Programmable 4-bit I/O port (PORT6).
I/O can be specified bit by bit. Pull-up
resistors can be provided by software in
units of 4 bits.
4-bit I/O port (PORT7).
Pull-up resistors can be provided by
software in units of 4 bits.
4-bit I/O port (PORT8).
Pull-up resistors can be provided by
software in units of 4 bits.
4-bit I/O port (PORT9).
Pull-down resistors can be provided by
software in units of 4 bits.
N-ch open-drain 4-bit I/O port (PORT10).
A pull-up resistor can be provided bit by bit
(mask option).
