Function
This is a 4-bit input port (PORT0).
P01 to P03 are 3-bit pins for which an internal
pull-up resistor can be connected by software.
This is a 1-bit input port (PORT1).
These are 1-bit pins for which an internal pull-up
resistor can be connected by software.
P10/INT0 can select noise elimination circuit.
This is a 4-bit I/O port (PORT2).
These are 4-bit pins for which an internal pull-up
resistor can be connected by software.

Input and output in single-bit units can be specified.
When set for 4-bit units, an internal pull-up resistor
can be connected by software.
Input
E-B
This is an N-ch open-drain 4-bit I/O port (PORT5).
When set to open-drain, voltage is 13 V.
Also functions as data I/O pin (upper 4 bits)
for program memory (PROM) write/verify.

This is a programmable 4-bit I/O port (PORT6).
×
Input and output in single-bit units can be specified.
When set for 4-bit units, an internal pull-up resistor
can be connected by software.
Also functions as data I/O pin (lower 4 bits) for
program memory (PROM) write/verify.
This is a 4-bit I/O port (PORT8).
When set for 4-bit units, an internal pull-up resistor
can be connected by software.

Notes 1. Circuit types enclosed in brackets indicate Schmitt trigger circuits.
2. Low level input current leakage increases when input instructions or bit manipulation instructions are
executed.
