Circuit

type

Function

A Main clock crystal oscillator pins

C Operating mode selection pin

Connect directly to VSS in normal operation. This pin

functions as the VPP pin in EPROM products.

D Reset I/O pin

This pin is an N-ch open-drain output type with a pull-up

resistor, and a hysteresis input type.

“L” is output from this pin by an internal reset source

when the option is set. The internal circuit is initialized

by the input of “L”.

This pin is with a noise canceller.

G General-purpose I/O ports

The input is a hysteresis input type and with a built-in

noise canceller. Although these ports also serve as an

analog input, analog input does not pass through the

hysteresis input noise canceller.

J

General-purpose I/O port

The input is a hysteresis input type and with a built-in

noise canceller. Also serves as an A/D converter

external activation.

J

General-purpose I/O ports

The input is a hysteresis input type and with a built-in

noise canceller.

G General-purpose I/O ports

The input is a hysteresis input type and with a built-in

noise canceller. Although these ports also serves as an

analog input, analog input does not pass through the

hysteresis input noise canceller.

B/K General-purpose I/O ports with a built-in noise

canceller

(single-clock operation)

Function as subclock crystal oscillator pins. (dual-clock

operation)

E General-purpose output port

E General-purpose output port

Also serves as a watchdog output.

E General-purpose output port

Also serves as the PWM output for the 8-bit PWM timer.

E General-purpose output port
