21.3 Description of Operation
21.3.1
For each pin of Port A, either output or input is selected by setting the Port A direction register (PADIR).
In output mode, high-impedance output mode, P-channel open drain output mode, N-channel open drain output mode,
or CMOS output mode can be selected by setting the Port A control registers 0 and 1 (PACON0 and PACON1).
In input mode, high-impedance input mode, input mode with a pull-down resistor, or input mode with a pull-up resistor
can be selected by setting the Port A control registers 0 and 1 (PACON0 and PACON1).
At system reset, high-impedance output mode is selected as the initial state.
In output mode, “L” or “H” level is output to each pin of Port A depending on the value set by the Port A data register
(PAD).
In input mode, the input level of each pin of Port A can be read from the Port A data register (PAD).
