Open (when using an external clock).
Notes 1: After system is released from reset, port P5 is in a input mode (direction register FR0 = 00002)
2: When the P00 –P03 and P1 0–P1 3 are connected to VSS, turn off
their pull-up transistors (register PU0i=“0”) and also invalidate the
key-on wakeup functions (register K0i=“0”) by software. When
these pins are connected to V SS while the key-on wakeup functions are left valid, the system fails to return from RAM back-up
state. When these pins are open, turn on their pull-up transistors
(register PU0i=“1”) by software, or set the output latch to “0.”
Be sure to select the key-on wakeup functions and the pull-up
functions with every two pins. If only one of the two pins for the
key-on wakeup function is used, turn on their pull-up transistors by
software and also disconnect the other pin. (i = 0, 1, 2, or 3.)

(Note when the output latch is set to “0” and pins are open)
● After system is released from reset, port is in a high-impedance state until it is set the output latch to “0” by software. Accordingly, the voltage
level of pins is undefined and the excess of the supply current may occur
while the port is in a high-impedance state.
● To set the output latch periodically by software is recommended because
value of output latch may change by noise or a program run away
(caused by noise).
Open or connect to VSS (Note 2)
(Note when connecting to VSS and VDD)
● Connect the unused pins to VSS and VDD using the thickest wire at the
shortest distance against noise.

(5) Stack registers (SKS) and stack pointer (SP)
Stack registers (SKs) are used to temporarily store the contents of
program counter (PC) just before branching until returning to the
original routine when;
• branching to an interrupt service routine (referred to as an interrupt service routine),
• performing a subroutine call, or
• executing the table reference instruction (TABP p).
Stack registers (SKs) are eight identical registers, so that subroutines can be nested up to 8 levels. However, one of stack registers
is used respectively when using an interrupt service routine and
when executing a table reference instruction. Accordingly, be careful not to over the stack when performing these operations
together. The contents of registers SKs are destroyed when 8 levels are exceeded.
The register SK nesting level is pointed automatically by 3-bit
stack pointer (SP). The contents of the stack pointer (SP) can be
transferred to register A with the TASP instruction.
Figure 5 shows the stack registers (SKs) structure.
Figure 6 shows the example of operation at subroutine call.
(6) Interrupt stack register (SDP)
Interrupt stack register (SDP) is a 1-stage register. When an interrupt occurs, this register (SDP) is used to temporarily store the
contents of data pointer, carry flag, skip flag, register A, and register B just before an interrupt until returning to the original routine.
Unlike the stack registers (SKs), this register (SDP) is not used
when executing the subroutine call instruction and the table reference instruction.
(7) Skip flag
Skip flag controls skip decision for the conditional skip instructions
and continuous described skip instructions. When an interrupt occurs, the contents of skip flag is stored automatically in the interrupt
stack register (SDP) and the skip condition is retained.

Stack pointer (SP) points “7” at reset or
returning from RAM back-up mode. It points “0”
by executing the first BM instruction, and the
contents of program counter is stored in SK0.
When the BM instruction is executed after eight
stack registers are used ((SP) = 7), (SP) = 0
and the contents of SK0 is destroyed.

(8) Program counter (PC)
Program counter (PC) is used to specify a ROM address (page and
address). It determines a sequence in which instructions stored in
ROM are read. It is a binary counter that increments the number of
instruction bytes each time an instruction is executed. However,
the value changes to a specified address when branch instructions,
subroutine call instructions, return instructions, or the table reference instruction (TABP p) is executed.
Program counter consists of PC H (most significant bit to bit 7)
which specifies to a ROM page and PCL (bits 6 to 0) which specifies an address within a page. After it reaches the last address
(address 127) of a page, it specifies address 0 of the next page
(Figure 7).
Make sure that the PCH does not specify after the last page of the
built-in ROM.

Data pointer (DP) is used to specify a RAM address and consists
of registers Z, X, and Y. Register Z specifies a RAM file group, register X specifies a file, and register Y specifies a RAM digit (Figure

Register Y is also used to specify the port D bit position.
When using port D, set the port D bit position to register Y certainly
and execute the SD, RD, or SZD instruction (Figure 9).

A part of page 1 (addresses 008016 to 00FF16) is reserved for interrupt addresses (Figure 11). When an interrupt occurs, the
address (interrupt address) corresponding to each interrupt is set
in the program counter, and the instruction at the interrupt address
is executed. When using an interrupt service routine, write the instruction generating the branch to that routine at an interrupt
address.
Page 2 (addresses 010016 to 017F16) is the special page for subroutine calls. Subroutines written in this page can be called from
any page with the 1-word instruction (BM). Subroutines extending
from page 2 to another page can also be called with the BM instruction when it starts on page 2.
ROM pattern (bits 7 to 0) of all addresses can be used as data areas with the TABP p instruction.

INTERRUPT FUNCTION
The interrupt type is a vectored interrupt branching to an individual
address (interrupt address) according to each interrupt source. An
interrupt occurs when the following 3 conditions are satisfied.
• An interrupt activated condition is satisfied (request flag = “1”)
• Interrupt enable bit is enabled (“1”)
• Interrupt enable flag is enabled (INTE = “1”)
Table 3 shows interrupt sources. (Refer to each interrupt request
flag for details of activated conditions.)
(1) Interrupt enable flag (INTE)
The interrupt enable flag (INTE) controls whether the every interrupt enable/disable. Interrupts are enabled when INTE flag is set to
“1” with the EI instruction and disabled when INTE flag is cleared to
“0” with the DI instruction. When any interrupt occurs, the INTE flag
is automatically cleared to “0,” so that other interrupts are disabled
until the EI instruction is executed.

(2) Interrupt enable bit
Use an interrupt enable bit of interrupt control registers V1 and V2
to select the corresponding interrupt or skip instruction.
Table 4 shows the interrupt request flag, interrupt enable bit and
skip instruction.
Table 5 shows the interrupt enable bit function.
(3) Interrupt request flag
When the activated condition for each interrupt is satisfied, the corresponding interrupt request flag is set to “1.” Each interrupt
request flag is cleared to “0” when either;
• an interrupt occurs, or
• the next instruction is skipped with a skip instruction.
Each interrupt request flag is set when the activated condition is
satisfied even if the interrupt is disabled by the INTE flag or its interrupt enable bit. Once set, the interrupt request flag retains set
until a clear condition is satisfied.
Accordingly, an interrupt occurs when the interrupt disable state is
released while the interrupt request flag is set.
If more than one interrupt request flag is set when the interrupt disable state is released, the interrupt priority level is as follows
shown in Table 3.

(4) Internal state during an interrupt
The internal state of the microcomputer during an interrupt is as follows (Figure 14).
• Program counter (PC)
An interrupt address is set in program counter. The address to be
executed when returning to the main routine is automatically
stored in the stack register (SK).
• Interrupt enable flag (INTE)
INTE flag is cleared to “0” so that interrupts are disabled.
• Interrupt request flag
Only the request flag for the current interrupt source is cleared to
“0.”
• Data pointer, carry flag, skip flag, registers A and B
The contents of these registers and flags are stored automatically
in the interrupt stack register (SDP).
(5) Interrupt processing
When an interrupt occurs, a program at an interrupt address is executed after branching a data store sequence to stack register.
Write the branch instruction to an interrupt service routine at an interrupt address.
Use the RTI instruction to return from an interrupt service routine.
Interrupt enabled by executing the EI instruction is performed after
executing 1 instruction (just after the next instruction is executed).
Accordingly, when the EI instruction is executed just before the RTI
instruction, interrupts are enabled after returning the main routine.
(Refer to Figure 13)

(7) Interrupt sequence
Interrupts only occur when the respective INTE flag, interrupt enable bits (V10–V13 and V20 –V23 ), and interrupt request flag are
“1.” The interrupt actually occurs 2 to 3 machine cycles after the
cycle in which all three conditions are satisfied. The interrupt oc-
curs after 3 machine cycles only when the three interrupt conditions are satisfied on execution of other than one-cycle instructions
(Refer to Figure 16).

EXTERNAL INTERRUPTS
The 4513/4514 Group has two external interrupts (external 0 and
external 1). An external interrupt request occurs when a valid
waveform is input to an interrupt input pin (edge detection).
The external interrupts can be controlled with the interrupt control
registers I1 and I2.

(1) External 0 interrupt request flag (EXF0)
(2) External 1 interrupt request flag (EXF1)
External 0 interrupt request flag (EXF0) is set to “1” when a valid
waveform is input to P30/INT0 pin.
The valid waveforms causing the interrupt must be retained at their
level for 4 clock cycles or more of the system clock (Refer to Figure
16).
The state of EXF0 flag can be examined with the skip instruction
(SNZ0). Use the interrupt control register V1 to select the interrupt
or the skip instruction. The EXF0 flag is cleared to “0” when an interrupt occurs or when the next instruction is skipped with the skip
instruction.
The P30/INT0 pin need not be selected the external interrupt input
INT0 function or the normal I/O port P30 function. However, the
EXF0 flag is set to “1” when a valid waveform is input even if it is
used as an I/O port P30.
External 1 interrupt request flag (EXF1) is set to “1” when a valid
waveform is input to P31/INT1 pin.
The valid waveforms causing the interrupt must be retained at their
level for 4 clock cycles or more of the system clock (Refer to Figure
16).
The state of EXF1 flag can be examined with the skip instruction
(SNZ1). Use the interrupt control register V1 to select the interrupt
or the skip instruction. The EXF1 flag is cleared to “0” when an interrupt occurs or when the next instruction is skipped with the skip
instruction.
The P31/INT1 pin need not be selected the external interrupt input
INT1 function or the normal I/O port P3 1 function. However, the
EXF1 flag is set to “1” when a valid waveform is input even if it is
used as an I/O port P31.
• External 0 interrupt activated condition
External 0 interrupt activated condition is satisfied when a valid
waveform is input to P30/INT0 pin.
The valid waveform can be selected from rising waveform, falling
waveform or both rising and falling waveforms. An example of
how to use the external 0 interrupt is as follows.
• External 1 interrupt activated condition
External 1 interrupt activated condition is satisfied when a valid
waveform is input to P31/INT1 pin.
The valid waveform can be selected from rising waveform, falling
waveform or both rising and falling waveforms. An example of
how to use the external 1 interrupt is as follows.
➀ Select the valid waveform with the bits 1 and 2 of register I1.
➁ Clear the EXF0 flag to “0” with the SNZ0 instruction.
➂ Set the NOP instruction for the case when a skip is performed
with the SNZ0 instruction.
➃ Set both the external 0 interrupt enable bit (V10) and the INTE
flag to “1.”
➀ Select the valid waveform with the bits 1 and 2 of register I2.
➁ Clear the EXF1 flag to “0” with the SNZ1 instruction.
➂ Set the NOP instruction for the case when a skip is performed
with the SNZ1 instruction.
➃ Set both the external 1 interrupt enable bit (V11) and the INTE
flag to “1.”
The external 0 interrupt is now enabled. Now when a valid waveform is input to the P30/INT0 pin, the EXF0 flag is set to “1” and the
external 0 interrupt occurs.
The external 1 interrupt is now enabled. Now when a valid waveform is input to the P31/INT1 pin, the EXF1 flag is set to “1” and the
external 1 interrupt occurs.

TIMERS
The 4513/4514 Group has the programmable timers.
• Programmable timer
The programmable timer has a reload register and enables the
frequency dividing ratio to be set. It is decremented from a setting
value n. When it underflows (count to n + 1), a timer interrupt request flag is set to “1,” new data is loaded from the reload
register, and count continues (auto-reload function).
• Fixed dividing frequency timer
The fixed dividing frequency timer has the fixed frequency dividing ratio (n). An interrupt request flag is set to “1” after every n
count of a count pulse.

timer 2. Set the contents of this register through register A with
the TW2A instruction. The TAW2 instruction can be used to transfer the contents of register W2 to register A.
• Timer control register W3
Register W3 controls the count operation and count source of
timer 3 and the selection of count start synchronous circuit. Set
the contents of this register through register A with the TW3A instruction. The TAW3 instruction can be used to transfer the
contents of register W3 to register A.
• Timer control register W4
Register W4 controls the count operation and count source of
timer 4. Set the contents of this register through register A with
the TW4A instruction. The TAW4 instruction can be used to transfer the contents of register W4 to register A.
• Timer control register W6
Register W6 controls the D 6/CNTR0 pin and D 7 /CNTR1 functions, the selection and operation of the CNTR0 and CNTR1
output. Set the contents of this register through register A with
the TW6A instruction. The TAW6 instruction can be used to transfer the contents of register W6 to register A.
Prescaler is a frequency divider. Its frequency dividing ratio can be
selected. The count source of prescaler is the instruction clock.
Use the bit 2 of register W1 to select the prescaler dividing ratio
and the bit 3 to start and stop its operation. Prescaler is initialized,
and the output signal (ORCLK) stops when the bit 3 of register W1
is cleared to “0.”
(4) Timer 1 (interrupt function)
Timer 1 is an 8-bit binary down counter with the timer 1 reload register (R1). Data can be set simultaneously in timer 1 and the reload
register (R1) with the T1AB instruction. Data can be written to reload register (R1) with the TR1AB instruction.
When writing data to reload register R1 with the TR1AB instruction,
the downcount after the underflow is started from the setting value
of reload register R1.
Timer 1 starts counting after the following process;
➀ set data in timer 1, and
➁ set the bit 1 of register W1 to “1.”
However, P30/INT0 pin input can be used as the start trigger for
timer 1 count operation by setting the bit 0 of register W1 to “1.”
Once count is started, when timer 1 underflows (the next count
pulse is input after the contents of timer 1 becomes “0”), the timer
1 interrupt request flag (T1F) is set to “1,” new data is loaded from
reload register R1, and count continues (auto-reload function).
When a value set in reload register R1 is n, timer 1 divides the
count source signal by n + 1 (n = 0 to 255).
Data can be read from timer 1 with the TAB1 instruction. When
reading the data, stop the counter and then execute the TAB1 instruction. Timer 1 underflow signal divided by 2 can be output from
D6/CNTR0 pin.
(2) Precautions
Note the following for the use of timers.
• Prescaler
Stop the prescaler operation to change its frequency dividing ratio.
• Count source
Stop timer 1, 2, 3, or 4 counting to change its count source.
• Reading the count value
Stop timer 1, 2, 3, or 4 counting and then execute the TAB1,
TAB2, TAB3, or TAB4 instruction to read its data.
• Writing to reload registers R1 and R3
When writing data to reload registers R1 or R3 while timer 1 or
timer 3 is operating, avoid a timing when timer 1 or timer 3
underflows.
(5) Timer 2 (interrupt function)
Timer 2 is an 8-bit binary down counter with the timer 2 reload register (R2). Data can be set simultaneously in timer 2 and the reload
register (R2) with the T2AB instruction.
Timer 2 starts counting after the following process;
➀ set data in timer 2,
➁ select the count source with the bits 0 and 1 of register W2, and
➂ set the bit 3 of register W2 to “1.”
Once count is started, when timer 2 underflows (the next count
pulse is input after the contents of timer 2 becomes “0”), the timer
2 interrupt request flag (T2F) is set to “1,” new data is loaded from
reload register R2, and count continues (auto-reload function).
When a value set in reload register R2 is n, timer 2 divides the
count source signal by n + 1 (n = 0 to 255).
Data can be read from timer 2 with the TAB2 instruction. When
reading the data, stop the counter and then execute the TAB2 instruction. The output from D 6 /CNTR0 pin by timer 2 underflow
signal divided by 2 can be controlled.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
(6) Timer 3 (interrupt function)
(8) Timer I/O pin (D6/CNTR0, D7/CNTR1)
Timer 3 is an 8-bit binary down counter with the timer 3 reload register (R3). Data can be set simultaneously in timer 3 and the reload
register (R3) with the T3AB instruction. Data can be written to reload register (R3) with the TR3AB instruction.
When writing data to reload register R3 with the TR3AB instruction,
the downcount after the underflow is started from the setting value
of reload register R3.
Timer 3 starts counting after the following process;
➀ set data in timer 3,
➁ select the count source with the bits 0 and 1 of register W3, and
➂ set the bit 3 of register W3 to “1.”
However, P31/INT1 pin input can be used as the start trigger for
timer 3 count operation by setting the bit 2 of register W3 to “1.”
Once count is started, when timer 3 underflows (the next count
pulse is input after the contents of timer 3 becomes “0”), the timer
3 interrupt request flag (T3F) is set to “1,” new data is loaded from
reload register R3, and count continues (auto-reload function).
When a value set in reload register R3 is n, timer 3 divides the
count source signal by n + 1 (n = 0 to 255).
Data can be read from timer 3 with the TAB3 instruction. When
reading the data, stop the counter and then execute the TAB3 instruction. Timer 3 underflow signal divided by 2 can be output from
D7/CNTR1 pin.
D6/CNTR0 pin has functions to input the timer 2 count source, and
to output the timer 1 and timer 2 underflow signals divided by 2.
D7/CNTR1 pin has functions to input the timer 4 count source, and
to output the timer 3 and timer 4 underflow signals divided by 2.
The selection of D6/CNTR0 pin function can be controlled with the
bit 0 of register W6. The selection of D7/CNTR1 pin function can be
controlled with the bit 2 of register W6.
The following signals can be selected for the CNTR0 output signal
with the bit 1 of register W6.
• timer 1 underflow signal divided by 2
• the signal of AND operation between timer 1 underflow signal divided by 2 and timer 2 underflow signal divide by 2
The following signals can be selected for the CNTR1 output signal
with the bit 3 of register W6.
• timer 3 underflow signal divided by 2
• the signal of AND operation between timer 3 underflow signal divided by 2 and timer 4 underflow signal divide by 2
Timer 2 counts the rising waveform of CNTR0 input when the
CNTR0 input is selected as the count source.
Timer 4 counts the rising waveform of CNTR1 input when the
CNTR1 input is selected as the count source.
(7) Timer 4 (interrupt function)
Each timer interrupt request flag is set to “1” when each timer
underflows. The state of these flags can be examined with the skip
instructions (SNZT1, SNZT2, SNZT3, and SNZT4).
Use the interrupt control registers V1, V2 to select an interrupt or a
skip instruction.
An interrupt request flag is cleared to “0” when an interrupt occurs
or when the next instruction is skipped with a skip instruction.
Timer 4 is an 8-bit binary down counter with the timer 4 reload register (R4). Data can be set simultaneously in timer 4 and the reload
register (R4) with the T4AB instruction.
Timer 4 starts counting after the following process;
➀ set data in timer 4,
➁ select the count source with the bits 0 and 1 of register W4, and
➂ set the bit 3 of register W4 to “1.”
Once count is started, when timer 4 underflows (the next count
pulse is input after the contents of timer 4 becomes “0”), the timer
4 interrupt request flag (T4F) is set to “1,” new data is loaded from
reload register R4, and count continues (auto-reload function).
When a value set in reload register R4 is n, timer 4 divides the
count source signal by n + 1 (n = 0 to 255).
Data can be read from timer 4 with the TAB4 instruction. When
reading the data, stop the counter and then execute the TAB4 instruction. The output from D 7 /CNTR1 pin by timer 4 underflow
signal divided by 2 can be controlled.
32
(9) Timer interrupt request flags (T1F, T2F,
T3F, and T4F)
(10) Count start synchronization circuit (timer
1, timer 3)
Each timer 1 and timer 3 has the count start synchronization circuit
which synchronize P30/INT0 pin and P31/INT1 pin, respectively,
and can start the timer count operation.
Timer 1 count start synchronization circuit function is selected by
setting the bit 0 of register W1 to “1.” The control by P30/INT0 pin
input can be performed by setting the bit 0 of register I1 to “1.”
P30/INT0 pin input level can be selected by the bit 2 of register I1
as follows;
• I12 = “0”: The count start synchronizes the “L” level of P30/INT0 pin
• I12 = “1”: The count start synchronizes the “H” level of P30/INT0 pin
Timer 3 count start synchronization circuit function is selected by
setting the bit 2 of register W3 to “1.” The control by P31/INT1 pin
input can be performed by setting the bit 0 of register I2 to “1.”
P31/INT1 pin input level can be selected by the bit 2 of register I2
as follows;
• I22 = “0”: The count start synchronizes the “L” level of P31/INT1 pin
• I22 = “1”: The count start synchronizes the “H” level of P31/INT1 pin
When timer 1 and timer 3 count start synchronization circuits are
used, the count start synchronization circuits are set, the count
source is input to each timer by inputting valid levels to P30/INT0
pin and P31/INT1 pin. Once set, the count start synchronization circuit is cleared by clearing the bit I10 or I20 to “0” or reset.

SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
WATCHDOG TIMER
Watchdog timer provides a method to reset the system when a program runs wild. Watchdog timer consists of a 16-bit timer (WDT),
watchdog timer enable flag (WEF), and watchdog timer flags
(WDF1, WDF2).
The timer WDT downcounts the instruction clocks as the count
source. The underflow signal is generated when the count value
reaches “000016.” This underflow signal can be used as the timer 2
count source.
When the WRST instruction is executed after system is released
from reset, the WEF flag is set to “1”. At this time, the watchdog
timer starts operating.
When the count value of timer WDT reaches “BFFF16” or “3FFF16,”
the WDF1 flag is set to “1.” If the WRST instruction is never executed while timer WDT counts 32767, WDF2 flag is set to “1,” and
the RESET pin outputs “L” level to reset the microcomputer. Execute the WRST instruction at each period of 32766 machine cycle
or less by software when using watchdog timer to keep the microcomputer operating normally.
To prevent the WDT stopping in the event of misoperation, WEF
flag is designed not to initialize once the WRST instruction has
been executed. Note also that, if the WRST instruction is never executed, the watchdog timer does not start.

If WDF2 flag is set to “1” at the same time that the microcomputer
enters the RAM back-up state, system reset may be performed.
When using the watchdog timer and the RAM back-up mode, initialize the WDF1 flag with the WRST instruction just before the
microcomputer enters the RAM back-up state (refer to Figure 21)

SERIAL I/O
Table 11 Serial I/O pins
The 4513/4514 Group has a built-in clock synchronous serial I/O
which can serially transmit or receive 8-bit data.
Serial I/O consists of;
• serial I/O register SI
• serial I/O mode register J1
• serial I/O transmission/reception completion flag (SIOF)
• serial I/O counter
Registers A and B are used to perform data transfer with internal
CPU, and the serial I/O pins are used for external data transfer.
The pin functions of the serial I/O pins can be set with the register
J1.

Fig. 23 Serial I/O register state when transferring
(1) Serial I/O register SI
(3) Serial I/O start instruction (SST)
Serial I/O register SI is the 8-bit data transfer serial/parallel conversion register. Data can be set to register SI through registers A and
B with the TSIAB instruction. The contents of register A is transmitted to the low-order 4 bits of register SI, and the contents of
register B is transmitted to the high-order 4 bits of register SI.
During transmission, each bit data is transmitted LSB first from the
lowermost bit (bit 0) of register SI, and during reception, each bit
data is received LSB first to register SI starting from the topmost bit
(bit 7).
When register SI is used as a work register without using serial I/O,
pull up the SCK pin or set the pin function to an input port P20.
When the SST instruction is executed, the SIOF flag is cleared to
“0” and then serial I/O transmission/reception is started.
(4) Serial I/O mode register J1
Register J1 controls the synchronous clock, P2 0/S CK, P21 /SOUT
and P22/SIN pin function. Set the contents of this register through
register A with the TJ1A instruction. The TAJ1 instruction can be
used to transfer the contents of register J1 to register A.
(2) Serial I/O transmission/reception
completion flag (SIOF)
Serial I/O transmission/reception completion flag (SIOF) is set to
“1” when serial data transmission or reception completes. The
state of SIOF flag can be examined with the skip instruction
(SNZSI). Use the interrupt control register V2 to select the interrupt or the skip instruction.
The SIOF flag is cleared to “0” when the interrupt occurs or when
the next instruction is skipped with the skip instruction.

input. (Unlike an internal clock, an external clock is not stopped
when serial transfer is completed.) However, the SIOF flag is set to
“1” when the clock is counted 8 times after executing the SST instruction. Be sure to set the initial level of the external clock to “H.”

The value of the comparator register is retained even when the mode is switched to the A-D conversion
mode (Q23=0) because it is separated from the successive comparison register (AD). Also, the resolution in
the comparator mode is 8 bits because the comparator register consists of 8 bits.
3: The 4513 Group does not have ports P40/AIN4–P43/AIN7 and the IAP4 and OP4A instructions.

(1) Operating at A-D conversion mode
(4) A-D conversion start instruction (ADST)
The A-D conversion mode is set by setting the bit 3 of register Q2 to “0.”
A-D conversion starts when the ADST instruction is executed. The
conversion result is automatically stored in the register AD.
(2) Successive comparison register AD
Register AD stores the A-D conversion result of an analog input in
10-bit digital data format. The contents of the high-order 8 bits of
this register can be stored in register B and register A with the
TABAD instruction. The contents of the low-order 2 bits of this register can be stored into the high-order 2 bits of register A with the
TALA instruction. However, do not execute this instruction during AD conversion.
When the contents of register AD is n, the logic value of the comparison voltage Vref generated from the built-in DA converter can
be obtained with the reference voltage VDD by the following formula:
Logic value of comparison voltage Vref
Vref =
V DD
✕n
1024
n: The value of register AD (n = 0 to 1023)
(3) A-D conversion completion flag (ADF)
A-D conversion completion flag (ADF) is set to “1” when A-D conversion completes. The state of ADF flag can be examined with the
skip instruction (SNZAD). Use the interrupt control register V2 to
select the interrupt or the skip instruction.
The ADF flag is cleared to “0” when the interrupt occurs or when
the next instruction is skipped with the skip instruction.
40
(5) A-D control register Q1
Register Q1 is used to select one of analog input pins. The 4513
Group does not have AIN4–AIN7. Accordingly, do not select these
pins with register Q1.
(6) A-D control register Q2
Register Q2 is used to select the pin function of P40 /A IN4, P41/
AIN5 , P4 2/A IN6, and P4 3 /A IN7. The A-D conversion mode is selected when the bit 3 of register Q2 is “0,” and the comparator
mode is selected when the bit 3 of register Q2 is “1.” After set this
register, select the analog input with register Q1.
Even when register Q2 is used to set the pins for analog input,
P40/AIN4–P43 /AIN7 continue to function as P40–P4 3 I/O. Accordingly, when any of them are used as I/O port P4 and others are
used as analog input pins, make sure to set the outputs of pins that
are set for analog input to “1.” Also, for the port input, the port input
function of the pin functions as analog input is undefined.

(7) Operation description
A-D conversion is started with the A-D conversion start instruction
(ADST). The internal operation during A-D conversion is as follows:
➀ When A-D conversion starts, the register AD is cleared to
“00016.”
➁ Next, the topmost bit of the register AD is set to “1,” and the
comparison voltage Vref is compared with the analog input voltage VIN.
➂ When the comparison result is V ref < VIN, the topmost bit of the
register AD remains set to “1.” When the comparison result is
Vref > VIN, it is cleared to “0.”
The 4513/4514 Group repeats this operation to the lowermost bit of
the register AD to convert an analog value to a digital value. A-D
conversion stops after 62 machine cycles (46.5 µs when f(XIN) =
4.0 MHz in high-speed mode) from the start, and the conversion result is stored in the register AD. An A-D interrupt activated condition
is satisfied and the ADF flag is set to “1” as soon as A-D conversion
completes (Figure 27).

(9) How to use A-D conversion
How to use A-D conversion is explained using as example in which
the analog input from P40/AIN4 pin is A-D converted, and the highorder 4 bits of the converted data are stored in address M(Z, X, Y)
= (0, 0, 0), the middle-order 4 bits in address M(Z, X, Y) = (0, 0, 1),
and the low-order 2 bits in address M(Z, X, Y) = (0, 0, 2) of RAM.
The A-D interrupt is not used in this example.
➀ After selecting the AIN4 pin function with the bit 0 of the register
Q2, select AIN4 pin and A-D conversion mode with the register
Q1 (refer to Figure 28).
➁ Execute the ADST instruction and start A-D conversion.
➂ Examine the state of ADF flag with the SNZAD instruction to determine the end of A-D conversion.
➃ Transfer the low-order 2 bits of converted data to the high-order
2 bits of register A (TALA instruction).
➄ Transfer the contents of register A to M (Z, X, Y) = (0, 0, 2).
➅ Transfer the high-order 8 bits of converted data to registers A
and B (TABAD instruction).
➆ Transfer the contents of register A to M (Z, X, Y) = (0, 0, 1).
➇ Transfer the contents of register B to register A, and then, store
into M(Z, X, Y) = (0, 0, 0).

(10) Operation at comparator mode
(12) Comparison result store flag (ADF)
The A-D converter is set to comparator mode by setting bit 3 of the
register Q2 to “1.”
Below, the operation at comparator mode is described.
In comparator mode, the ADF flag, which shows completion of A-D
conversion, stores the results of comparing the analog input voltage with the comparison voltage. When the analog input voltage is
lower than the comparison voltage, the ADF flag is set to “1.” The
state of ADF flag can be examined with the skip instruction
(SNZAD). Use the interrupt control register V2 to select the interrupt or the skip instruction.
The ADF flag is cleared to “0” when the interrupt occurs or when
the next instruction is skipped with the skip instruction.
(11) Comparator register
In comparator mode, the built-in DA comparator is connected to the
comparator register as a register for setting comparison voltages.
The contents of register B is stored in the high-order 4 bits of the
comparator register and the contents of register A is stored in the
low-order 4 bits of the comparator register with the TADAB instruction.
When changing from A-D conversion mode to comparator mode,
the result of A-D conversion (register AD) is undefined.
However, because the comparator register is separated from register AD, the value is retained even when changing from comparator
mode to A-D conversion mode. Note that the comparator register
can be written and read at only comparator mode.
If the value in the comparator register is n, the logic value of comparison voltage Vref generated by the built-in DA converter can be
determined from the following formula:
Logic value of comparison voltage V ref
Vref =
VDD
256
✕n
n: The value of register AD (n = 0 to 255)
(13) Comparator operation start instruction
(ADST instruction)
In comparator mode, executing ADST starts the comparator operating.
The comparator stops 8 machine cycles after it has started (6 µs at
f(XIN) = 4.0 MHz in high-speed mode). When the analog input voltage is lower than the comparison voltage, the ADF flag is set to “1.”
(14) Notes for the use of A-D conversion 1
Note the following when using the analog input pins also for I/O
port P4 functions:
• Even when P40/AIN4–P43/AIN7 are set to pins for analog input,
they continue to function as P40–P43 I/O. Accordingly, when any
of them are used as I/O port P4 and others are used as analog
input pins, make sure to set the outputs of pins that are set for
analog input to “1.” Also, the port input function of the pin functions as an analog input is undefined.
• TALA instruction
When the TALA instruction is executed, the low-order 2 bits of
register AD is transferred to the high-order 2 bits of register A, simultaneously, the low-order 2 bits of register A is “0.”

(15) Notes for the use of A-D conversion 2
(16) Definition of A-D converter accuracy
Do not change the operating mode (both A-D conversion mode and
comparator mode) of A-D converter with bit 3 of register Q2 while
A-D converter is operating.
When the operating mode of A-D converter is changed from the
comparator mode to A-D conversion mode with the bit 3 of register
Q2, note the following;
• Clear bit 2 of register V2 to “0” to change the operating mode of
the A-D converter from the comparator mode to A-D conversion
mode with the bit 3 of register Q2.
• The A-D conversion completion flag (ADF) may be set when the
operating mode of the A-D converter is changed from the comparator mode to the A-D conversion mode. Accordingly, set a
value to register Q2, and execute the SNZAD instruction to clear
the ADF flag.
The A-D conversion accuracy is defined below (refer to Figure 30).
• Relative accuracy
➀ Zero transition voltage (V0T)
This means an analog input voltage when the actual A-D conversion output data changes from “0” to “1.”
➁ Full-scale transition voltage (VFST)
This means an analog input voltage when the actual A-D conversion output data changes from “1023” to ”1022.”
➂ Linearity error
This means a deviation from the line between V0T and VFST of
a converted value between V0T and VFST.
➃ Differential non-linearity error
This means a deviation from the input potential difference required to change a converter value between V0T and VFST by 1
LSB at the relative accuracy.
• Absolute accuracy
This means a deviation from the ideal characteristics between 0
to VDD of actual A-D conversion characteristics.

Notes 1: “R” represents read enabled, and “W” represents write enabled.
2: Bits 0 and 1 of register Q3 can be only read.
(1) Voltage comparator control register Q3
(3) Precautions
Register Q3 controls the function of the voltage comparator.
The function of the voltage comparator CMP0 becomes valid by
setting bit 2 of register Q3 to “1,” and becomes invalid by setting bit
2 of register Q3 to ”0.” The comparison result of the voltage comparator CMP0 is stored into bit 0 of register Q3.
The function of the voltage comparator CMP1 becomes valid by
setting bit 3 of register Q3 to “1,” and becomes invalid by setting bit
3 of register Q3 to ”0.” The comparison result of the voltage comparator CMP1 is stored into bit 1 of register Q3.
When the voltage comparator is used, note the following;
• Voltage comparator function
When the voltage comparator function is valid with the voltage
comparator control register Q3, it is operating even in the RAM
back-up mode. Accordingly, be careful about such state because
it causes the increase of the operation current in the RAM backup mode.
In order to reduce the operation current in the RAM back-up
mode, invalidate (bits 2 and 3 of register Q3 = “0”) the voltage
comparator function by software before the POF instruction is
executed.
Also, while the voltage comparator function is valid, current is always consumed by voltage comparator. On the system required
for the low-power dissipation, invalidate the voltage comparator
by software when it is unused.
(2) Operation description of voltage
comparator
The voltage comparator function becomes valid by setting each
control bit of register Q3 to “1” and compares the voltage of the input pin. The comparison result is stored into each comparison
result store bit of register Q3.
The comparison result is as follows;
• When CMP0- > CMP0+, Q30 = “0”
When CMP0- < CMP0+, Q30 = “1”
• When CMP1- > CMP1+, Q31 = “0”
When CMP1- < CMP1+, Q31 = “1”
46
• Register Q3
Bits 0 and 1 of register Q3 can be only read. Note that they cannot be written.
• Reading the comparison result of voltage comparator
Read the voltage comparator comparison result from register Q3
after the voltage comparator response time (max. 20 µ s) is
passed from the voltage comparator function becomes valid.

RAM BACK-UP MODE
SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
Table 20 Functions and states retained at RAM back-up
The 4513/4514 Group has the RAM back-up mode.
When the EPOF and POF instructions are executed continuously,
system enters the RAM back-up state. The POF instruction is
equal to the NOP instruction when the EPOF instruction is not executed before the POF instruction.
As oscillation stops retaining RAM, the function of reset circuit and
states at RAM back-up mode, current dissipation can be reduced
without losing the contents of RAM. Table 20 shows the function
and states retained at RAM back-up. Figure 38 shows the state
transition.

(4) Return signal
An external wakeup signal is used to return from the RAM back-up
mode because the oscillation is stopped. Table 21 shows the return
condition for each return source.
(5) Ports P0 and P1 control registers
• Key-on wakeup control register K0
Register K0 controls the ports P0 and P1 key-on wakeup function. Set the contents of this register through register A with the
TK0A instruction. In addition, the TAK0 instruction can be used to
transfer the contents of register K0 to register A.
• Pull-up control register PU0
Register PU0 controls the ON/OFF of the ports P0 and P1 pull-up
transistor. Set the contents of this register through register A with
the TPU0A instruction. In addition, the TAPU0 instruction can be
used to transfer the contents of register PU0 to register A.

Clock signal f(XIN) is obtained by externally connecting a ceramic
resonator.
Connect this external circuit to pins X IN and XOUT at the shortest
distance. A feedback resistor is built in between pins XIN and XOUT.
When an external clock signal is input, connect the clock source to
XIN and leave XOUT open. When using an external clock, the maximum value of external clock oscillating frequency is shown in Table
24.

LIST OF PRECAUTIONS
➀Noise and latch-up prevention
Connect a capacitor on the following condition to prevent noise
and latch-up;
• connect a bypass capacitor (approx. 0.1 µF) between pins VDD
and VSS at the shortest distance,
• equalize its wiring in width and length, and
• use relatively thick wire.
In the One Time PROM version, CNVSS pin is also used as VPP
pin. Accordingly, when using this pin, connect this pin to VSS
through a resistor about 5 kΩ in series at the shortest distance.
➁Prescaler
Stop the prescaler operation to change its frequency dividing ratio.
➂Timer count source
Stop timer 1, 2, 3, or 4 counting to change its count source.
➃Reading the count value
Stop timer 1, 2, 3, or 4 counting and then execute the TAB1,
TAB2, TAB3, or TAB4 instruction to read its data.
SINGLE-CHIP 4-BIT CMOS MICROCOMPUTER
➆P31/INT1 pin
When the interrupt valid waveform of P31/INT1 pin is changed
with the bit 2 of register I2 in software, be careful about the following notes.
• Clear the bit 1 of register V1 to “0” before the interrupt valid waveform of P31/INT1 pin is changed with the bit 2 of register I2 (refer
to Figure 45➂).
• Depending on the input state of the P31/INT1 pin, the external 1
interrupt request flag (EXF1) may be set when the interrupt valid
waveform is changed. Accordingly, clear bit 2 of register I2 and
execute the SNZ1 instruction to clear the EXF1 flag after executing at least one instruction (refer to Figure 45➃).

➄Writing to reload registers R1 and R3
When writing data to reload registers R1 or R3 while timer 1 or
timer 3 is operating, avoid a timing when timer 1 or timer 3
underflows.
➅P30/INT0 pin
When the interrupt valid waveform of the P3 0 /INT0 pin is
changed with the bit 2 of register I1 in software, be careful about
the following notes.
• Clear the bit 0 of register V1 to “0” before the interrupt valid waveform of P30/INT0 pin is changed with the bit 2 of register I1 (refer
to Figure 44➀).
• Depending on the input state of the P30/INT0 pin, the external 0
interrupt request flag (EXF0) may be set when the interrupt valid
waveform is changed. Accordingly, clear bit 2 of register I1, and
execute the SNZ0 instruction to clear the EXF0 flag after executing at least one instruction (refer to Figure 44➁)

➉ A-D converter-1
When the operating mode of the A-D converter is changed from
the comparator mode to the A-D conversion mode with the bit 3
of register Q2 in a program, be careful about the following notes.
• Clear the bit 2 of register V2 to “0” to change the operating mode
of the A-D converter from the comparator mode to the A-D conversion mode with the bit 3 of register Q2 (refer to Figure 46➄).
• The A-D conversion completion flag (ADF) may be set when the
operating mode of the A-D converter is changed from the comparator mode to the A-D conversion mode. Accordingly, set a
value to register Q2, and execute the SNZAD instruction to clear
the ADF flag.
Do not change the operating mode (both A-D conversion mode
and comparator mode) of A-D converter with the bit 3 of register
Q2 during operating the A-D converter.

A-D converter-2
Each analog input pin is equipped with a capacitor which is used
to compare the analog voltage. Accordingly, when the analog
voltage is input from the circuit with high-impedance and, charge/
discharge noise is generated and the sufficient A-D accuracy
may not be obtained. Therefore, reduce the impedance or, connect a capacitor (0.01 µF to 1 µF) to analog input pins (Figure
47).
When the overvoltage applied to the A-D conversion circuit may
occur, connect an external circuit in order to keep the voltage
within the rated range as shown the Figure 48. In addition, test
the application products sufficiently.

AIN
POF instruction
Execute the POF instruction immediately after executing the
EPOF instruction to enter the RAM back-up.
Note that system cannot enter the RAM back-up state when executing only the POF instruction.
Be sure to disable interrupts by executing the DI instruction before executing the EPOF instruction.
Analog input pins
Note the following when using the analog input pins also for I/O
port P4 functions:
• Even when P40/AIN4–P43/AIN7 are set to pins for analog input,
they continue to function as P40–P43 I/O. Accordingly, when any
of them are used as I/O port P4 and others are used as analog
input pins, make sure to set the outputs of pins that are set for
analog input to “1.” Also, the port input function of the pin functions as an analog input is undefined.
• TALA instruction
When the TALA instruction is executed, the low-order 2 bits of
register AD is transferred to the high-order 2 bits of register A, simultaneously, the low-order 2 bits of register A is “0.”

Voltage comparator function
When the voltage comparator function is valid with the voltage
comparator control register Q3, it is operating even in the RAM
back-up mode. Accordingly, be careful about such state because
it causes the increase of the operation current in the RAM backup mode.
In order to reduce the operation current in the RAM back-up
mode, invalidate (bits 2 and 3 of register Q3 = “0”) the voltage
comparator function by software before the POF instruction is executed.
Also, while the voltage comparator function is valid, current is always consumed by voltage comparator. On the system required
for the low-power dissipation, invalidate the voltage comparator
when it is unused by software.

Note : The 4513/4514 Group just invalidates the next instruction when a skip is performed. The contents of program counter is not increased by 2. Accordingly, the number of cycles does not change even if skip is not performed. However, the cycle count becomes “1” if the TABP p, RT, or RTS instruction
is skipped.

–
Loads the value n in the immediate field to register A.
When the LA instructions are continuously coded and executed, only the first LA instruction is executed and
other LA instructions coded continuously are skipped.
–
–
Transfers bits 7 to 4 to register B and bits 3 to 0 to register A. These bits 7 to 0 are the ROM pattern in address (DR2 DR1 DR0 A3 A2 A1 A0)2 specified by registers A and D in page p.
When this instruction is executed, 1 stage of stack register is used.
–
–
Adds the contents of M(DP) to register A. Stores the result in register A. The contents of carry flag CY remains unchanged.
–
0/1 Adds the contents of M(DP) and carry flag CY to register A. Stores the result in register A and carry flag CY.
Overflow = 0
–
Adds the value n in the immediate field to register A.
The contents of carry flag CY remains unchanged.
Skips the next instruction when there is no overflow as the result of operation.
–
–
Takes the AND operation between the contents of register A and the contents of M(DP), and stores the result in register A.
–
–
Takes the OR operation between the contents of register A and the contents of M(DP), and stores the result
in register A.
–
1
Sets (1) to carry flag CY.
–
0
Clears (0) to carry flag CY.
(CY) = 0
–
Skips the next instruction when the contents of carry flag CY is “0.”
–
–
Stores the one’s complement for register A’s contents in register A.
–
0/1 Rotates 1 bit of the contents of register A including the contents of carry flag CY to the right.
–
–
Sets (1) the contents of bit j (bit specified by the value j in the immediate field) of M(DP).
–
–
Clears (0) the contents of bit j (bit specified by the value j in the immediate field) of M(DP).
(Mj(DP)) = 0
j = 0 to 3
–
Skips the next instruction when the contents of bit j (bit specified by the value j in the immediate field) of
M(DP) is “0.”
(A) = (M(DP))
–
Skips the next instruction when the contents of register A is equal to the contents of M(DP).
(A) = n
–
Skips the next instruction when the contents of register A is equal to the value n in the immediate field.

BUILT-IN PROM VERSION
In addition to the mask ROM versions, the 4513/4514 Group has
programmable ROM version software compatible with mask ROM.
The built-in PROM of One Time PROM version can be written to
and not be erased.
The built-in PROM versions have functions similar to those of the
mask ROM versions, but they have PROM mode that enables writing to built-in PROM.
Table 25 shows the product of built-in PROM version. Figure 49
and 50 show the pin configurations of built-in PROM versions.

(1) PROM mode
The built-in PROM version has a PROM mode in addition to a normal operation mode. The PROM mode is used to write to and read
from the built-in PROM.
In the PROM mode, the programming adapter can be used with a
general-purpose PROM programmer to write to or read from the
built-in PROM as if it were M5M27C256K. Programming adapters
are listed in Table 26.Contact addresses at the end of this sheet for
the appropriate PROM programmer.
• Writing and reading of built-in PROM
Programming voltage is 12.5 V. Write the program in the PROM
of the built-in PROM version as shown in Figure 51.
(2) Notes on handling
➀A high-voltage is used for writing. Take care that overvoltage is
not applied. Take care especially at turning on the power.
➁For the One Time PROM version shipped in blank, Mitsubishi
Electric corp. does not perform PROM writing test and screening
in the assembly process and following processes. In order to improve reliability after writing, performing writing and test
according to the flow shown in Figure 52 before using is recommended (Products shipped in blank: PROM contents is not
written in factory when shipped).
