function
This is a 4-bit input port (PORT0).
Connection of an on-chip pull-up resistor can be
specified in 3-bit units by software for P01 to P03.
This is a 4-bit input port (PORT1).
Connection of an on-chip pull-up resistor can be
specified in 4-bit units by software.
P10/INT0 can select noise elimination circuit.
This is a 4-bit I/O port (PORT2).
Connection of an on-chip pull-up resistor can be
specified in 4-bit units by software.
This is a programmable 4-bit I/O port (PORT3).
Input and output can be specified in bit units.
Connection of an on-chip pull-up resistor can be
specified in 4-bit units by software.
This is an N-ch open-drain 4-bit I/O port (PORT4).
When set to open-drain, voltage is 13 V.
Also functions as data I/O pin (lower 4 bits)
for program memory (PROM) write/verify.
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.
