PACON0 and PACON1 are special function registers (SFRs) to select input/output state of the Port A pin. The
input/output state is different between input mode and output mode. Input or output is selected by using the PADIR
register.

PACON0
PACON1
The PA5C1 to PA0C1 pins and the PA5C0 to PA0C0 pins are used to select high-impedance output, P-channel open
drain output, N-channel open drain output, or CMOS output in output mode and to select high-impedance input,
input with a pull-down resistor, or input with a pull-up resistor in input mode.
