I/O
4-bit I/O port.
1-bit and 4-bit read/write and test is possible.
4-bit unit pull-up resisters are assignable to input pins
by software and are automatically disabled for output
pins. Each bit pin can be allocated as input or output
(1-bit unit). The N-ch open drain or push-pull output
may be selected by software (1-bit unit).
