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).
4-bit input port.
1-bit and 4-bit read and test is possible.
4-bit unit pull-up resistors are assignable to input pins
by software.
4-bit I/O port. 1-bit and 4-bit read/write and test is
possible. I/O function is same as port 0.
4-bit I/O port. 1-bit and 4-bit read/write and test is
possible. I/O function is same as port 0.
3-bit I/O port. I/O function is same as port 0 except
that port 4 is 3-bit I/O port.
4-bit I/O port. 1-, 4-bit and 8-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 (4-bit unit).
4-bit I/O port. 1-, 4-bit and 8-bit read/write and test is
possible. I/O function is same as port 6, 7.
