Function

General-purpose CMOS I/O ports.

E This pin also serves as the buzzer output pin or the 12-bit

programmable pulse generator output.

General-purpose CMOS I/O ports.

E This pin also serves as the 8-bit PWM output pin. The pin is a

hysteresis input.

General-purpose CMOS I/O ports. These pins can also be

F used as N-channel open-drain ports.

The pins also serve as A/D converter analog input pins.

 Power supply pin

 Power (GND) pin



Power supply pin for the A-D converter.

Apply equal potential to this pin and the VSS pin.

MB89P935B:

Capacitance pin for regulating the power supply.



Connect an external ceramic capacitor of about 0.1 µF.

MB89935A/B:

This pin is not internally connedted. It is unnecessary to

connect a capacitor.



Internally connected pins

Be sure to leave them open.
