Description

PCn (W) This bit controls the output level when the corresponding PCnOE bit is set.

When PCn=1, PCn pin outputs high level.

When PCn=0, PCn pin outputs low level.

PCn (R) When PCnOE=1 (i.e. output port), this bit is same as PCn (W).

When PCnOE=0, this bit indicates the input level. “1” means high and “0” means low.

I/O Port D

I/O Port D is shared with some special functions. When the special function is disabled, it is an general

I/O port and is same as Port A2. If it is configured as an output, it can source/sink 6mA. If it is configured

as an input, it has an internal pull-up resistor.
