I/O

3-bit I/O port. 1-bit or 3-bit read/write and test is

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.

I/O

4-bit I/O ports. 1-, 4-, or 8-bit read/write and test is

possible. Pins are individually configurable as input

or output. 4-bit pull-up resistors are software

assignable to input pins and are automatically

disabled for output pins. The N-channel open-drain or

push-pull output can be selected by software (1-bit

unit)
