Function
A Main clock crystal oscillator pins
I These pins can select either general-purpose CMOS
inputs or subclock oscillator pins by the mask options.
When these pins are used as a general-purpose input
pin, the pin is a hysteresis input with a built-in noise
canceller.
C Reset I/O pin
This pin is an N-ch open-drain output type with pull-up
resistor and a hysteresis input type. “L” is output from
this pin by an internal source. The internal circuit is
initialized by the input of “L”. This pin is with a noise
canceller.
D General-purpose CMOS I/O port
This port input is a hysteresis input, with a built-in
noise canceller.
D General-purpose CMOS I/O port
This port input is a hysteresis input, with a built-in
noise canceller. Also serves as a buzzer output.
D General-purpose CMOS I/O port
This port input is a hysteresis input, with a built-in
noise canceller. Also serves as the external activation
pin for the A/D converter.
D General-purpose CMOS I/O port
This port input is a hysteresis input, with a built-in
noise canceller. Also serves as the external clock input
for the 16-bit timer/counter.
D General-purpose CMOS I/O port
This port input is a hysteresis input, with a built-in
noise canceller. Also serves as the PWM output for
the 8-bit PWM timer.
D General-purpose CMOS I/O ports
These port inputs are a hysteresis input, with a built-in
noise canceller. Also serve as serial data outputs for
the 8-bit serial interface.
D General-purpose CMOS I/O port
This port input is a hysteresis input, with a built-in
noise canceller. Also serves as the serial transfer
clock output for the 8-bit serial interface.
G P-ch high-voltage open-drain output ports for large
current
