3-bit I/O port. 1-bit or 3-bit read/write and test are
possible. Pull-up resistors are assignable to input pins by
software and are automatically disabled for output pins.
Pins are individually configurable as input or output.
2-bit input port. 1-bit or 2-bit read and test are possible.
Pull-up resistors are assignable by software.
4-bit input port. 1-bit or 4-bit read and test are possible.
Same as port 0
4-bit I/O ports. 1-, 4-, or 8-bit read/write and test are
possible. Pins are individually configurable as input or
output. 4-bit pull-up resistors are assignable to input pins
by software and are automatically disabled for output
pins. The N-channel open-drain or push-pull output can
be selected by software (1-bit unit)
4-bit I/O port.
1-bit or 4-bit read/write and test are possible.
Pull-up resistors are assignable to input pins by software
and are automatically disabled for output pins. Pins are
individually configurable as input or output.
