37
P31/TEMPO
G
This pin can be used for the bit 1 of Port 3 or the
output from PWM4.
The function of this pin can be switched by setting
the internal register of PWM4. This output has a high
drive-current capability.

P32/PWM1P,
P33/PWM1M
G
These pins are the pair of high-current driver outputs
for one of two motor coils.
They can be also used for the bits 2 and 3 of Port 3
by setting the internal register of the stepper motor
controller.

P34/PWM2P,
P35/PWM2M
G
These pins are the pair of high-current driver outputs
for one of two motor coils.
They can be also used for the bits 4 and 5 of Port 3
by setting the internal register of the stepper motor
controller.
44
P36/TEMPI
M
This analog input is connected to channel 1 of the
A/D converter.
It can also be used for the bit 6 of Port 3 when this
A/D input enable register bit is set to ‘0’.
45
P37/FUELI
M
This analog input is connected to channel 0 of the
A/D converter.
It can also be used for the bit 7 of Port 3 when this
A/D input enable register bit is set to ‘0’.
46
P40/PW
L
This pin has two functions.
When this pin is used as an open-drain output of
Port 4, the external voltage monitor reset should be
in the power down mode.
When it is used as the PW input of external voltage
monitor reset, the corresponding bit of the port data
register should be set to ‘1’.

P41/COM0 to
P44/COM3
K
These pins are the LCD common signal outputs.
When LCD is not used, these pins can be also used
for Port 4.
47
VINT
—
An external capacitor should be connected to this
pin for stabilizing the internal 3.0 V power supply.
For MB89PV940 and MB89P945, this pin should be
left open.
