BASIC FUNCTION BLOCKS
The M37733S4LHP has the same functions as the
M37733MHBXXXFP except for the following :
(1) The memory map is different.
(2) The processor mode is different.
(3) The reset circuit is different.
(4) Pulse output port mode of timer A is available.
(5) The function of ROM area modification is not available.
MEMORY
The 2048-byte area allocated to addresses from 8016 to 87F16 is the
built-in RAM. In addition to storing data, the RAM is used as stack
during a subroutine call or interrupts.
Peripheral devices such as I/O ports, A-D converter, serial I/O, timer,
and interrupt control registers are allocated to addresses from 016 to
7F16 .
A 256-byte direct page area can be allocated anywhere in bank 016
by using the direct page register (DPR). In the direct page addressing
mode, the memory in the direct page area can be accessed with two
words. Hence program steps can be reduced.
The memory map is shown in Figure 1. The address space has a
capacity of 16 Mbytes and is allocated to addresses from 016 to
FFFFFF16. The address space is divided by 64-Kbyte unit called bank.
The banks are numbered from 016 to FF16.
Built-in RAM and control registers for internal peripheral devices are
assigned to bank 016 .
Addresses FFD616 to FFFF16 are the RESET and interrupt vector
addresses and contain the interrupt vectors. Use ROM for memory
of this address.

Pulse output port mode
The pulse motor drive waveform can be output by using plural internal
timer A.
Figure 3 shows a block diagram for pulse output port mode. In the
pulse output port mode, two pairs of four-bit pulse output ports are
used. Whether using pulse output port or not can be selected by
waveform output selection bit (bit 0, bit 1) of waveform output mode
register (6216 address) shown in Figure 4. When bit 0 of waveform
output selection bit is set to “1”, RTP10, RTP11, RTP12, and RTP13
are used as pulse output ports, and when bit 1 of waveform output
selection bit is set to “1”, RTP00, RTP0 1, RTP0 2, and RTP03 are
used as pulse output ports. When bits 1 and 0 of waveform output
selection bit are set to “1”, RTP10, RTP11, RTP12, and RTP13, and
RTP00 , RTP01, RTP02, and RTP03 are used as pulse output ports.
The ports not used as pulse output ports can be used as normal
parallel ports, timer input/output or key input interrupt input.
In the pulse output port mode, set timers A0 and A2 to timer mode as
timers A0 and A2 are used. Figure 5 shows the bit configuration of
timer A0, A2 mode registers in pulse output port mode.
Data can be set in each bit of the pulse output data register
corresponding to four ports selected as pulse output ports. Figure 6
4
shows the bit configuration of the pulse output data register. The
contents of the pulse output data register 1 (low-order four bits of
1C16 address) corresponding to RTP1 0, RTP11, RTP1 2, and RTP13
is output to the ports each time the counter of timer A2 becomes
000016. The contents of the pulse output data register 0 (low-order
four bits of 1D16 address) corresponding to RTP00 , RTP01, RTP02,
and RTP03 is output to the ports each time the counter of timer A0
becomes 000016.
Figure 7 shows example of waveforms in pulse output port mode.
When “0” is written to a specified bit of the pulse output data register,
“L” level is output to the corresponding pulse output port when the
counter of corresponding timer becomes 000016, and when “1” is
written, “H” level is output to the pulse output port.
Pulse width modulation can be applied to each pulse output port.
Since pulse width modulation involves the use of timers A1 and A3,
activate these timers in pulse width modulation mode.

RTP10, RTP11, RTP12, and RTP13 are applied pulse width modulation
by timer A3 by setting the pulse width modulation selection bit by
timer A3 (bit 5) of the waveform output mode register to “1”.
RTP00, RTP01, RTP02, and RTP03 are applied pulse width modulation
by timer A1 by setting the pulse width modulation selection bit by
timer A1 (bit 4) of the waveform output mode register to “1”.
The contents of the pulse output data register 0 can be reversed and
output to pulse output ports RTP00 , RTP01, RTP0 2, and RTP03 by
the polarity selection bit (bit 3) of the waveform output mode register.
When the polarity selection bit is “0”, the contents of the pulse output
data register 0 is output unchangeably, and when “1”, the contents of
the pulse output data register 0 is reversed and output. When pulse
width modulation is applied, likewise the polarity reverse to pulse
width modulation can be selected by the polarity selection bit.

PROCESSOR MODE
• BYTE pin
The bits 0 of processor mode register 0 as shown in Figure 8 is used
to select which mode of microprocessor mode, and evaluation chip
mode.
Figure 9 shows functions of P00/A 0 to P47 pins in each mode.
The external memory area also changes when the mode changes.
Figure 10 shows the memory map for each mode.
The accessing of the external memory is affected by the BYTE pin,
the bit 2 (wait bit) of processor mode register 0, and bit 0 (wait selection
bit) of processor mode register 1.
When accessing the external memory, the level of the BYTE pin is
used to determine whether to use the data bus as 8-bit width or 16bit width.
The data bus width is 8 bits when the level of the BYTE pin is “H”,
and P20/A16 /D0 to P27/A23/D7 pins become the data I/O pins.
The data bus width is 16 bits when the level of the BYTE pin is “L”,
and both P20/A16 /D0 to P27/A23 /D7 pins and P10/A 8/D 8 to P17/A15 /
D15 pins become the data I/O pins.
When accessing the internal memory, the data bus width is always
16 bits regardless of the BYTE pin level.

• Wait bit
As shown in Figure 11, when the external memory area is accessed
with the processor mode register 0 (address 5E16) bit 2 (wait bit)
cleared to “0”, the access time can be extended compared with no
wait (the wait bit is “1”).
The access time is extended in two ways and this is selected with bit
0 (wait selection bit) of processor mode register 1 (address 5F16).
When this bit is “1”, the access time is 1.5 times compared to that for
no wait. When this bit is “0”, the access time is twice compared to
that for no wait.
At reset, the wait bit and the wait selection bit are “0”.
The accessing of internal memory area is performed in no wait mode
regardless of the wait bit.
The processor modes are described below.

Signal E is output from pin E and is “L” during the data/instruction
code read or data write term. When the internal memory area is read
_
or written, E can be fixed to “H” by setting the signal output disable
selection bit (bit 6 of oscillation circuit control register 0) to “1”.
P00/A0 to P07/A7 pins become address output pins.
P10/A8/D8 to P17/A15/D 15 pins have two functions depending on the
level of the BYTE pin.
When the BYTE pin level is “L”, P10/A8/D8 to P17/A15/D15 pins function
_
as an address
output pin while E is “H” and as an odd address data
_
I/O pin while E is “L”. However,
if an internal memory is read, external
_
data is ignored while E is “L”.
When the BYTE pin level is “H”, P10/A8/D8 to P17/A15/D15 pins function
as an address output pin.
When the BYTE pin level is “L”, P20/A16/D0 to P2 7/A23/D7 pins function

_
R/W is a read /write signal which indicates a read when it is “H” and a
write when it is “L”.
___
BHE is a byte high enable signal which indicates that an odd address
is accessed when it is “L”.
Therefore, two bytes at even and odd addresses are accessed
___
simultaneously if address A0 is “L” and BHE is “L”.
ALE is an address latch enable signal used to latch the address signal
from a multiplexed signal of address and data. The latch is transparent
while ALE is “H” to let the address signal pass through and held
while ALE is “L”.

_
as address output
pins while E is “H” and as data I/O pin of even
_
addresses while E is “L” when the BYTE pin level is “L”. However,
if
_
an internal memory is read, external data is ignored while E is “L”.
When the BYTE pin level is “H” or 2•VCC , port P2 functions as an
_
address output pin_while E is “H” and as data I/O pin of even and odd
addresses while E is “L”. However,
if an internal memory is read,
_
external data is ignored while E is “L”.
Port P4 and its data direction which are located at address 0A16 and
0C16 are treated differently in evaluation chip mode. When these
addresses are accessed, the data bus width is treated as 16 bits
regardless of the BYTE pin level, and the access cycle is treated as
internal memory regardless of the wait bit.
____
___
The functions of HOLD and RDY are the same as those in
microprocessor mode. Clock
1 from P42/
1 pin is always output
regardless of signal output disable selection bit.
Ports P43 to P4 6 become MX, QCL, VDA, and VPA output pins
___
respectively. Port P47 becomes the DBC input pin.
The MX signal normally contents of flag m, but the contents of flag x
is output if the CPU is using flag x.
QCL is the queue buffer clear signal. It becomes “H” when the
instruction queue buffer is cleared, for example, when a jump
instruction is executed.
VDA is the valid data address signal. It becomes “H” while the CPU
is reading data from data buffer or writing data to data buffer. It also
becomes “H” when the first byte of the instruction (operation code) is
read from the instruction queue buffer.
VPA is the valid program address signal. It becomes “H” while the
CPU is reading an instruction code from the instruction queue buffer.

RESET CIRCUIT
_____
The microcomputer is released from the reset state when the RESET
pin is returned to “H” level after holding it at “L” level with the power
source voltage at 2.7 – 5.5 V. Program execution starts at the address
formed by setting address A23 – A16 to 0016, A15 – A8 to the contents
of address FFFF16 , and A7 – A0 to the contents of address FFFE16.
Figure 12 shows the status of the internal registers during reset.
Figure 13 shows an example of a reset circuit. If the stabilized clock
is input from the external to the main-clock oscillation circuit, the reset
input voltage must be 0.55 V or less when the power source voltage
reaches 2.7 V. If a resonator/oscillator is connected to the main-clock
oscillation circuit, change the reset input voltage from “L” to “H” after
the main-clock oscillation is fully stabilized.
