The M37210M3-XXXSP/FP is a single-chip microcomputer designed
with CMOS silicon gate technology. It is housed in a 52-pin shrink
plastic molded DIP or a 64-pin plastic molded QFP. This single-chip
microcomputer is useful for the channel selection system for TVs
because it provides PWM function, OSD display function and so on.
In addition to their simple instruction sets, the ROM, RAM, and I/O
addresses are placed on the same memory map to enable easy programming.
The features of the M37210E4-XXXSP/FP and the M37210E4SP/FP
are similar to those of the M37210M4-XXXSP except that these
chips have a built-in PROM which can be written electrically.
The differences between the M37210M3-XXXSP/FP, the M37210
M4-XXXSP, and the M37211M2-XXXSP are the ROM size, the RAM

This is connected to VSS .
To enter the reset state, the reset input pin must be kept at a “L” for 2µs or more (under normal VCC conditions).
If more time is needed for the crystal oscillator to stabilize, this “L” condition should be maintained for the required time.
This chip has an internal clock generating circuit. To control generating frequency, an external ceramic resonator or a quartz-crystal oscillator is connected between the XIN and
XOUT pins. If an external clock is used, the clock source should be connected the XIN pin and
the XOUT pin should be left open.
This is the timing output pin.
Port P0 is an 8-bit I/O port with directional registers allowing each I/O bit to be individually
programmed as input or output. At reset, this port is set to input mode. The output structure
is CMOS output.
The output structure is N-channel open-drain output. When PWM4, PWM5, PWM6 and
PWM7 are used, P00, P0 1, P02 and P03 are in common with PWM output pins of PWM4,
PWM5, PWM6 and PWM7.
Ports P10, P11 , P12, P13 and P14 are 5-bit I/O ports and have basically the same functions
as port P0. The output structure is CMOS output.
Ports P15, P16 and P17 are 3-bit input ports and they are in common with input pins of A-D
comparator (A-D1, A-D2 and A-D3).
Port P2 is an 8-bit I/O port and has basically the same functions as port P0.
The output structure is CMOS output.
Ports P30 and P3 1 are 2-bit I/O ports and have basically the same functions as port P0.
The output structure is CMOS output.
Ports P3 2, P33, P34 and P35 are 4-bit input ports and ports P32 and P33 are in common
with external clock input pins of timers 2 and 3. Ports P3 4 and P3 5 are in common with
external interrupt input pins INT1 and INT2. Port P35 is in common with an input pin of A-D
comparator (A-D4).
Ports P40 and P4 1 are 2-bit I/O ports and have basically the same functions as port P0.
When serial I/O is used, ports P40 and P41 are in common with SOUT pin and SCLK pin, respectively.
Port P42 is an 1-bit Input port, and it is common with an input pin of A-D comparator (A-D5)
and serial input pin (SIN).
Port P6 is an 4-bit output port. The output structure is N-channel open-drain. This port is in
common with 6-bit PWM output pins PWM0-PWM3.
This is the I/O pins of the clock generating circuit for the CRT display function.
This is the horizontal synchronizing signal input for CRT display.
This is the vertical synchronizing signal input for CRT display.
This is a 4-bit output pin for CRT display. The output structure is CMOS output. This is in
common with port P52 – P55.
This is an output pin for 14-bit PWM.

INTERRUPTS
Interrupts can be caused by 12 different sources consisting of 3 external, 7 internal, 1 software, and reset.
Interrupts are vectored interrupts with priorities shown in Table 1. Reset is also included in the table because its operation is similar to an
interrupt.
When an interrupt is accepted, the registers are pushed, interrupt
disable flag I is set, and the program jumps to the address specified
in the vector table. The interrupt request bit is cleared automatically.
The reset can never be disabled. Other interrupts are disabled when
the interrupt disable flag is set.
All interrupts except the BRK instruction interrupt have an interrupt
request bit and an interrupt enable bit. The interrupt request bits are
in interrupt request registers 1 and 2 and the interrupt enable bits are
in interrupt control registers 1 and 2. Figure 4 shows the structure of
the interrupt request registers 1 and 2 and interrupt control registers
1 and 2.
Interrupts other than the BRK instruction interrupt and reset are accepted when the interrupt enable bit is “1”, interrupt request bit is “1”,
and the interrupt disable flag is “0”. The interrupt request bit can be
reset with a program, but not set. The interrupt enable bit can be set
and reset with a program.
Reset is treated as a non-maskable interrupt with the highest priority.

TIMERS
The M37210M3-XXXSP has 4 timers: timer 1, timer 2, timer 3 and
timer 4. All timers are 8-bit timers with the 8-bit timer latch. The timer
block diagram is shown in Figure 7.
All of the timers count down and their divide ratio is 1/(n+1), where n
is the value of timer latch. The value is set to a timer at the same time
by writing a count value to the corresponding timer latch (addresses
00F016 to 00F316 : timers 1 to 4).
The count value is decremented by 1. The timer interrupt request bit
is set to “1” by an timer overflow at the next count pulse after the
count value reaches “0016.”
set bit 0 of the timer 34 mode register (address 00F516 ) to “0” before
the execution of the STP instruction (f(XIN)16 is selected as the timer
3 count source). The internal STP state is released by timer 4 overflow at these state, the internal clock is connected .
Because of this, the program starts with stable clock.
The structure of timer-related registers is shown in Figure 6.

Timer 3 can select one of the following count sources:
f(XIN)/16
External clock from the P33/TIM3 pin and the HSYNC pin
The count source of timer 3 is selected by setting bits 5 and 0 of the
timer 34 mode register (address 00F516).
Timer 3 interrupt request occurs at timer 3 overflow.
•

At reset, timers 3 and 4 are connected by hardware and “FF 16” is
automatically set in timer 3; “0716” in timer 4. The f(X IN)/16 is selected as the timer 3 count source. The internal reset is released by
timer 4 overflow at these state, the internal clock is connected .
At execution of the STP instruction, timers 3 and 4 are connected by
hardware and “FF16” is automatically set in timer 3; “0716” in timer 4.
However, the f(XIN)16 is not selected as the timer 3 count source. So

SERIAL I/O
M37210M3-XXXSP has a serial I/O.
A block diagram of the serial I/O is shown in Figure 8.
Synchronous input/output clock (SCLK), and the serial I/O pins (SOUT,
SIN) are used as port P4. The serial I/O mode registers (address
00DC16) are 8-bit registers. Bits 0, 1 and 2 of these registers are
used to select a synchronous clock source.
Bit 3 decides whether parts of P4 will be used as a serial I/O or not.
To use P42 as a serial input, set the directional register bit which corresponds to P42 to “0”. For more information on the directional register, refer to the I/O pin section.
The serial I/O function is discussed below. The function of the serial
I/O differs depending on the clock source ; external clock or internal
clock.

The serial I/O counter is set to 7 when data is stored in the serial I/O
register. At each falling edge of the transfer clock, serial data is output to SOUT. During the rising edge of this clock, data can be input
from SIN and the data in the serial I/O register will be shifted 1 bit.
Transfer direction can be selected by bit 5 of serial I/O mode register.
After the transfer clock has counted 8 times, the serial I/O register will
be empty and the transfer clock will remain at a high level. At this time
the interrupt request bit will be set.
External clock- If an external clock is used, the interrupt request will
be sent after the transfer clock has counted 8 times but transfer clock
will not stop.
Due to this reason, the external clock must be controlled from the
outside. The external clock should not exceed 1MHz at a duty cycle
of 50%. The timing diagram is shown in Figure 9. When using an external clock for transfer, the external clock must be held at “H” level
when the serial I/O counter is initialized. When switching between the
internal clock and external clock, the switching must not be performed during transfer. Also, the serial I/O counter must be initialized
after switching.
Notes 1: On programming, note that the serial I/O counter is set by
writing to the serial I/O register with the bit managing instructions as SEB and CLB instructions.
2: When an external clock is used as the synchronizing clock,
write transmit data to the serial I/O register at “H” of the
transfer clock input level.

PWM OUTPUT CIRCUIT
(1) Introduction
The M37210M3-XXXSP/FP and M37210M4-XXXSP are
equipped with one 14-bit PWM (DA) and eight 6-bit PWMs
(PWM0-PWM7), and the M37211M2-XXXSP is equipped with
six 6-bit PWMs (PWM0-PWM5). The 14-bit resolution gives DA
the minimum resolution bit width of 500ns (for f(XIN) = 4MHz)
and a repeat period of 8192µs. PWM0-PWM7 have a 6-bit resolution with minimum resolution bit width of 16ms and repeat period of 1024µs.
Block diagram of the PWM is shown in Figure 16.
The PWM timing generator section applies individual control
signals to DA and PWM0-7 using clock input XIN divided by 2
as a reference signal.
(2) Data Setting
The output pins PWM0-3 are in common with port P6 and
PWM4-7 are in common with port P00-P03.
For PWM output, each PWM output selection bit (bit 1 to 7 of
PWM output control register 1, bit 0, 1 of PWM output control
register 2, should be set. When DA is used for output, first set
the higher 8-bit of the DA-H register (address 00CE16), then the
lower 6-bit of the DA-L register (address 00CF16).
When one of the PWM0-7 is used for output, set the 6-bit in the
PWM0-7 register (address 00D0 16 to 00D416, 00F616 to
00F816), respectively.
(3) Transferring Data from Registers to PWM
Circuit
The data written to the PWM registers. 8 bits of the DA-H register is transferred to 14-bit PWM circuit when writing to lower 6
bits of the DA-L register.
(4) Operation of the 6-bit PWMs
The timing diagram of the eight 6-bit PWMs (PWM0-7) is shown
in Figure 13. One period (T) is composed of 64 (26) segments.
There are six different pulse types configured from bits 0 to 5
representing the significance of each bit. These are output
16
within one period in the circuit internal section. Refer to Figure
13 (a).
Six different pulses can be output from the PWM.
These can be selected by bits 0 through 5. Depending on the
content of the 6-bit PWM latch, pulses from 5 to 0 are selected.
The PWM output is the difference of the sum of each of these
pulses. Several examples are shown in Figure 13 (b). Changes
in the contents of the PWM latch allows the selection of 64
lengths of high-level area outputs varying from 0/64 to 63/64. A
length of entirely high-level output cannot be output, i.e. 64/64.
(5) 14-bit PWM Operation
The output example of the 14-bit PWM is shown in Figure 14.
The 14-bit PWM divides the data within the PWM latch into the
lower 6 bits and higher 8 bits.
A high-level area within a length DH times τ is output every short
area of t = 256 τ =128µs as determined by data DH of the higher
8 bits.
Thus, the time for the high-level area is equal to the time set by
the lower 8 bits or that plus τ. As a result, the short-area period
t ( = 128µs, approx. 7.8 kHz) becomes an approximately repetitive period.
(6) Output after Reset
At reset the output of port P6 is in the high impedance state and
the contents of the PWM register and latch are undefined. Note
that after setting the PWM register, its data is transferred to the
latch.

A-D COMPARATOR
Block diagram of A-D comparator is shown in Figure 18. A-D comparator consists of 5-bit D-A converter and comparator. The A-D control register can generate 1/64 V CC-step internal analog voltage
based on the settings of bits 0 to 4.
Table 3 gives the relation between the descriptions of A-D control
register bits 0 to 4 and the generated internal analog voltage. The
comparison result of the analog input voltage and the internal analog
voltage is stored in the A-D control register, bit 5.
After selection of an analog input pin by bits 0-2 of A-D mode register
(address 00EE16), the digital value corresponding to the internal analog voltage to be compared is then written in the A-D control register,
bit 0 to 3 and an analog input pin is selected. After 16 machine cycle,
the voltage comparison is completed.

CRT DISPLAY FUNCTIONS
(1) Outline of CRT Display Functions
Table 4 outlines the CRT display functions of the M37210M3-XXXSP.
The M37210M3-XXXSP incorporates a 18 columns ✕ 2 lines CRT
display control circuit. CRT display is controlled by the CRT display
control register.
Up to 96 kinds of characters can be displayed, and colors can be
specified for each character. Four colors can be displayed on one
screen. A combination of up to 7 colors can be obtained by using
each output signal (R, G and B).
Characters are displayed in a 12 ✕ 16 dot configuration to obtain
smooth character patterns (refer to Figure 19).
The following shows the procedure how to display characters on the
CRT screen.

➀ Set the character to be displayed in display RAM.
➁ Set the display color by using the color register.
➂ Specify the color register in which the display color is set by using the display RAM.
➃ Specify the vertical position and character size by using the vertical position register and the character size register.
➄ Specify the horizontal position by using the horizontal position
register.
➅ Write the display enable bit to the designated block display flag of
the CRT control register. When this is done, the CRT starts operation according to the input of the VSYNC signal.
The CRT display circuit has an extended display mode.
This mode allows multiple lines (more than 3 lines) to be displayed
on the screen by interrupting the display each time one line is displayed and rewriting data in the block for which display is terminated
by software.
Figure 21 shows a block diagram of the CRT display control circuit.
Figure 20 shows the structure of the CRT display control register.

(2) Display Position
The display positions of characters are specified in units called a
“block”. There are two blocks, block 1 and block 2.
Up to 18 characters can be displayed in one block (refer to (4)
Memory for Display).
The display position of each block in both horizontal and vertical directions can be set by software.
The horizontal direction is common to all blocks, and is selected from
64-step display positions in units of 4Tc (Tc = oscillating cycle for display).
The display position in the vertical direction is selected from 128-step
display positions for each block in units of four scanning lines.
Block 2 is displayed after the display of block 1 perfectly (fig. 24(a)).
Then if the display of block 2 starts during the display of block 1, only
block 1 is displayed. As same, when multiline display, block 1 is displayed after the display of block 2 perfectly (fig. 24(b)).
The vertical position can be specified from 128-step positions (four
scanning lines per step) for each block by setting values 0016 to 7F16
to bits 0 to 6 in the vertical position register (addresses 00E116 and
00E215). Figure 22 shows the structure of the vertical position register.

The horizontal direction is common to all blocks, and can be specified from 64-step display positions (4Tc per step (Tc = oscillating
cycle for display) by setting values 0016 to 3F16 to bits 0 to 5 in the
horizontal position register (address 00E016 ). Figure 23 shows the

(3) Character Size
The size of characters to be displayed can be selected from three
sizes for each block. Use the character size register (address
00E416) to set a character size. The character size in block 1 can be
specified by using bits 0 and 1 in the character size register ; the
character size in block 2 can be specified by using bits 2 and 3. Figure 25 shows the structure of the character size register.
The character size can be selected from three sizes : small size, medium size and large size. Each character size is determined by the
number of scanning lines in the height (vertical) direction and the
cycle of display oscillation ( = Tc) in the width (horizontal) direction.
The small size consists of [one scanning line] ✕ [1 Tc] ; the medium
size consists of [two scanning lines] ✕ [2 Tc] ; and the large size consists of [three scanning lines] ✕ [3 Tc].
Table 5 shows the relationship between the set values in the character size register and the character sizes.

(4) Memory for Display
There are two types of memory for display : ROM of CRT display (addresses 300016 to 35FF16 , 380016 to 3DFF16) used to store character dot data (masked) and display RAM (addresses 200016 to
20B116) used to specify the colors of characters to be displayed. The
following describes each type of display memory.
➀ ROM for display (addresses 300016 to 35FF16 and 380016 to
3DFF16)
The CRT display ROM contains dot pattern data for characters to be
displayed. For characters stored in this ROM to be actually displayed, it is necessary to specify them by writing the character code
inherent to each character (code determined based on the addresses in the CRT display ROM) into the CRT display RAM.
The CRT display ROM has a capacity of 3K bytes. Because 32 bytes
are required for one character data, the ROM can contain up to 96
kinds of characters.
The CRT display ROM space is broadly divided into two areas. The
[vertical 16 dots] × [horizontal (left side) 8 dots] data of display characters are stored in addresses 300016 to 35FF 16 ; the [vertical 16
dots] × [horizontal (right side) 4 dots] data of display characters are
stored in addresses 380016 to 3DFF16 (refer to Figure 27). Note however that the four upper bits in the data to be written to addresses
380016 to 3DFF16 must be set to “1” (by writing data F016 to FF16).

The character code used to specify a character to be displayed is
determined based on the address in the CRT display ROM in which
that character is stored.
Assume that data for one character is stored at addresses 3XX016 to
3XXF16 (XX denotes 0016 to 5F16) and addresses 3YY016 to 3YYF16
(YY denotes 8016 to DF16), then the character code for it is “XX16”.

➁ RAM for display (address 200016 to 20B116 )
The CRT display RAM is allocated at addresses 200016 to 20B116 ,
and is divided into a display character code specifying part and display color specifying part for each block.
Table 7 shows the contents of the CRT display RAM.
When a character is to be displayed at the first character (leftmost)
position in block 1, for example, it is necessary to write the character
code to the seven low-order bits (bits 0 to 6) in address 200016 and
the color register No. to the two low-order bits (bits 0 and 1) in address 208016. The color register No. to be written here is one of the
four color registers in which the color to be displayed is set in advance. For details on color registers, refer to (5) Color Registers.
The structure of the CRT display RAM is shown in Figure 27.

(5) Color Registers
(6) Multiline Display
The color of a displayed character can be specified by setting the
color to one of the four color registers (CO0 to CO3 : addresses
00E616 to 00E9 16) and then specifying that color register with the
CRT display RAM.
There are three color outputs : R, G and B. By using a combination
of these outputs, it is possible to set 23 -1 (when no output) = 7 colors. However, because only four color registers are available, up to
four colors can be displayed at one time.
R, G and B outputs are set by using bits 1 to 3 in the color register.
Bit 5 is used to specify whether a character output or blank output.
Figure 29 shows the structure of the color register.
The M37210M3-XXXSP can normally display two lines on the CRT
screen by displaying two blocks at different vertical positions.
In addition, it allows up to 16 lines to be displayed by using a CRT
interrupt.
The CRT interrupt works in such a way that when display of one
block is terminated, an interrupt request is generated.
In other words, character display for a certain block is initiated when
the scanning line reaches the display position for that block (specified with vertical position register) and when the range of that block
is exceeded, an interrupt is applied.

Note : A CRT interrupt does occurs at the end of display regardless
of display on or off. In other words, even if a block is set to off
display with the display control bit of the CRT control register
(address 00EA16 ), a CRT interrupt request occurs (refer to
Figure 30).

(7) Character Border Function
An border of a one clock (one dot) equivalent size can be added to a
character to be displayed in both horizontal and vertical directions.
The border is output from the OUT pin. In this case, bit 5 in the color
register (contents output from the OUT pin) is nullified, and the border is output from the OUT pin instead.
Border can be specified in units of block by using the border select
register (address 00E516 ). Table 8 shows the relationship between
the values set in the border select register and the character border
function. Figure 32 shows the structure of the border select register.

(8) CRT Output Pin Control
CRT output pins R, G, B and OUT are respectively shared with port
P52, P53, P54 and P55. When the corresponding bits in the port P5
control register (address 00CB16) are cleared to “0”, the pins are set
for CRT output ; when the bits are set to “1”, the pins function as port
P5 (general- purpose output pins).
The polarities of CRT outputs (R, G, B and OUT, as well as HSYNC
and VSYNC) can be specified by using the CRT port control register
(address 00EC16).
Use bits 0 to 4 in the CRT port control register to set the output polarities of HSYNC , VSYNC , R/G/B and OUT. When these bits are
cleared to “0”, a positive polarity is selected ; when the bits are set to
“1”, a negative polarity is selected.
Bits 5 to 7 in the CRT port control register are used to specify pin by
pin whether normal video signals or R-MUTE, G-MUTE, and BMUTE signals are output from each pin (R, G, B). When set for RMUTE, G-MUTE, and B-MUTE outputs, the whole background
colors of the screen become red, green, and blue.
Figure 33 shows the structure of the CRT port control register.

INTERRUPT INTERVAL DETERMINATION
FUNCTION
The M37210M3-XXXSP incorporates an interrupt interval determination circuit. This interrupt interval determination circuit has an 8-bit
binary up counter as shown in Figure 34.
Using this counter, it determines an interval or a pulse width on the
INT1 or INT2 (refer to Figure 36).
The following describes how the interrupt interval is determined.
1. The interrupt input to be determined (INT1 input or INT2 input) is
selected by using bit 2 in the interrupt interval determination control register (address 00D816 ). When this bit is cleared to “0”, the
INT1 input is selected ; when the bit is set to “1”, the INT2 input is
selected.
2. When the INT1 input is to be determined, the polarity is selected
by using bit 3 of the interrupt interval determination control register ; when the INT2 input is to be determined, the polarity is selected by using bit 4 of the interrupt interval determination control
register.
When the relevant bit is cleared to “0”, determination is made of
the interval of a positive polarity (rising transition) ; when the bit is
set to “1”, determination is made of the interval of a negative po-
larity (falling transition).
3. The reference clock is selected by using bit 1 of the interrupt interval determination control register. When the bit is cleared to “0”, a
64ms clock is selected ; when the bit is set to “1”, a 32µs clock is
selected (based on an oscillation frequency of 4MHz in either
case).
4. Simultaneously when the input pulse of the specified polarity (rising or falling transition) occurs on the INT1 pin (or INT2 pin), the 8bit binary up counter starts counting up with the selected
reference clock (64µs or 32µs).
5. Simultaneously with the next input pulse, the value of the 8-bit binary up counter is loaded into the determination register (address
00D716) and the counter is immediately reset (0016 ). The reference clock is input in succession even after the counter is reset,
and the counter restarts counting up from “0016”.
6. When count value “FE16 ” is reached, the 8-bit binary up counter
stops counting. Then, simultaneously when the next reference
clock is input, the counter sets value “FF16 ” to the determination
register.

RESET CIRCUIT
The M37210M3-XXXSP is reset according to the sequence shown in
Figure 39. It starts the program from the address formed by using the
content of address FFFF1 6 as the high order address and the content of the address FFFE16 as the low order address, when the
RESET pin is held at “L” level for no less than 2µs while the power
voltage is 5V ± 10% and the crystal oscillator oscillation is stable and
then returned to “H” level. The internal initializations following reset
are shown in Figure 37.
An example of the reset circuit is shown in Figure 38. The reset input
voltage must be kept below 0.6V until the supply voltage surpasses
4.5V.

I/O PORTS
(1) Port P0
Port P0 is an 8-bit I/O port with N-channel open-drain output.
As shown in the memory map (Figure 3), port P0 can be accessed at zero page memory address 00C016.
Port P0 has a directional register (address 00C116) which can be
used to program each individual bit as input (“0”) or as output
(“1”). If the pins are programmed as output, the output data is
latched to the port register and then output. When data is read
from the output port the output pin level is not read, only the
latched data in the port register is read. This allows a previously
output value to be read correctly even though the output voltage
level is shifted up or down.
Pins set as input are in the floating state and the signal levels can
thus be read. When data is written into the input port, the data is
latched only to the port latch and the pin still remains in the floating state.
Ports P0 0-P03 are in common with 6-bit PWM outputs PWM4PWM7. For the M37211M2, ports P00 and P0 1 are in common
with 6-bit PWM outputs PWM4 and PWM5.
(2) Port P1
Port P1 has basically the same function as port P0 except the
output structure is CMOS output. But, pins P1 5-P1 7 are input
ports and in common with analog input pins A-D1-A-D3.
(3) Port P2
Port P2 has basically the same function as port P1.
(4) Port P3
Port P3 are a 2-bit I/O port and a 4-bit input port with function
similar to port P2, but the output structure of P30, P31 is CMOS
output.
P32, P33 are in common with the external clock input pins of timer
2 and 3.
P34, P3 5 are in common with the external interrupt input pins
INT1, INT2 and P35 with the analog input pin of A-D comparator
A-D4.
(5) Port P4
Port P4 are a 2-bit I/O port and a 1-bit input port with function
similar to port P2, but the output structure is N-channel opendrain output.
When a serial I/O function is selected, P40-P4 2 are in common
with pins SOUT, SCLK and SIN.
(6) OSC1, OSC2 pins
Clock input/output pins for CRT display function.
(7) HSYNC, VSYNC pins
HSYNC is a horizontal synchronizing signal input pin for CRT display.
VSYNC is a vertical synchronizing signal input pin for CRT display.
(8) R, G, B, OUT pins
This is an 4-bit output pin for CRT display and in common with
P52-P55.
(9) Port P6
Port P6 is an 4-bit output port with function similar to port P0, but
the output structure is N-channel opendrain output.
This port is in common with 6-bit PWM output pin PWM0-PWM3.
(10) D-A pin
This is a 14-bit PWM output pin.

CLOCK GENERATING CIRCUIT
The built-in clock generating circuit is shown in Figure 44.
When the STP instruction is executed, the internal clock φ stops oscillating at “H” level. At the same time, timers 3 and 4 are connected
in hardware and “FF16” is set in the timer 3, “0716 ” is set in the timer
4. Select f(XIN)/16 as the timer 3 count source (set bit 0 of the timer
34 mode register to “0” before the execution of the STP instruction).
And besides, set the timer 3 and timer 4 interrupt enable bits to disabled (“0”) before execution of the STP instruction.
The oscillator is restarted when an external interrupt is accepted.
However, the internal clock φ keeps its “H” level until timer 4 overflows.
This is because the oscillator needs a set-up period if a ceramic resonator or a quartz-crystal oscillator is used.
When the WIT instruction is executed, the internal clock φ stops in the
“H” level but the oscillator continues running. This wait state is
cleared when an interrupt is accepted (Note). Since the oscillation
does not stop, the next instructions are executed at once.
To return from the stop or the wait state, set the interrupt enable bit to
“1” before executing the STP or the WIT instruction.
Note : In the wait mode, the following interrupts are invalid.
(1) VSYNC interrupt
(2) CRT interrupt
(3) Timer 2 interrupt using P32/TIM2 pin input as count source
(4) Timer 3 interrupt using P33/TIM3 pin input as count source
(5) Timer 4 interrupt using f(XIN)/2 as count source
The circuit example using a ceramic resonator (or a quartz crystal
oscillator) is shown in Figure 42.
Use the circuit constants in accordance with the resonator
manufacture’s recommended values.
The example of external clock usage is shown in Figure 43 XIN is the
input, and XOUT is open.

PROGRAMMING NOTES
(1) The divide ratio of the timer is 1/ (n + 1).
(2) Even though the BBC and BBS instructions are executed immediately after the interrupt request bits are modified (by the program), those instructions are only valid for the contents before
the modification. At least one instruction cycle is needed (such as
an NOP) between the modification of the interrupt request bits
and the execution of the BBC and BBS instructions.
(3) After the ADC and SBC instructions are executed (indecimal operation mode), one instruction cycle (such as an NOP) is needed
before the SEC, CLC, or CLD instructions are executed.
(4) An NOP instruction is needed immediately after the execution of
a PLP instruction.
(5) In order to avoid noise and latch-up, connect a bypass capacitor
( ≈ 0.1µF) directly between the VCC pin and VSS pin using a thick
wire.
DATA REQUIRED FOR MASK ORDERS
The following are necessary when ordering a mask ROM production.
(1) Mask ROM Order Confirmation Form
(2) Mark Specification Form
(3) Data to be written to ROM, in EPROM form (28-pin DIP type
27256, three identical copies)
PROM Programming Method

❈ 1. Confirmation
Specify the name of the product being ordered and the type of EPROMs submitted.
Three EPROMs are required for each pattern.
If at least two of the three sets of EPROMs submitted contain identical data, we will produce masks based on
this data. We shall assume the responsibility for errors only if the mask ROM data on the products we produce
differs from this data. Thus, extreme care must be taken to verify the data in the submitted EPROMs.
