Circuit
type
Function
J
General-purpose I/O port
The input is a hysteresis input type and with a built-in
noise canceller. When overcurrent is detected, the 12-
bit MPG output can be inactivated by the external edge
input.
J
General-purpose I/O port
The input is a hysteresis input type and with a built-in
noise canceller. Also serves as a 12-bit MPG output.
J
General-purpose I/O port
The input is a hysteresis input type and with a built-in
noise canceller. Also serves as the external clock input
for the 8/16-bit timer/counter.
J
General-purpose I/O port
The input is a hysteresis input type and with a built-in
noise canceller. Also serves as the serial data input for
the 8-bit serial interface.
J
General-purpose I/O port
The input is a hysteresis input type and with a built-in
noise canceller. Also serves as the serial data output
for the 8-bit serial interface.
J
General-purpose I/O port
The input is a hysteresis input type and with a built-in
noise canceller. Also serves as the serial transfer clock
for the 8-bit serial interface.
F
General-purpose I/O port
The output is an N-ch open-drain type. The input is a
hysteresis input type and with a built-in noise canceller.
Also serves as an external interrupt. The interrupt
input is also a hysteresis input type and with a built-in
noise canceller.
J
General-purpose I/O port
The input is a hysteresis input type and with a built-in
noise canceller. Also serve as an external interrupt or
as an MPG trigger input. The interrupt input is also a
hysteresis input type and with a built-in noise canceller.
I
Buzzer output-only pin
P-ch high-voltage open-drain output port
H
Low-current P-ch high-voltage open-drain output ports
Products with and without a built-in pull-down resistor
between these pins and the VFDP pin are provided.
