipulate the data of the target bit, and write data to the same address again in byte
units. Special care is required when using these instructions in cases where two registers are
assigned to the same address or when a bit is directly manipulated for a port, because this may
rewrite data of a bit other than the bit to be manipulated.

Bit manipulation for two registers assigned to the same address
Example: Bit manipulation for the timer load register and timer counter
(Applicable for timer B and timer C, not for the group of this LSI.)
Figure 2.13 shows an example of a timer in which two timer registers are assigned to the same
address. When a bit manipulation instruction accesses the timer load register and timer counter of
a reloadable timer, since these two registers share the same address, the following operations takes
place.
1. Data is read in byte units.
2. The CPU sets or resets the bit to be manipulated with the bit manipulation instruction.
3. The written data is written again in byte units to the timer load register.
The timer is counting, so the value read is not necessarily the same as the value in the timer load
register. As a result, bits other than the intended bit in the timer counter may be modified and the
modified value may be written to the timer load register.

P57 and P56 are input pins, with a low-level signal input at P57 and a high-level signal input at
P56. P55 to P50 are output pins and output low-level signals. An example to output a high-level

• Description on operation
1. When the BSET instruction is executed, first the CPU reads port 5.
Since P57 and P56 are input pins, the CPU reads the pin states (low-level and high-level
input).
P55 to P50 are output pins, so the CPU reads the value in PDR5. In this example PDR5 has a
value of H'80, but the value read by the CPU is H'40.
2. Next, the CPU sets bit 0 of the read data to 1, changing the PDR5 data to H'41.
3. Finally, the CPU writes H'41 to PDR5, completing execution of BSET.
Rev. 4.00 Sep. 23, 2005 Page 40 of 354
REJ09B0025-0400
Section 2 CPU
As a result of the BSET instruction, bit 0 in PDR5 becomes 1, and P50 outputs a high-level
signal. However, bits 7 and 6 of PDR5 end up with different values. To prevent this problem,
store a copy of the PDR5 data in a work area in memory. Perform the bit manipulation on the
data in the work area, then write this data to PDR5.

Bit Manipulation in a Register Containing a Write-Only Bit
Example 3: BCLR instruction executed designating port 5 control register PCR5
P57 and P56 are input pins, with a low-level signal input at P57 and a high-level signal input at
P56. P55 to P50 are output pins that output low-level signals. An example of setting the P50 pin as
an input pin by the BCLR instruction is shown below. It is assumed that a high-level signal will be
input to this input pin.

• Description on operation
1. When the BCLR instruction is executed, first the CPU reads PCR5. Since PCR5 is a write-only
register, the CPU reads a value of H'FF, even though the PCR5 value is actually H'3F.
2. Next, the CPU clears bit 0 in the read data to 0, changing the data to H'FE.
3. Finally, H'FE is written to PCR5 and BCLR instruction execution ends.
As a result of this operation, bit 0 in PCR5 becomes 0, making P50 an input port. However,
bits 7 and 6 in PCR5 change to 1, so that P57 and P56 change from input pins to output pins.
To prevent this problem, store a copy of the PCR5 data in a work area in memory and
manipulate data of the bit in the work area, then write this data to PCR5.

Section 3 Exception Handling
Section 3 Exception Handling
Exception handling may be caused by a reset, a trap instruction (TRAPA), or interrupts.
• Reset
A reset has the highest exception priority. Exception handling starts as soon as the reset is cleared
by the RES pin. The chip is also reset when the watchdog timer overflows, and exception handling
starts. Exception handling is the same as exception handling by the RES pin.
• Trap Instruction
Exception handling starts when a trap instruction (TRAPA) is executed. The TRAPA instruction
generates a vector address corresponding to a vector number from 0 to 3, as specified in the
instruction code. Exception handling can be executed at all times in the program execution state.
• Interrupts
External interrupts other than NMI and internal interrupts other than address break are masked by
the I bit in CCR, and kept masked while the I bit is set to 1. Exception handling starts when the
current instruction or exception handling ends, if an interrupt request has been issued.
3.1
Exception Sources and Vector Address
Table 3.1 shows the vector addresses and priority of each exception handling. When more than
one interrupt is requested, handling is performed from the interrupt with the highest priority.

When this bit is set to 1, interrupt requests of the IRQ0 pin

When disabling interrupts by clearing bits in an interrupt enable register, or when clearing bits in
an interrupt flag register, always do so while interrupts are masked (I = 1). If the above clear
operations are performed while I = 0, and as a result a conflict arises between the clear instruction
and an interrupt request, exception handling for the interrupt will be executed after the clear
instruction has been executed.

Reset Exception Handling
When the RES pin goes low, all processing halts and this LSI enters the reset. The internal state of
the CPU and the registers of the on-chip peripheral modules are initialized by the reset. To ensure
that this LSI is reset at power-up, hold the RES pin low until the clock pulse generator output
stabilizes. To reset the chip during operation, hold the RES pin low for at least 10 system clock
cycles. When the RES pin goes high after being held low for the necessary time, this LSI starts
reset exception handling. The reset exception handling sequence is shown in figure 3.1.
The reset exception handling sequence is as follows. However, for the reset exception handling
sequence of the product with on-chip power-on reset circuit, refer to section 15, Power-On Reset
and Low-Voltage Detection Circuits (Optional).
1. Set the I bit in the condition code register (CCR) to 1.
2. The CPU generates a reset exception handling vector address (from H'0000 to H'0001), the
data in that address is sent to the program counter (PC) as the start address, and program
execution starts from that address.

Interrupt Exception Handling
3.4.1
External Interrupts
There are external interrupts, NMI, IRQ3, IRQ0, and WKP.
(1)
NMI
NMI interrupt is requested by input falling edge to pin NMI.
NMI is the highest interrupt, and can always be accepted without depending on the I bit value in
CCR.
(2)
IRQ3 to IRQ0 Interrupts
IRQ3 to IRQ0 interrupts are requested by input signals to pins IRQ3 to IRQ0. These four
interrupts are given different vector addresses, and are detected individually by either rising edge
sensing or falling edge sensing, depending on the settings of bits IEG3 to IEG0 in IEGR1.
When pins IRQ3 to IRQ0 are designated for interrupt input in PMR1 and the designated signal
edge is input, the corresponding bit in IRR1 is set to 1, requesting the CPU of an interrupt. When
IRQ3 to IRQ0 interrupt is accepted, the I bit is set to 1 in CCR. These interrupts can be masked by
setting bits IEN3 to IEN0 in IENR1.
(3)
WKP5 to WKP0 Interrupts
WKP5 to WKP0 interrupts are requested by input signals to pins WKP5 to WKP0. These six
interrupts have the same vector addresses, and are detected individually by either rising edge
sensing or falling edge sensing, depending on the settings of bits WPEG5 to WPEG0 in IEGR2.
When pins WKP5 to WKP0 are designated for interrupt input in PMR5 and the designated signal
edge is input, the corresponding bit in IWPR is set to 1, requesting the CPU of an interrupt. These
interrupts can be masked by setting bit IENWP in IENR1.

Internal Interrupts
Each on-chip peripheral module has a flag to show the interrupt request status and the enable bit to
enable or disable the interrupt. For direct transfer interrupt requests generated by execution of a
SLEEP instruction, this function is included in IRR1 and IENR1.
When an on-chip peripheral module requests an interrupt, the corresponding interrupt request
status flag is set to 1, requesting the CPU of an interrupt. When this interrupt is accepted, the I bit
is set to 1 in CCR. These interrupts can be masked by writing 0 to clear the corresponding enable
bit.

REJ09B0025-0400
Section 3 Exception Handling
3.4.3
Interrupt Handling Sequence
Interrupts are controlled by an interrupt controller.
Interrupt operation is described as follows.
1. If an interrupt occurs while the NMI or interrupt enable bit is set to 1, an interrupt request
signal is sent to the interrupt controller.
2. When multiple interrupt requests are generated, the interrupt controller requests to the CPU for
the interrupt handling with the highest priority at that time according to table 3.1. Other
interrupt requests are held pending.
3. The CPU accepts the NMI or address break without depending on the I bit value. Other
interrupt requests are accepted, if the I bit is cleared to 0 in CCR; if the I bit is set to 1, the
interrupt request is held pending.
4. If the CPU accepts the interrupt after processing of the current instruction is completed,
interrupt exception handling will begin. First, both PC and CCR are pushed onto the stack. The
state of the stack at this time is shown in figure 3.2. The PC value pushed onto the stack is the
address of the first instruction to be executed upon return from interrupt handling.
5. Then, the I bit of CCR is set to 1, masking further interrupts excluding the NMI and address
break. Upon return from interrupt handling, the values of I bit and other bits in CCR will be
restored and returned to the values prior to the start of interrupt exception handling.
6. Next, the CPU generates the vector address corresponding to the accepted interrupt, and
transfers the address to PC as a start address of the interrupt handling-routine. Then a program
starts executing from the address indicated in PC.
Figure 3.3 shows a typical interrupt sequence where the program area is in the on-chip ROM and
the stack area is in the on-chip RAM.

Usage Notes
3.5.1
Interrupts after Reset
If an interrupt is accepted after a reset and before the stack pointer (SP) is initialized, the PC and
CCR will not be saved correctly, leading to a program crash. To prevent this, all interrupt requests,
including NMI, are disabled immediately after a reset. Since the first instruction of a program is
always executed immediately after the reset state ends, make sure that this instruction initializes
the stack pointer (example: MOV.W #xx: 16, SP).
3.5.2
Notes on Stack Area Use
When word data is accessed, the least significant bit of the address is regarded as 0. Access to the
stack always takes place in word size, so the stack pointer (SP: R7) should never indicate an odd
address. Use PUSH Rn (MOV.W Rn, @–SP) or POP Rn (MOV.W @SP+, Rn) to save or restore
register values.
3.5.3
Notes on Rewriting Port Mode Registers
When a port mode register is rewritten to switch the functions of external interrupt pins, IRQ3,
IRQ0, and WKP5 to WKP0, the interrupt request flag may be set to 1.
Figure 3.4 shows a port mode register setting and interrupt request flag clearing procedure.
When switching a pin function, mask the interrupt before setting the bit in the port mode register.
After accessing the port mode register, execute at least one instruction (e.g., NOP), then clear the
interrupt request flag from 1 to 0.
CCR I bit ← 1
Interrupts masked. (Another possibility
is to disable the relevant interrupt in
interrupt enable register 1.)

After setting the port mode register bit,
first execute at least one instruction

request flag to 0

Section 4 Address Break
Section 4 Address Break
The address break simplifies on-board program debugging. It requests an address break interrupt
when the set break condition is satisfied. The interrupt request is not affected by the I bit of CCR.
Break conditions that can be set include instruction execution at a specific address and a
combination of access and data at a specific address. With the address break function, the
execution start point of a program containing a bug is detected and execution is branched to the
correcting program. Figure 4.1 shows a block diagram of the address break.

Section 4 Address Break
4.1.3
Break Address Registers (BARH, BARL)
BARH and BARL are 16-bit read/write registers that set the address for generating an address
break interrupt. When setting the address break condition to the instruction execution cycle, set
the first byte address of the instruction. The initial value of this register is H'FFFF.
4.1.4
Break Data Registers (BDRH, BDRL)
BDRH and BDRL are 16-bit read/write registers that set the data for generating an address break
interrupt. BDRH is compared with the upper 8-bit data bus. BDRL is compared with the lower 8bit data bus. When memory or registers are accessed by byte, the upper 8-bit data bus is used for
even and odd addresses in the data transmission. Therefore, comparison data must be set in
BDRH for byte access. For word access, the data bus used depends on the address. See section
4.1.1, Address Break Control Register (ABRKCR), for details. The initial value of this register is
undefined.
4.2
Operation
When the ABIF and ABIE bits in ABRKSR are set to 1, the address break function generates an
interrupt request to the CPU. The ABIF bit in ABRKSR is set to 1 by the combination of the
address set in BAR, the data set in BDR, and the conditions set in ABRKCR. When the interrupt
request is accepted, interrupt exception handling starts after the instruction being executed ends.
The address break interrupt is not masked because of the I bit in CCR of the CPU.

Prescalers

Prescaler S
Prescaler S is a 13-bit counter using the system clock (φ) as its input clock. It is incremented once
per clock period. Prescaler S is initialized to H'0000 by a reset, and starts counting on exit from
the reset state. In standby mode and subsleep mode, the system clock pulse generator stops.
Prescaler S also stops and is initialized to H'0000. The CPU cannot read or write prescaler S.
The output from prescaler S is shared by the on-chip peripheral modules. The divider ratio can be
set separately for each on-chip peripheral function. In active mode and sleep mode, the clock input
to prescaler S is determined by the division factor designated by MA2 to MA0 in SYSCR2.

Note on Resonators
Resonator characteristics are closely related to board design and should be carefully evaluated by
the user, referring to the examples shown in this section. Resonator circuit constants will differ
depending on the resonator element, stray capacitance in its interconnecting circuit, and other
factors. Suitable constants should be determined in consultation with the resonator element
manufacturer. Design the circuit so that the resonator element never receives voltages exceeding
its maximum rating.

close as possible to the OSC1 and OSC2 pins. Other signal lines should be routed away from the
oscillator circuit to prevent induction from interfering with correct oscillation (see figure 5.7).

Section 6 Power-Down Modes
Section 6 Power-Down Modes
This LSI has five modes of operation after a reset. These include a normal active mode and three
power-down modes, in which power consumption is significantly reduced. Module standby mode
reduces power consumption by selectively halting on-chip module functions.
• Active mode
The CPU and all on-chip peripheral modules are operable on the system clock. The system
clock frequency can be selected from φosc, φosc/8, φosc/16, φosc/32, and φosc/64.
• Sleep mode
The CPU halts. On-chip peripheral modules are operable on the system clock.
• Standby mode
The CPU and all on-chip peripheral modules halt.
• Subsleep mode
The CPU and all on-chip peripheral modules halt. I/O ports keep the same states as before the
transition.
• Module standby mode
Independent of the above modes, power consumption can be reduced by halting on-chip
peripheral modules that are not used in module units.

Mode Transitions and States of LSI
Figure 6.1 shows the possible transitions among these operating modes. A transition is made from
the program execution state to the program halt state of the program by executing a SLEEP
instruction. Interrupts allow for returning from the program halt state to the program execution
state of the program. A direct transition from active mode to active mode changes the operating
frequency. RES input enables transitions from a mode to the reset state. Table 6.2 shows the
transition conditions of each mode after the SLEEP instruction is executed and a mode to return
by an interrupt. Table 6.3 shows the internal states of the LSI in each mode.

Section 6 Power-Down Modes
6.2.1
Sleep Mode
In sleep mode, CPU operation is halted but the on-chip peripheral modules function at the clock
frequency set by the MA2 to MA0 bits in SYSCR2. CPU register contents are retained. When an
interrupt is requested, sleep mode is cleared and interrupt exception handling starts. Sleep mode is
not cleared if the I bit of the condition code register (CCR) is set to 1 or the requested interrupt is
disabled in the interrupt enable register. a transition is made to subactive mode when the bit is 1.
When the RES pin goes low, the CPU goes into the reset state and sleep mode is cleared.
6.2.2
Standby Mode
In standby mode, the clock pulse generator stops, so the CPU and on-chip peripheral modules stop
functioning. However, as long as the rated voltage is supplied, the contents of CPU registers, onchip RAM, and some on-chip peripheral module registers are retained. On-chip RAM contents
will be retained as long as the voltage set by the RAM data retention voltage is provided. The I/O
ports go to the high-impedance state.
Standby mode is cleared by an interrupt. When an interrupt is requested, the system clock pulse
generator starts. After the time set in bits STS2–STS0 in SYSCR1 has elapsed, and interrupt
exception handling starts. Standby mode is not cleared if the I bit of CCR is set to 1 or the
requested interrupt is disabled in the interrupt enable register.
When the RES pin goes low, the system clock pulse generator starts. Since system clock signals
are supplied to the entire chip as soon as the system clock pulse generator starts functioning, the
RES pin must be kept low until the pulse generator output stabilizes. After the pulse generator
output has stabilized, the CPU starts reset exception handling if the RES pin is driven high.
6.2.3
Subsleep Mode
In subsleep mode, the system clock oscillator is halted, and operation of the CPU and on-chip
peripheral modules is halted. As long as a required voltage is applied, the contents of CPU
registers, the on-chip RAM, and some registers of the on-chip peripheral modules are retained. I/O
ports keep the same states as before the transition.
Subsleep mode is cleared by an interrupt. When an interrupt is requested, the system clock
oscillator starts to oscillate. Subsleep mode is cleared and an interrupt exception handling starts
when the time set in bits STS2 to STS0 in SYSCR1 elapses. Subsleep mode is not cleared if the I
bit of CCR is 1 or the interrupt is disabled in the interrupt enable bit.
Rev. 4.00 Sep. 23, 2005 Page 75 of 354
REJ09B0025-0400
Section 6 Power-Down Modes
6.3
Operating Frequency in Active Mode
Operation in active mode is clocked at the frequency designated by the MA2 to MA0 bits in
SYSCR2. The operating frequency changes to the set frequency after SLEEP instruction
execution.
6.4
Direct Transition
The CPU can execute programs in active mode. The operating frequency can be changed by
making a transition directly from active mode to active mode. A direct transition can be made by
executing a SLEEP instruction while the DTON bit in SYSCR2 is set to 1. The direct transition
also enables operating frequency modification in active mode. After the mode transition, direct
transition interrupt exception handling starts.
If the direct transition interrupt is disabled in interrupt enable register 1, a transition is made
instead to sleep mode. Note that if a direct transition is attempted while the I bit in CCR is set to 1,
sleep mode will be entered, and the resulting mode cannot be cleared by means of an interrupt.
6.5
Module Standby Function
The module-standby function can be set to any peripheral module. In module standby mode, the
clock supply to modules stops to enter the power-down mode. Module standby mode enables each
on-chip peripheral module to enter the standby state by setting a bit that corresponds to each
module in MSTCR1 and MSTCR2 to 1 and cancels the mode by clearing the bit to 0.

The features of the 32-kbyte (4 kbytes of them are the control program area for E7 or E8) flash
memory built into the HD64F36024 and HD64F36014 are summarized below.
• Programming/erase methods
 The flash memory is programmed 128 bytes at a time. Erase is performed in single-block
units. The flash memory is configured as follows: 1 kbyte × 4 blocks and 28 kbytes × 1
block. To erase the entire flash memory, each block must be erased in turn.
• Reprogramming capability
 The flash memory can be reprogrammed up to 1,000 times.
• On-board programming
 On-board programming/erasing can be done in boot mode, in which the boot program built
into the chip is started to erase or program of the entire flash memory. In normal user
program mode, individual blocks can be erased or programmed.
• Automatic bit rate adjustment
 For data transfer in boot mode, this LSI's bit rate can be automatically adjusted to match
the transfer bit rate of the host.
• Programming/erasing protection
 Sets software protection against flash memory programming/erasing.

7.3
On-Board Programming Modes
There is a mode for programming/erasing of the flash memory; boot mode, which enables onboard programming/erasing. On-board programming/erasing can also be performed in user
program mode. At reset-start in reset mode, this LSI changes to a mode depending on the TEST
pin settings, NMI pin settings, and input level of each port, as shown in table 7.1. The input level
of each pin must be defined four states before the reset ends.
When changing to boot mode, the boot program built into this LSI is initiated. The boot program
transfers the programming control program from the externally-connected host to on-chip RAM
via SCI3. After erasing the entire flash memory, the programming control program is executed.
This can be used for programming initial values in the on-board state or for a forcible return when
programming/erasing can no longer be done in user program mode. In user program mode,
individual blocks can be erased and programmed by branching to the user program/erase control
program prepared by the user.

Boot Mode
Table 7.2 shows the boot mode operations between reset end and branching to the programming
control program.
1. When boot mode is used, the flash memory programming control program must be prepared in
the host beforehand. Prepare a programming control program in accordance with the
description in section 7.4, Flash Memory Programming/Erasing.
2. SCI3 should be set to asynchronous mode, and the transfer format as follows: 8-bit data, 1 stop
bit, and no parity.
3. When the boot program is initiated, the chip measures the low-level period of asynchronous
SCI communication data (H'00) transmitted continuously from the host. The chip then
calculates the bit rate of transmission from the host, and adjusts the SCI3 bit rate to match that
of the host. The reset should end with the RxD pin high. The RxD and TxD pins should be
pulled up on the board if necessary. After the reset is complete, it takes approximately 100
states before the chip is ready to measure the low-level period.
Rev. 4.00 Sep. 23, 2005 Page 82 of 354
REJ09B0025-0400
Section 7 ROM
4. After matching the bit rates, the chip transmits one H'00 byte to the host to indicate the
completion of bit rate adjustment. The host should confirm that this adjustment end indication
(H'00) has been received normally, and transmit one H'55 byte to the chip. If reception could
not be performed normally, initiate boot mode again by a reset. Depending on the host's
transfer bit rate and system clock frequency of this LSI, there will be a discrepancy between
the bit rates of the host and the chip. To operate the SCI properly, set the host's transfer bit rate
and system clock frequency of this LSI within the ranges listed in table 7.3.
5. In boot mode, a part of the on-chip RAM area is used by the boot program. The area H'F780 to
H'FEEF is the area to which the programming control program is transferred from the host.
The boot program area cannot be used until the execution state in boot mode switches to the
programming control program.
6. Before branching to the programming control program, the chip terminates transfer operations
by SCI3 (by clearing the RE and TE bits in SCR3 to 0), however the adjusted bit rate value
remains set in BRR. Therefore, the programming control program can still use it for transfer of
write data or verify data with the host. The TxD pin is high (PCR22 = 1, P22 = 1). The
contents of the CPU general registers are undefined immediately after branching to the
programming control program. These registers must be initialized at the beginning of the
programming control program, as the stack pointer (SP), in particular, is used implicitly in
subroutine calls, etc.
7. Boot mode can be cleared by a reset. End the reset after driving the reset pin low, waiting at
least 20 states, and then setting the NMI pin. Boot mode is also cleared when a WDT overflow
occurs.
8. Do not change the TEST pin and NMI pin input levels in boot mode.

Programming/Erasing in User Program Mode
On-board programming/erasing of an individual flash memory block can also be performed in user
program mode by branching to a user program/erase control program. The user must set branching
conditions and provide on-board means of supplying programming data. The flash memory must
contain the user program/erase control program or a program that provides the user program/erase
control program from external memory. As the flash memory itself cannot be read during
programming/erasing, transfer the user program/erase control program to on-chip RAM, as in boot
mode. Figure 7.2 shows a sample procedure for programming/erasing in user program mode.

7.4
Flash Memory Programming/Erasing
A software method using the CPU is employed to program and erase flash memory in the onboard programming modes. Depending on the FLMCR1 setting, the flash memory operates in one
of the following four modes: Program mode, program-verify mode, erase mode, and erase-verify
mode. The programming control program in boot mode and the user program/erase control
program in user program mode use these operating modes in combination to perform
programming/erasing. Flash memory programming and erasing should be performed in
accordance with the descriptions in section 7.4.1, Program/Program-Verify and section 7.4.2,
Erase/Erase-Verify, respectively.
7.4.1
Program/Program-Verify
When writing data or programs to the flash memory, the program/program-verify flowchart shown
in figure 7.3 should be followed. Performing programming operations according to this flowchart
will enable data or programs to be written to the flash memory without subjecting the chip to
voltage stress or sacrificing program data reliability.
1. Programming must be done to an empty address. Do not reprogram an address to which
programming has already been performed.
2. Programming should be carried out 128 bytes at a time. A 128-byte data transfer must be
performed even if writing fewer than 128 bytes. In this case, H'FF data must be written to the
extra addresses.
3. Prepare the following data storage areas in RAM: A 128-byte programming data area, a 128byte reprogramming data area, and a 128-byte additional-programming data area. Perform
reprogramming data computation according to table 7.4, and additional programming data
computation according to table 7.5.
4. Consecutively transfer 128 bytes of data in byte units from the reprogramming data area or
additional-programming data area to the flash memory. The program address and 128-byte
data are latched in the flash memory. The lower 8 bits of the start address in the flash memory
destination area must be H'00 or H'80.
5. The time during which the P bit is set to 1 is the programming time. Table 7.6 shows the
allowable programming times.
6. The watchdog timer (WDT) is set to prevent overprogramming due to program runaway, etc.
An overflow cycle of approximately 6.6 ms is allowed.
7. For a dummy write to a verify address, write 1-byte data H'FF to an address whose lower 2
bits are B'00. Verify data can be read in words or in longwords from the address to which a
dummy write was performed.

Erase/Erase-Verify
When erasing flash memory, the erase/erase-verify flowchart shown in figure 7.4 should be
followed.
1. Prewriting (setting erase block data to all 0s) is not necessary.
2. Erasing is performed in block units. Make only a single-bit specification in the erase block
register (EBR1). To erase multiple blocks, each block must be erased in turn.
3. The time during which the E bit is set to 1 is the flash memory erase time.
4. The watchdog timer (WDT) is set to prevent overerasing due to program runaway, etc. An
overflow cycle of approximately 19.8 ms is allowed.
Rev. 4.00 Sep. 23, 2005 Page 88 of 354

Section 7 ROM
5. For a dummy write to a verify address, write 1-byte data H'FF to an address whose lower two
bits are B'00. Verify data can be read in longwords from the address to which a dummy write
was performed.
6. If the read data is not erased successfully, set erase mode again, and repeat the erase/eraseverify sequence as before. The maximum number of repetitions of the erase/erase-verify
sequence is 100.
7.4.3
Interrupt Handling when Programming/Erasing Flash Memory
All interrupts, including the NMI interrupt, are disabled while flash memory is being programmed
or erased, or while the boot program is executing, for the following three reasons:
1. Interrupt during programming/erasing may cause a violation of the programming or erasing
algorithm, with the result that normal operation cannot be assured.
2. If interrupt exception handling starts before the vector address is written or during
programming/erasing, a correct vector cannot be fetched and the CPU malfunctions.
3. If an interrupt occurs during boot program execution, normal boot mode sequence cannot be
carried out.

Section 7 ROM
7.5
Program/Erase Protection
There are three kinds of flash memory program/erase protection; hardware protection, software
protection, and error protection.
7.5.1
Hardware Protection
Hardware protection refers to a state in which programming/erasing of flash memory is forcibly
disabled or aborted because of a transition to reset, subsleep mode or standby mode. Flash
memory control register 1 (FLMCR1), flash memory control register 2 (FLMCR2), and erase
block register 1 (EBR1) are initialized. In a reset via the RES pin, the reset state is not entered
unless the RES pin is held low until oscillation stabilizes after powering on. In the case of a reset
during operation, hold the RES pin low for the RES pulse width specified in the AC
Characteristics section.
7.5.2
Software Protection
Software protection can be implemented against programming/erasing of all flash memory blocks
by clearing the SWE bit in FLMCR1. When software protection is in effect, setting the P or E bit
in FLMCR1 does not cause a transition to program mode or erase mode. By setting the erase block
register 1 (EBR1), erase protection can be set for individual blocks. When EBR1 is set to H'00,
erase protection is set for all blocks.
7.5.3
Error Protection
In error protection, an error is detected when CPU runaway occurs during flash memory
programming/erasing, or operation is not performed in accordance with the program/erase
algorithm, and the program/erase operation is aborted. Aborting the program/erase operation
prevents damage to the flash memory due to overprogramming or overerasing.
When the following errors are detected during programming/erasing of flash memory, the FLER
bit in FLMCR2 is set to 1, and the error protection state is entered.
• When the flash memory of the relevant address area is read during programming/erasing
(including vector read and instruction fetch)
• Immediately after exception handling excluding a reset during programming/erasing
• When a SLEEP instruction is executed during programming/erasing
Rev. 4.00 Sep. 23, 2005 Page 91 of 354
REJ09B0025-0400
Section 7 ROM
The FLMCR1, FLMCR2, and EBR1 settings are retained, however program mode or erase mode
is aborted at the point at which the error occurred. Program mode or erase mode cannot be reentered by re-setting the P or E bit. However, PV and EV bit setting is enabled, and a transition
can be made to verify mode. Error protection can be cleared only by a reset.

Section 9 I/O Ports
The group of this LSI has thirty general I/O ports and four general input-only ports. Port 8 is a
large current port, which can drive 20 mA (@VOL = 1.5 V) when a low level signal is output. Any
of these ports can become an input port immediately after a reset. They can also be used as I/O
pins of the on-chip peripheral modules or external interrupt input pins, and these functions can be
switched depending on the register settings. The registers for selecting these functions can be
divided into two types: those included in I/O ports and those included in each on-chip peripheral
module. General I/O ports are comprised of the port control register for controlling inputs/outputs
and the port data register for storing output data and can select inputs/outputs in bit units. For
functions in each port, see Appendix B.1, I/O Port Block Diagrams. For the execution of bit
manipulation instructions to the port control register and port data register, see section 2.8.3, Bit
Manipulation Instruction.

Section 10 Timer V
Section 10 Timer V
Timer V is an 8-bit timer based on an 8-bit counter. Timer V counts external events. Comparematch signals with two registers can also be used to reset the counter, request an interrupt, or
output a pulse signal with an arbitrary duty cycle. Counting can be initiated by a trigger input at
the TRGV pin, enabling pulse output control to be synchronized to the trigger, with an arbitrary
delay from the trigger input. Figure 10.1 shows a block diagram of timer V.
10.1
Features
• Choice of seven clock signals is available.
Choice of six internal clock sources (φ/128, φ/64, φ/32, φ/16, φ/8, φ/4) or an external clock.
• Counter can be cleared by compare match A or B, or by an external reset signal. If the count
stop function is selected, the counter can be halted when cleared.
• Timer output is controlled by two independent compare match signals, enabling pulse output
with an arbitrary duty cycle, PWM output, and other applications.
• Three interrupt sources: compare match A, compare match B, timer overflow
• Counting can be initiated by trigger input at the TRGV pin. The rising edge, falling edge, or
both edges of the TRGV input can be selected.

•
Timer counter V (TCNTV)
Timer constant register A (TCORA)
Timer constant register B (TCORB)
Timer control register V0 (TCRV0)
Timer control/status register V (TCSRV)
Timer control register V1 (TCRV1)
10.3.1
Timer Counter V (TCNTV)
TCNTV is an 8-bit up-counter. The clock source is selected by bits CKS2 to CKS0 in timer
control register V0 (TCRV0). The TCNTV value can be read and written by the CPU at any time.
TCNTV can be cleared by an external reset input signal, or by compare match A or B. The
clearing signal is selected by bits CCLR1 and CCLR0 in TCRV0.
When TCNTV overflows, OVF is set to 1 in timer control/status register V (TCSRV).
TCNTV is initialized to H'00.

Section 10 Timer V
10.3.2
Time Constant Registers A and B (TCORA, TCORB)
TCORA and TCORB have the same function.
TCORA and TCORB are 8-bit read/write registers.
TCORA and TCNTV are compared at all times. When the TCORA and TCNTV contents match,
CMFA is set to 1 in TCSRV. If CMIEA is also set to 1 in TCRV0, a CPU interrupt is requested.
Note that they must not be compared during the T3 state of a TCORA write cycle.
Timer output from the TMOV pin can be controlled by the identifying signal (compare match A)
and the settings of bits OS3 to OS0 in TCSRV.
TCORA and TCORB are initialized to H'FF.

Operation
10.4.1
Timer V Operation
1. According to table 10.2, six internal/external clock signals output by prescaler S can be
selected as the timer V operating clock signals. When the operating clock signal is selected,
TCNTV starts counting-up. Figure 10.2 shows the count timing with an internal clock signal
selected, and figure 10.3 shows the count timing with both edges of an external clock signal
selected.
2. When TCNTV overflows (changes from H'FF to H'00), the overflow flag (OVF) in TCRV0
will be set. The timing at this time is shown in figure 10.4. An interrupt request is sent to the
CPU when OVIE in TCRV0 is 1.
3. TCNTV is constantly compared with TCORA and TCORB. Compare match flag A or B
(CMFA or CMFB) is set to 1 when TCNTV matches TCORA or TCORB, respectively. The
compare-match signal is generated in the last state in which the values match. Figure 10.5
shows the timing. An interrupt request is generated for the CPU when CMIEA or CMIEB in
TCRV0 is 1.
4. When a compare match A or B is generated, the TMOV responds with the output value
selected by bits OS3 to OS0 in TCSRV. Figure 10.6 shows the timing when the output is
toggled by compare match A.
5. When CCLR1 or CCLR0 in TCRV0 is 01 or 10, TCNTV can be cleared by the corresponding
compare match. Figure 10.7 shows the timing.
6. When CCLR1 or CCLR0 in TCRV0 is 11, TCNTV can be cleared by the rising edge of the
input of TMRIV pin. A TMRIV input pulse-width of at least 1.5 system clocks is necessary.
Figure 10.8 shows the timing.
7. When a counter-clearing source is generated with TRGE in TCRV1 set to 1, the counting-up is
halted as soon as TCNTV is cleared. TCNTV resumes counting-up when the edge selected by
TVEG1 or TVEG0 in TCRV1 is input from the TGRV pin.

Figure 10.9 shows an example of output of pulses with an arbitrary duty cycle.
1. Set bits CCLR1 and CCLR0 in TCRV0 so that TCNTV will be cleared by compare match with
TCORA.
2. Set bits OS3 to OS0 in TCSRV so that the output will go to 1 at compare match with TCORA
and to 0 at compare match with TCORB.
3. Set bits CKS2 to CKS0 in TCRV0 and bit ICKS0 in TCRV1 to select the desired clock source.
4. With these settings, a waveform is output without further software intervention, with a period
determined by TCORA and a pulse width determined by TCORB.

Pulse Output with Arbitrary Pulse Width and Delay from TRGV Input
The trigger function can be used to output a pulse with an arbitrary pulse width at an arbitrary
delay from the TRGV input, as shown in figure 10.10. To set up this output:
1. Set bits CCLR1 and CCLR0 in TCRV0 so that TCNTV will be cleared by compare match with
TCORB.
2. Set bits OS3 to OS0 in TCSRV so that the output will go to 1 at compare match with TCORA
and to 0 at compare match with TCORB.
3. Set bits TVEG1 and TVEG0 in TCRV1 and set TRGE to select the falling edge of the TRGV
input.
4. Set bits CKS2 to CKS0 in TCRV0 and bit ICKS0 in TCRV1 to select the desired clock source.
5. After these settings, a pulse waveform will be output without further software intervention,
with a delay determined by TCORA from the TRGV input, and a pulse width determined by
(TCORB – TCORA).

Usage Notes
The following types of contention or operation can occur in timer V operation.
1.
2.
3.
4.
Writing to registers is performed in the T3 state of a TCNTV write cycle. If a TCNTV clear
signal is generated in the T3 state of a TCNTV write cycle, as shown in figure 10.11, clearing
takes precedence and the write to the counter is not carried out. If counting-up is generated in
the T3 state of a TCNTV write cycle, writing takes precedence.
If a compare match is generated in the T3 state of a TCORA or TCORB write cycle, the write
to TCORA or TCORB takes precedence and the compare match signal is inhibited. Figure
10.12 shows the timing.
If compare matches A and B occur simultaneously, any conflict between the output selections
for compare match A and compare match B is resolved by the following priority: toggle
output > output 1 > output 0.
Depending on the timing, TCNTV may be incremented by a switch between different internal
clock sources. When TCNTV is internally clocked, an increment pulse is generated from the
falling edge of an internal clock signal, that is divided system clock (φ). Therefore, as shown
in figure 10.3 the switch is from a high clock signal to a low clock signal, the switchover is
seen as a falling edge, causing TCNTV to increment. TCNTV can also be incremented by a
switch between internal and external clocks.

Section 11 Timer W
The timer W has a 16-bit timer having output compare and input capture functions. The timer W
can count external events and output pulses with an arbitrary duty cycle by compare match
between the timer counter and four general registers. Thus, it can be applied to various systems.
11.1
Features
• Selection of five counter clock sources: four internal clocks (φ, φ/2, φ/4, and φ/8) and an
external clock (external events can be counted)
• Capability to process up to four pulse outputs or four pulse inputs
• Four general registers:
 Independently assignable output compare or input capture functions
 Usable as two pairs of registers; one register of each pair operates as a buffer for the output
compare or input capture register
• Four selectable operating modes :
 Waveform output by compare match
Selection of 0 output, 1 output, or toggle output
 Input capture function
Rising edge, falling edge, or both edges
 Counter clearing function
Counters can be cleared by compare match
 PWM mode
Up to three-phase PWM output can be provided with desired duty ratio.
• Any initial timer output value can be set
• Five interrupt sources
Four compare match/input capture interrupts and an overflow interrupt.
Table 11.1 summarizes the timer W functions, and figure 11.1 shows a block diagram of the timer
W.

Section 11 Timer W
11.3.7
Timer Counter (TCNT)
TCNT is a 16-bit readable/writable up-counter. The clock source is selected by bits CKS2 to
CKS0 in TCRW. TCNT can be cleared to H'0000 through a compare match with GRA by setting
the CCLR in TCRW to 1. When TCNT overflows (changes from H'FFFF to H'0000), the OVF
flag in TSRW is set to 1. If OVIE in TIERW is set to 1 at this time, an interrupt request is
generated. TCNT must always be read or written in 16-bit units; 8-bit access is not allowed.
TCNT is initialized to H'0000 by a reset.
11.3.8
General Registers A to D (GRA to GRD)
Each general register is a 16-bit readable/writable register that can function as either an outputcompare register or an input-capture register. The function is selected by settings in TIOR0 and
TIOR1.
When a general register is used as an input-compare register, its value is constantly compared with
the TCNT value. When the two values match (a compare match), the corresponding flag (IMFA,
IMFB, IMFC, or IMFD) in TSRW is set to 1. An interrupt request is generated at this time, when
IMIEA, IMIEB, IMIEC, or IMIED is set to 1. Compare match output can be selected in TIOR.
When a general register is used as an input-capture register, an external input-capture signal is
detected and the current TCNT value is stored in the general register. The corresponding flag
(IMFA, IMFB, IMFC, or IMFD) in TSRW is set to 1. If the corresponding interrupt-enable bit
(IMIEA, IMIEB, IMIEC, or IMIED) in TSRW is set to 1 at this time, an interrupt request is
generated. The edge of the input-capture signal is selected in TIOR.
GRC and GRD can be used as buffer registers of GRA and GRB, respectively, by setting BUFEA
and BUFEB in TMRW.
For example, when GRA is set as an output-compare register and GRC is set as the buffer register
for GRA, the value in the buffer register GRC is sent to GRA whenever compare match A is
generated.
When GRA is set as an input-capture register and GRC is set as the buffer register for GRA, the
value in TCNT is transferred to GRA and the value in the buffer register GRC is transferred to
GRA whenever an input capture is generated.
GRA to GRD must be written or read in 16-bit units; 8-bit access is not allowed. GRA to GRD are
initialized to H'FFFF by a reset.

Operation
The timer W has the following operating modes.
• Normal Operation
• PWM Operation
11.4.1
Normal Operation
TCNT performs free-running or periodic counting operations. After a reset, TCNT is set as a freerunning counter. When the CTS bit in TMRW is set to 1, TCNT starts incrementing the count.
When the count overflows from H'FFFF to H'0000, the OVF flag in TSRW is set to 1. If the OVIE
in TIERW is set to 1, an interrupt request is generated. Figure 11.2 shows free-running counting.

Periodic counting operation can be performed when GRA is set as an output compare register and
bit CCLR in TCRW is set to 1. When the count matches GRA, TCNT is cleared to H'0000, the
IMFA flag in TSRW is set to 1. If the corresponding IMIEA bit in TIERW is set to 1, an interrupt
request is generated. TCNT continues counting from H'0000. Figure 11.3 shows periodic
counting.

11.4 shows an example of 0 and 1 output when TCNT operates as a free-running counter, 1 output
is selected for compare match A, and 0 output is selected for compare match B. When signal is

The TCNT value can be captured into a general register (GRA, GRB, GRC, or GRD) when a
signal level changes at an input-capture pin (FTIOA, FTIOB, FTIOC, or FTIOD). Capture can
take place on the rising edge, falling edge, or both edges. By using the input-capture function, the
pulse width and periods can be measured. Figure 11.7 shows an example of input capture when
both edges of FTIOA and the falling edge of FTIOB are selected as capture edges. TCNT operates
as a free-running counter.

11.4.2
PWM Operation
In PWM mode, PWM waveforms are generated by using GRA as the period register and GRB,
GRC, and GRD as duty registers. PWM waveforms are output from the FTIOB, FTIOC, and
FTIOD pins. Up to three-phase PWM waveforms can be output. In PWM mode, a general register
functions as an output compare register automatically. The output level of each pin depends on the
corresponding timer output level set bit (TOB, TOC, and TOD) in TCRW. When TOB is 1, the
FTIOB output goes to 1 at compare match A and to 0 at compare match B. When TOB is 0, the
FTIOB output goes to 0 at compare match A and to 1 at compare match B. Thus the compare
match output level settings in TIOR0 and TIOR1 are ignored for the output pin set to PWM mode.
If the same value is set in the cycle register and the duty register, the output does not change when
a compare match occurs.
Figure 11.9 shows an example of operation in PWM mode. The output signals go to 1 and TCNT
is cleared at compare match A, and the output signals go to 0 at compare match B, C, and D (TOB,
TOC, and TOD = 1: initial output values are set to 1).

Figure 11.11 shows an example of buffer operation when the FTIOB pin is set to PWM mode and
GRD is set as the buffer register for GRB. TCNT is cleared by compare match A, and FTIOB
outputs 1 at compare match B and 0 at compare match A.
Due to the buffer operation, the FTIOB output level changes and the value of buffer register GRD
is transferred to GRB whenever compare match B occurs. This procedure is repeated every time
compare match B occurs.

The compare match signal is generated in the last state in which TCNT and GR match (when
TCNT changes from the matching value to the next value). When the compare match signal is
generated, the output value selected in TIOR is output at the compare match output pin (FTIOA,
FTIOB, FTIOC, or FTIOD).
When TCNT matches GR, the compare match signal is generated only after the next counter clock
pulse is input.

Timing of IMFA to IMFD Flag Setting at Compare Match
If a general register (GRA, GRB, GRC, or GRD) is used as an output compare register, the
corresponding IMFA, IMFB, IMFC, or IMFD flag is set to 1 when TCNT matches the general
register.
The compare match signal is generated in the last state in which the values match (when TCNT is
updated from the matching count to the next count). Therefore, when TCNT matches a general
register, the compare match signal is generated only after the next TCNT clock pulse is input.

Usage Notes
The following types of contention or operation can occur in timer W operation.
1. The pulse width of the input clock signal and the input capture signal must be at least two
system clock (φ) cycles; shorter pulses will not be detected correctly.
2. Writing to registers is performed in the T2 state of a TCNT write cycle.
If counter clear signal occurs in the T2 state of a TCNT write cycle, clearing of the counter
takes priority and the write is not performed, as shown in figure 11.24. If counting-up is
generated in the TCNT write cycle to contend with the TCNT counting-up, writing takes
precedence.
3. Depending on the timing, TCNT may be incremented by a switch between different internal
clock sources. When TCNT is internally clocked, an increment pulse is generated from the
rising edge of an internal clock signal, that is divided system clock (φ). Therefore, as shown in
figure 11.25 the switch is from a low clock signal to a high clock signal, the switchover is seen
as a rising edge, causing TCNT to increment.
4. If timer W enters module standby mode while an interrupt request is generated, the interrupt
request cannot be cleared. Before entering module standby mode, disable interrupt requests.

5. The TOA to TOD bits in TCRW decide the value of the FTIO pin, which is output until the
first compare match occurs. Once a compare match occurs and this compare match changes the
values of FTIOA to FTIOD output, the values of the FTIOA to FTIOD pin output and the
values read from the TOA to TOD bits may differ. Moreover, when the writing to TCRW and
the generation of the compare match A to D occur at the same timing, the writing to TCRW
has the priority. Thus, output change due to the compare match is not reflected to the FTIOA
to FTIOD pins. Therefore, when bit manipulation instruction is used to write to TCRW, the
values of the FTIOA to FTIOD pin output may result in an unexpected result. When TCRW is
to be written to while compare match is operating, stop the counter once before accessing to
TCRW, read the port 8 state to reflect the values of FTIOA to FTIOD output, to TOA to TOD,
and then restart the counter. Figure 11.26 shows an example when the compare match and the
bit manipulation instruction to TCRW occur at the same timing.
TCRW has been set to H'06. Compare match B and compare match C are used. The FTIOB pin is in the 1 output state,
and is set to the toggle output or the 0 output by compare match B.
When BCLR#2, @TCRW is executed to clear the TOC bit (the FTIOC signal is low) and compare match B occurs
at the same timing as shown below, the H'02 writing to TCRW has priority and compare match B does not drive the FTIOB signal low;
the FTIOB signal remains high.

Section 12 Watchdog Timer
The watchdog timer is an 8-bit timer that can generate an internal reset signal for this LSI if a
system crash prevents the CPU from writing to the timer counter, thus allowing it to overflow.
The block diagram of the watchdog timer is shown in figure 12.1.

12.3
Operation
The watchdog timer is provided with an 8-bit counter. If 1 is written to WDON while writing 0 to
B2WI when the TCSRWE bit in TCSRWD is set to 1, TCWD begins counting up. (To operate
the watchdog timer, two write accesses to TCSRWD are required.) When a clock pulse is input
after the TCWD count value has reached H'FF, the watchdog timer overflows and an internal reset
signal is generated. The internal reset signal is output for a period of 256 φosc clock cycles. TCWD
is a writable counter, and when a value is set in TCWD, the count-up starts from that value. An
overflow period in the range of 1 to 256 input clock cycles can therefore be set, according to the
TCWD set value.
Figure 12.2 shows an example of watchdog timer operation.
Example:
With 30ms overflow period when φ = 4 MHz
4 × 106
8192
× 30 × 10–3 = 14.6
Therefore, 256 – 15 = 241 (H'F1) is set in TCW.

Section 13 Serial Communication Interface 3 (SCI3)
This LSI includes a serial communication interface 3 (SCI3). The SCI3 can handle both
asynchronous and clocked synchronous serial communication. In asynchronous mode, serial data
communication can be carried out using standard asynchronous communication chips such as a
Universal Asynchronous Receiver/Transmitter (UART) or an Asynchronous Communication
Interface Adapter (ACIA). A function is also provided for serial communication between
processors (multiprocessor communication function).
Table 13.1 shows the SCI3 channel configuration and figure 13.1 shows a block diagram of the
SCI3. Since pin functions are identical for each of the two channels (SCI3 and SCI3_2), separate
explanations are not given in this section.
13.1
Features
• Choice of asynchronous or clocked synchronous serial communication mode
• Full-duplex communication capability
The transmitter and receiver are mutually independent, enabling transmission and reception to
be executed simultaneously.
Double-buffering is used in both the transmitter and the receiver, enabling continuous
transmission and continuous reception of serial data.
• On-chip baud rate generator allows any bit rate to be selected
• External clock or on-chip baud rate generator can be selected as a transfer clock source.
• Six interrupt sources
Transmit-end, transmit-data-empty, receive-data-full, overrun error, framing error, and parity
error.

Section 13 Serial Communication Interface 3 (SCI3)
13.3.1
Receive Shift Register (RSR)
RSR is a shift register that is used to receive serial data input from the RXD pin and convert it into
parallel data. When one frame of data has been received, it is transferred to RDR automatically.
RSR cannot be directly accessed by the CPU.
13.3.2
Receive Data Register (RDR)
RDR is an 8-bit register that stores received data. When the SCI3 has received one frame of serial
data, it transfers the received serial data from RSR to RDR, where it is stored. After this, RSR is
receive-enabled. As RSR and RDR function as a double buffer in this way, continuous receive
operations are possible. After confirming that the RDRF bit in SSR is set to 1, read RDR only
once. RDR cannot be written to by the CPU. RDR is initialized to H'00.
13.3.3
Transmit Shift Register (TSR)
TSR is a shift register that transmits serial data. To perform serial data transmission, the SCI3 first
transfers transmit data from TDR to TSR automatically, then sends the data that starts from the
LSB to the TXD pin. TSR cannot be directly accessed by the CPU.
13.3.4
Transmit Data Register (TDR)
TDR is an 8-bit register that stores data for transmission. When the SCI3 detects that TSR is
empty, it transfers the transmit data written in TDR to TSR and starts transmission. The doublebuffered structure of TDR and TSR enables continuous serial transmission. If the next transmit
data has already been written to TDR during transmission of one-frame data, the SCI3 transfers
the written data to TSR to continue transmission. To achieve reliable serial transmission, write
transmit data to TDR only once after confirming that the TDRE bit in SSR is set to 1. TDR is
initialized to H'FF.

Bit Rate Register (BRR)
BRR is an 8-bit register that adjusts the bit rate. The initial value of BRR is H'FF. Table 13.3
shows the relationship between the N setting in BRR and the n setting in bits CKS1 and CKS0 of
SMR in asynchronous mode. Table 13.4 shows the maximum bit rate for each frequency in
asynchronous mode. The values shown in both tables 13.3 and 13.4 are values in active (highspeed) mode. Table 13.5 shows the relationship between the N setting in BRR and the n setting in
bits CKS1 and CKS0 of SMR in clocked synchronous mode. The values shown in table 13.5 are
values in active (high-speed) mode. The N setting in BRR and error for other operating
frequencies and bit rates can be obtained by the following formulas:
[Asynchronous Mode]
N=

Operation in Asynchronous Mode
Figure 13.2 shows the general format for asynchronous serial communication. One character (or
frame) consists of a start bit (low level), followed by data (in LSB-first order), a parity bit (high or
low level), and finally stop bits (high level). Inside the SCI3, the transmitter and receiver are
independent units, enabling full-duplex. Both the transmitter and the receiver also have a doublebuffered structure, so data can be read or written during transmission or reception, enabling
continuous data transfer.

Clock
Either an internal clock generated by the on-chip baud rate generator or an external clock input at
the SCK3 pin can be selected as the SCI3’s serial clock, according to the setting of the COM bit in
SMR and the CKE0 and CKE1 bits in SCR3. When an external clock is input at the SCK3 pin, the
clock frequency should be 16 times the bit rate used.
When the SCI3 is operated on an internal clock, the clock can be output from the SCK3 pin. The
frequency of the clock output in this case is equal to the bit rate, and the phase is such that the
rising edge of the clock is in the middle of the transmit data, as shown in figure 13.3.

SCI3 Initialization
Before transmitting and receiving data, you should first clear the TE and RE bits in SCR3 to 0,
then initialize the SCI3 as described below. When the operating mode, or transfer format, is
changed for example, the TE and RE bits must be cleared to 0 before making the change using the
following procedure. When the TE bit is cleared to 0, the TDRE flag is set to 1. Note that clearing
the RE bit to 0 does not initialize the contents of the RDRF, PER, FER, and OER flags, or the
contents of RDR. When the external clock is used in asynchronous mode, the clock must be
supplied even during initialization.
[1]
Start initialization
When the clock output is selected in
asynchronous mode, clock is output
immediately after CKE1 and CKE0
settings are made. When the clock
output is selected at reception in clocked
synchronous mode, clock is output
immediately after CKE1, CKE0, and RE
are set to 1.

[4]
Wait at least one bit interval, then set the
TE bit or RE bit in SCR3 to 1. RE
settings enable the RXD pin to be used.
For transmission, set the TXD bit in
PMR1 to 1 to enable the TXD output pin
to be used. Also set the RIE, TIE, TEIE,
and MPIE bits, depending on whether
interrupts are required. In asynchronous
mode, the bits are marked at
transmission and idled at reception to
wait for the start bit.
No
1-bit interval elapsed?
Yes
Set TE and RE bits in

and MPIE bits. For transmit (TE=1),
also set the TxD bit in PMR1.
<Initialization completion>
[4]
Set the clock selection in SCR3.
Be sure to clear bits RIE, TIE, TEIE, and
MPIE, and bits TE and RE, to 0.

Data Transmission
Figure 13.5 shows an example of operation for transmission in asynchronous mode. In
transmission, the SCI3 operates as described below.
1. The SCI3 monitors the TDRE flag in SSR. If the flag is cleared to 0, the SCI3 recognizes that
data has been written to TDR, and transfers the data from TDR to TSR.
2. After transferring data from TDR to TSR, the SCI3 sets the TDRE flag to 1 and starts
transmission. If the TIE bit is set to 1 at this time, a TXI interrupt request is generated.
Continuous transmission is possible because the TXI interrupt routine writes next transmit data
to TDR before transmission of the current transmit data has been completed.
3. The SCI3 checks the TDRE flag at the timing for sending the stop bit.
4. If the TDRE flag is 0, the data is transferred from TDR to TSR, the stop bit is sent, and then
serial transmission of the next frame is started.
5. If the TDRE flag is 1, the TEND flag in SSR is set to 1, the stop bit is sent, and then the “mark
state” is entered, in which 1 is output. If the TEIE bit in SCR3 is set to 1 at this time, a TEI
interrupt request is generated.

Serial Data Reception
Figure 13.7 shows an example of operation for reception in asynchronous mode. In serial
reception, the SCI3 operates as described below.
1. The SCI3 monitors the communication line. If a start bit is detected, the SCI3 performs
internal synchronization, receives receive data in RSR, and checks the parity bit and stop bit.
2. If an overrun error occurs (when reception of the next data is completed while the RDRF flag
is still set to 1), the OER bit in SSR is set to 1. If the RIE bit in SCR3 is set to 1 at this time, an
ERI interrupt request is generated. Receive data is not transferred to RDR.
3. If a parity error is detected, the PER bit in SSR is set to 1 and receive data is transferred to
RDR. If the RIE bit in SCR3 is set to 1 at this time, an ERI interrupt request is generated.
4. If a framing error is detected (when the stop bit is 0), the FER bit in SSR is set to 1 and receive
data is transferred to RDR. If the RIE bit in SCR3 is set to 1 at this time, an ERI interrupt
request is generated.
5. If reception is completed successfully, the RDRF bit in SSR is set to 1, and receive data is
transferred to RDR. If the RIE bit in SCR3 is set to 1 at this time, an RXI interrupt request is
generated. Continuous reception is possible because the RXI interrupt routine reads the receive
data transferred to RDR before reception of the next receive data has been completed.

Operation in Clocked Synchronous Mode
Figure 13.9 shows the general format for clocked synchronous communication. In clocked
synchronous mode, data is transmitted or received synchronous with clock pulses. A single
character in the transmit data consists of the 8-bit data starting from the LSB. In clocked
synchronous serial communication, data on the transmission line is output from one falling edge of
the synchronization clock to the next. In clocked synchronous mode, the SCI3 receives data in
synchronous with the rising edge of the synchronization clock. After 8-bit data is output, the
transmission line holds the MSB state. In clocked synchronous mode, no parity or multiprocessor
bit is added. Inside the SCI3, the transmitter and receiver are independent units, enabling fullduplex communication through the use of a common clock. Both the transmitter and the receiver
also have a double-buffered structure, so data can be read or written during transmission or
reception, enabling continuous data transfer.

Clock
Either an internal clock generated by the on-chip baud rate generator or an external
synchronization clock input at the SCK3 pin can be selected, according to the setting of the COM
bit in SMR and CKE0 and CKE1 bits in SCR3. When the SCI3 is operated on an internal clock,
the synchronization clock is output from the SCK3 pin. Eight synchronization clock pulses are
output in the transfer of one character, and when no transfer is performed the clock is fixed high.

Serial Data Transmission
Figure 13.10 shows an example of SCI3 operation for transmission in clocked synchronous mode.
In serial transmission, the SCI3 operates as described below.
1. The SCI3 monitors the TDRE flag in SSR, and if the flag is 0, the SCI3 recognizes that data
has been written to TDR, and transfers the data from TDR to TSR.
2. The SCI3 sets the TDRE flag to 1 and starts transmission. If the TIE bit in SCR3 is set to 1 at
this time, a transmit data empty interrupt (TXI) is generated.
3. 8-bit data is sent from the TXD pin synchronized with the output clock when output clock
mode has been specified, and synchronized with the input clock when use of an external clock
has been specified. Serial data is transmitted sequentially from the LSB (bit 0), from the TXD
pin.
4. The SCI3 checks the TDRE flag at the timing for sending the MSB (bit 7).
5. If the TDRE flag is cleared to 0, data is transferred from TDR to TSR, and serial transmission
of the next frame is started.
6. If the TDRE flag is set to 1, the TEND flag in SSR is set to 1, and the TDRE flag maintains
the output state of the last bit. If the TEIE bit in SCR3 is set to 1 at this time, a TEI interrupt
request is generated.
7. The SCK3 pin is fixed high at the end of transmission.
Figure 13.11 shows a sample flow chart for serial data transmission. Even if the TDRE flag is
cleared to 0, transmission will not start while a receive error flag (OER, FER, or PER) is set to 1.
Make sure that the receive error flags are cleared to 0 before starting transmission.

The following procedure should be used for simultaneous serial data transmit and receive
operations. To switch from transmit mode to simultaneous transmit and receive mode, after
checking that the SCI3 has finished transmission and the TDRE and TEND flags are set to 1, clear
TE to 0. Then simultaneously set TE and RE to 1 with a single instruction. To switch from receive
mode to simultaneous transmit and receive mode, after checking that the SCI3 has finished
reception, clear RE to 0. Then after checking that the RDRF and receive error flags (OER, FER,
and PER) are cleared to 0, simultaneously set TE and RE to 1 with a single instruction.

Multiprocessor Communication Function
Use of the multiprocessor communication function enables data transfer between a number of
processors sharing communication lines by asynchronous serial communication using the
multiprocessor format, in which a multiprocessor bit is added to the transfer data. When
multiprocessor communication is performed, each receiving station is addressed by a unique ID
code. The serial communication cycle consists of two component cycles; an ID transmission cycle
that specifies the receiving station, and a data transmission cycle. The multiprocessor bit is used to
differentiate between the ID transmission cycle and the data transmission cycle. If the
multiprocessor bit is 1, the cycle is an ID transmission cycle; if the multiprocessor bit is 0, the
cycle is a data transmission cycle. Figure 13.15 shows an example of inter-processor
communication using the multiprocessor format. The transmitting station first sends the ID code
of the receiving station with which it wants to perform serial communication as data with a 1
multiprocessor bit added. It then sends transmit data as data with a 0 multiprocessor bit added.
When data with a 1 multiprocessor bit is received, the receiving station compares that data with its
own ID. The station whose ID matches then receives the data sent next. Stations whose IDs do not
match continue to skip data until data with a 1 multiprocessor bit is again received.
The SCI3 uses the MPIE bit in SCR3 to implement this function. When the MPIE bit is set to 1,
transfer of receive data from RSR to RDR, error flag detection, and setting the SSR status flags,
RDRF, FER, and OER, to 1, are inhibited until data with a 1 multiprocessor bit is received. On
reception of a receive character with a 1 multiprocessor bit, the MPBR bit in SSR is set to 1 and
the MPIE bit is automatically cleared, thus normal reception is resumed. If the RIE bit in SCR3 is
set to 1 at this time, an RXI interrupt is generated.
When the multiprocessor format is selected, the parity bit setting is rendered invalid. All other bit
settings are the same as those in normal asynchronous mode. The clock used for multiprocessor
communication is the same as that in normal asynchronous mode.

Multiprocessor Serial Data Reception
Figure 13.17 shows a sample flowchart for multiprocessor serial data reception. If the MPIE bit in
SCR3 is set to 1, data is skipped until data with a 1 multiprocessor bit is sent. On receiving data
with a 1 multiprocessor bit, the receive data is transferred to RDR. An RXI interrupt request is
generated at this time. All other SCI3 operations are the same as those in asynchronous mode.
Figure 13.18 shows an example of SCI3 operation for multiprocessor format reception.

13.7
Interrupts
SCI3 creates the following six interrupt requests: transmission end, transmit data empty, receive
data full, and receive errors (overrun error, framing error, and parity error). Table 13.7 shows the
interrupt sources.

Setting OER, FER, and PER in SSR
The initial value of the TDRE flag in SSR is 1. Thus, when the TIE bit in SCR3 is set to 1 before
transferring the transmit data to TDR, a TXI interrupt request is generated even if the transmit data
is not ready. The initial value of the TEND flag in SSR is 1. Thus, when the TEIE bit in SCR3 is
set to 1 before transferring the transmit data to TDR, a TEI interrupt request is generated even if
the transmit data has not been sent. It is possible to make use of the most of these interrupt
requests efficiently by transferring the transmit data to TDR in the interrupt routine. To prevent the
generation of these interrupt requests (TXI and TEI), set the enable bits (TIE and TEIE) that
correspond to these interrupt requests to 1, after transferring the transmit data to TDR.

Usage Notes
13.8.1
Break Detection and Processing
When framing error detection is performed, a break can be detected by reading the RXD pin value
directly. In a break, the input from the RXD pin becomes all 0s, setting the FER flag, and possibly
the PER flag. Note that as the SCI3 continues the receive operation after receiving a break, even if
the FER flag is cleared to 0, it will be set to 1 again.
13.8.2
Mark State and Break Sending
When TE is 0, the TXD pin is used as an I/O port whose direction (input or output) and level are
determined by PCR and PDR. This can be used to set the TXD pin to mark state (high level) or
send a break during serial data transmission. To maintain the communication line at mark state
until TE is set to 1, set both PCR and PDR to 1. As TE is cleared to 0 at this point, the TXD pin
becomes an I/O port, and 1 is output from the TXD pin. To send a break during serial
transmission, first set PCR to 1 and clear PDR to 0, and then clear TE to 0. When TE is cleared to
0, the transmitter is initialized regardless of the current transmission state, the TXD pin becomes
an I/O port, and 0 is output from the TXD pin.
13.8.3
Receive Error Flags and Transmit Operations (Clocked Synchronous Mode Only)
Transmission cannot be started when a receive error flag (OER, PER, or FER) is set to 1, even if
the TDRE flag is cleared to 0. Be sure to clear the receive error flags to 0 before starting
transmission. Note also that receive error flags cannot be cleared to 0 even if the RE bit is cleared
to 0.

13.8.4
Receive Data Sampling Timing and Reception Margin in Asynchronous Mode
In asynchronous mode, the SCI3 operates on a basic clock with a frequency of 16 times the
transfer rate. In reception, the SCI3 samples the falling edge of the start bit using the basic clock,
and performs internal synchronization. Receive data is latched internally at the rising edge of the
8th pulse of the basic clock as shown in figure 13.19. Thus, the reception margin in asynchronous
mode is given by formula (1) below.

N: Ratio of bit rate to clock (N = 16)
D: Clock duty (D = 0.5 to 1.0)
L: Frame length (L = 9 to 12)
F: Absolute value of clock rate deviation
Assuming values of F (absolute value of clock rate deviation) = 0 and D (clock duty) = 0.5 in
formula (1), the reception margin can be given by the formula.
M = {0.5 – 1/(2 × 16)} × 100 [%] = 46.875%
However, this is only the computed value, and a margin of 20% to 30% should be allowed for in
system design.

14.3.1
A/D Data Registers A to D (ADDRA to ADDRD)
There are four 16-bit read-only ADDR registers; ADDRA to ADDRD, used to store the results of
A/D conversion. The ADDR registers, which store a conversion result for each channel, are
shown in table 14.2.
The converted 10-bit data is stored in bits 6 to 15. The lower 6 bits are always read as 0.
The data bus between the CPU and the A/D converter is 8 bits wide. The upper byte can be read
directly from the CPU, however the lower byte should be read via a temporary register. The
temporary register contents are transferred from the ADDR when the upper byte data is read.
Therefore byte access to ADDR should be done by reading the upper byte first then the lower one.
Word access is also possible. ADDR is initialized to H'0000.

14.4
Operation
The A/D converter operates by successive approximation with 10-bit resolution. It has two
operating modes; single mode and scan mode. When changing the operating mode or analog input
channel, in order to prevent incorrect operation, first clear the bit ADST to 0 in ADCSR. The
ADST bit can be set at the same time as the operating mode or analog input channel is changed.
14.4.1
Single Mode
In single mode, A/D conversion is performed once for the analog input on the specified single
channel as follows:
1.
2.
3.
4.
A/D conversion is started from the first channel when the ADST bit in ADCSR is set to 1,
according to software or external trigger input.
When A/D conversion is completed, the result is transferred to the corresponding A/D data
register to the channel.
On completion of conversion, the ADF bit in ADCSR is set to 1. If the ADIE bit is set to 1 at
this time, an ADI interrupt request is generated.
The ADST bit remains set to 1 during A/D conversion. When A/D conversion ends, the
ADST bit is automatically cleared to 0 and the A/D converter enters the wait state.
14.4.2
Scan Mode
In scan mode, A/D conversion is performed sequentially for the analog input on the specified
channels (four channels maximum) as follows:
1. When the ADST bit is set to 1 by software, or external trigger input, A/D conversion starts on
the first channel in the group.
2. When A/D conversion for each channel is completed, the result is sequentially transferred to
the A/D data register corresponding to each channel.
3. When conversion of all the selected channels is completed, the ADF flag in ADCSR is set to 1.
If the ADIE bit is set to 1 at this time, an ADI interrupt is requested. Conversion of the first
channel in the group starts again.
4. The ADST bit is not automatically cleared to 0. Steps [2] to [3] are repeated as long as the
ADST bit remains set to 1. When the ADST bit is cleared to 0, A/D conversion stops.

Section 14 A/D Converter
14.4.3
Input Sampling and A/D Conversion Time
The A/D converter has a built-in sample-and-hold circuit. The A/D converter samples the analog
input when the A/D conversion start delay time (tD) has passed after the ADST bit is set to 1, then
starts conversion. Figure 14.2 shows the A/D conversion timing. Table 14.3 shows the A/D
conversion time.
As indicated in figure 14.2, the A/D conversion time includes tD and the input sampling time. The
length of tD varies depending on the timing of the write access to ADCSR. The total conversion
time therefore varies within the ranges indicated in table 14.3.
In scan mode, the values given in table 14.3 apply to the first conversion time. In the second and
subsequent conversions, the conversion time is 128 states (fixed) when CKS = 0 and 66 states
(fixed) when CKS = 1.

External Trigger Input Timing
A/D conversion can also be started by an external trigger input. When the TRGE bit is set to 1 in
ADCR, external trigger input is enabled at the ADTRG pin. A falling edge at the ADTRG input
pin sets the ADST bit to 1 in ADCSR, starting A/D conversion. Other operations, in both single
and scan modes, are the same as when the bit ADST has been set to 1 by software. Figure 14.3
shows the timing.

A/D Conversion Accuracy Definitions
This LSI's A/D conversion accuracy definitions are given below.
• Resolution
The number of A/D converter digital output codes
• Quantization error
The deviation inherent in the A/D converter, given by 1/2 LSB (see figure 14.4).
• Offset error
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from the minimum voltage value 0000000000 to 0000000001
(see figure 14.5).
• Full-scale error
The deviation of the analog input voltage value from the ideal A/D conversion characteristic
when the digital output changes from 1111111110 to 1111111111 (see figure 14.5).
• Nonlinearity error
The error with respect to the ideal A/D conversion characteristics between zero voltage and
full-scale voltage. Does not include offset error, full-scale error, or quantization error.
• Absolute accuracy
The deviation between the digital value and the analog input value. Includes offset error, fullscale error, quantization error, and nonlinearity error.

Usage Notes
14.6.1
Permissible Signal Source Impedance
This LSI's analog input is designed such that conversion accuracy is guaranteed for an input signal
for which the signal source impedance is 5 kΩ or less. This specification is provided to enable the
A/D converter's sample-and-hold circuit input capacitance to be charged within the sampling time;
if the sensor output impedance exceeds 5 kΩ, charging may be insufficient and it may not be
possible to guarantee A/D conversion accuracy. However, for A/D conversion in single mode with
a large capacitance provided externally, the input load will essentially comprise only the internal
input resistance of 10 kΩ, and the signal source impedance is ignored. However, as a low-pass
filter effect is obtained in this case, it may not be possible to follow an analog signal with a large
differential coefficient (e.g., 5 mV/µs or greater) (see figure 14.6). When converting a high-speed
analog signal or converting in scan mode, a low-impedance buffer should be inserted.
14.6.2
Influences on Absolute Accuracy
Adding capacitance results in coupling with GND, and therefore noise in GND may adversely
affect absolute accuracy. Be sure to make the connection to an electrically stable GND.
Care is also required to ensure that filter circuits do not interfere with digital signals or act as
antennas on the mounting board.

This LSI can include a power-on reset circuit and low-voltage detection circuit as optional circuits.
The low-voltage detection circuit consists of two circuits: LVDI (interrupt by low voltage detect)
and LVDR (reset by low voltage detect) circuits.
This circuit is used to prevent abnormal operation (runaway execution) from occurring due to the
power supply voltage fall and to recreate the state before the power supply voltage fall when the
power supply voltage rises again.
Even if the power supply voltage falls, the unstable state when the power supply voltage falls
below the guaranteed operating voltage can be removed by entering standby mode when
exceeding the guaranteed operating voltage and during normal operation. Thus, system stability
can be improved. If the power supply voltage falls more, the reset state is automatically entered. If
the power supply voltage rises again, the reset state is held for a specified period, then active mode
is automatically entered.
Figure 15.1 is a block diagram of the power-on reset circuit and the low-voltage detection circuit.
15.1
Features
• Power-on reset circuit
Uses an external capacitor to generate an internal reset signal when power is first supplied.
• Low-voltage detection circuit
LVDR: Monitors the power-supply voltage, and generates an internal reset signal when the
voltage falls below a specified value.
LVDI: Monitors the power-supply voltage, and generates an interrupt when the voltage falls
below or rises above respective specified values.
Two pairs of detection levels for reset generation voltage are available: when only the LVDR
circuit is used, or when the LVDI and LVDR circuits are both used.

Operation
15.3.1
Power-On Reset Circuit
Figure 15.2 shows the timing of the operation of the power-on reset circuit. As the power-supply
voltage rises, the capacitor which is externally connected to the RES pin is gradually charged via
the on-chip pull-up resistor (typ. 150 kΩ). Since the state of the RES pin is transmitted within the
chip, the prescaler S and the entire chip are in their reset states. When the level on the RES pin
reaches the specified value, the prescaler S is released from its reset state and it starts counting.
The OVF signal is generated to release the internal reset signal after the prescaler S has counted
131,072 clock (φ) cycles. The noise cancellation circuit of approximately 100 ns is incorporated to
prevent the incorrect operation of the chip by noise on the RES pin.
To achieve stable operation of this LSI, the power supply needs to rise to its full level and settles
within the specified time. The maximum time required for the power supply to rise and settle after
power has been supplied (tPWON) is determined by the oscillation frequency (fOSC) and capacitance
which is connected to RES pin (CRES). If tPWON means the time required to reach 90 % of power
supply voltage, the power supply circuit should be designed to satisfy the following formula.
tPWON (ms) ≤ 90 × CRES (µF) + 162/fOSC (MHz)
(tPWON ≤ 3000 ms, CRES ≥ 0.22 µF, and fOSC = 10 in 2-MHz to 10-MHz operation)
Note that the power supply voltage (Vcc) must fall below Vpor = 100 mV and rise after charge on
the RES pin is removed. To remove charge on the RES pin, it is recommended that the diode
should be placed near Vcc. If the power supply voltage (Vcc) rises from the point above Vpor, a
power-on reset may not occur.

Low-Voltage Detection Circuit
LVDR (Reset by Low Voltage Detect) Circuit
Figure 15.3 shows the timing of the LVDR function. The LVDR enters the module-standby state
after a power-on reset is canceled. To operate the LVDR, set the LVDE bit in LVDCR to 1, wait
for 50 µs (tLVDON) until the reference voltage and the low-voltage-detection power supply have
stabilized by a software timer, etc., then set the LVDRE bit in LVDCR to 1. After that, the output
settings of ports must be made. To cancel the low-voltage detection circuit, first the LVDRE bit
should be cleared to 0 and then the LVDE bit should be cleared to 0. The LVDE and LVDRE bits
must not be cleared to 0 simultaneously because incorrect operation may occur.
When the power-supply voltage falls below the Vreset voltage (typ. = 2.3 V or 3.6 V), the LVDR
clears the LVDRES signal to 0, and resets the prescaler S. The low-voltage detection reset state
remains in place until a power-on reset is generated. When the power-supply voltage rises above
the Vreset voltage again, the prescaler S starts counting. It counts 131,072 clock (φ) cycles, and
then releases the internal reset signal. In this case, the LVDE, LVDSEL, and LVDRE bits in
LVDCR are not initialized.
Note that if the power supply voltage (Vcc) falls below VLVDRmin = 1.0 V and then rises from that
point, the low-voltage detection reset may not occur.
If the power supply voltage (Vcc) falls below Vpor = 100 mV, a power-on reset occurs.

LVDI (Interrupt by Low Voltage Detect) Circuit
Figure 15.4 shows the timing of LVDI functions. The LVDI enters the module-standby state after
a power-on reset is canceled. To operate the LVDI, set the LVDE bit in LVDCR to 1, wait for 50
µs (tLVDON) until the reference voltage and the low-voltage-detection power supply have stabilized
by a software timer, etc., then set the LVDDE and LVDUE bits in LVDCR to 1. After that, the
output settings of ports must be made. To cancel the low-voltage detection circuit, first the
LVDDE and LVDUE bits should all be cleared to 0 and then the LVDE bit should be cleared to 0.
The LVDE bit must not be cleared to 0 at the same timing as the LVDDE and LVDUE bits
because incorrect operation may occur.
When the power-supply voltage falls below Vint (D) (typ. = 3.7 V) voltage, the LVDI clears the
LVDINT signal to 0 and the LVDDF bit in LVDSR is set to 1. If the LVDDE bit is 1 at this time,
an IRQ0 interrupt request is simultaneously generated. In this case, the necessary data must be
saved in the external EEPROM, etc, and a transition must be made to standby mode or subsleep
mode. Until this processing is completed, the power supply voltage must be higher than the lower
limit of the guaranteed operating voltage.
When the power-supply voltage does not fall below Vreset1 (typ. = 2.3 V) voltage but rises above
Vint (U) (typ. = 4.0 V) voltage, the LVDI sets the LVDINT signal to 1. If the LVDUE bit is 1 at
this time, the LVDUF bit in LVDSR is set to 1 and an IRQ0 interrupt request is simultaneously
generated.
If the power supply voltage (Vcc) falls below Vreset1 (typ. = 2.3 V) voltage, the LVDR function
is performed.

Procedures for Clearing Settings when Using LVDR and LVDI
To operate or release the low-voltage detection circuit normally, follow the procedure described
below. Figure 15.5 shows the timing for the operation and release of the low-voltage detection
circuit.
1. To operate the low-voltage detection circuit, set the LVDE bit in LVDCR to 1.
2. Wait for 50 µs (tLVDON) until the reference voltage and the low-voltage-detection power supply
have stabilized by a software timer, etc. Then, clear the LVDDF and LVDUF bits in LVDSR
to 0 and set the LVDRE, LVDDE, and LVDUE bits in LVDCR to 1, as required.
3. To release the low-voltage detection circuit, start by clearing all of the LVDRE, LVDDE, and
LVDUE bits to 0. Then clear the LVDE bit to 0. The LVDE bit must not be cleared to 0 at the
same timing as the LVDRE, LVDDE, and LVDUE bits because incorrect operation may occur.

Section 16 Power Supply Circuit
Section 16 Power Supply Circuit
This LSI incorporates an internal power supply step-down circuit. Use of this circuit enables the
internal power supply to be fixed at a constant level of approximately 3.0 V, independently of the
voltage of the power supply connected to the external VCC pin. As a result, the current consumed
when an external power supply is used at 3.0 V or above can be held down to virtually the same
low level as when used at approximately 3.0 V. If the external power supply is 3.0 V or below, the
internal voltage will be practically the same as the external voltage. It is, of course, also possible to
use the same level of external power supply voltage and internal power supply voltage without
using the internal power supply step-down circuit.
16.1
When Using Internal Power Supply Step-Down Circuit
Connect the external power supply to the VCC pin, and connect a capacitance of approximately 0.1
µF between VCL and VSS, as shown in figure 16.1. The internal step-down circuit is made effective
simply by adding this external circuit. In the external circuit interface, the external power supply
voltage connected to VCC and the GND potential connected to VSS are the reference levels. For
example, for port input/output levels, the VCC level is the reference for the high level, and the VSS
level is that for the low level. The A/D converter analog power supply is not affected by the
internal step-down circuit.

When Not Using Internal Power Supply Step-Down Circuit
When the internal power supply step-down circuit is not used, connect the external power supply
to the VCL pin and VCC pin, as shown in figure 16.2. The external power supply is then input directly
to the internal power supply. The permissible range for the power supply voltage is 3.0 V to 3.6 V.
Operation cannot be guaranteed if a voltage outside this range (less than 3.0 V or more than 3.6 V)
is input.

Notes: 1. This voltage should be used when the falling and rising voltage detection function is
used.
2. Select the low-voltage reset 2 when only the low-voltage detection reset is used.
3. When the power-supply voltage (Vcc) falls below VLVDRmin = 1.0 V and then rises, a reset
may not occur. Therefore sufficient evaluation is required.

Notes: 1. This voltage should be used when the falling and rising voltage detection function is
used.
2. Select the low-voltage reset 2 when only the low-voltage detection reset is used.
3. When the power-supply voltage (Vcc) falls below VLVDRmin = 1.0 V and then rises, a reset
may not occur. Therefore sufficient evaluation is required.

Notes: 1. The number of states in cases where the instruction code and its operands are located
in on-chip memory is shown here. For other cases see Appendix A.3, Number of
Execution States.
2. n is the value set in register R4L or R4.
(1) Set to 1 when a carry or borrow occurs at bit 11; otherwise cleared to 0.
(2) Set to 1 when a carry or borrow occurs at bit 27; otherwise cleared to 0.
(3) Retains its previous value when the result is zero; otherwise cleared to 0.
(4) Set to 1 when the adjustment produces a carry; otherwise retains its previous value.
(5) The number of states required for execution of an instruction that transfers data in
synchronization with the E clock is variable.
(6) Set to 1 when the divisor is negative; otherwise cleared to 0.
(7) Set to 1 when the divisor is zero; otherwise cleared to 0.
(8) Set to 1 when the quotient is negative; otherwise cleared to 0.

A.3
Number of Execution States
The status of execution for each instruction of the H8/300H CPU and the method of calculating
the number of states required for instruction execution are shown below. Table A.4 shows the
number of cycles of each type occurring in each instruction, such as instruction fetch and data
read/write. Table A.3 shows the number of states required for each cycle. The total number of
states required for execution of an instruction can be calculated by the following expression:
Execution states = I × SI + J × SJ + K × SK + L × SL + M × SM + N × SN
Examples: When instruction is fetched from on-chip ROM, and an on-chip RAM is accessed.
BSET #0, @FF00
From table A.4:
I = L = 2, J = K = M = N= 0
From table A.3:
SI = 2, SL = 2
Number of states required for execution = 2 × 2 + 2 × 2 = 8
When instruction is fetched from on-chip ROM, branch address is read from on-chip ROM, and
on-chip RAM is used for stack area.
JSR @@ 30
From table A.4:
I = 2, J = K = 1,
L=M=N=0
From table A.3:
SI = SJ = SK = 2
Number of states required for execution = 2 × 2 + 1 × 2+ 1 × 2 = 8

When using the on-chip emulator (E7, E8) for H8/36014
program development and debugging, the following
restrictions must be noted.
1. The NMI pin is reserved for the E7 or E8, and cannot be
used.
2. Area H'7000 to H'7FFF is used by the E7 or E8, and is not
available to the user.
4. When the E7 or E8 is used, address breaks can be set as
either available to the user or for use by the E7 or E8. If
address breaks are set as being used by the E7 or E8, the
address break control registers must not be accessed.
5. When the E7 or E8 is used, NMI is an input/output pin
(open-drain in output mode).
6. Use channel 1 of the SCI3 (P21/RXD, P22/TXD) in onboard programming mode by boot mode.
Note has been deleted.
