P4CON0 and P4CON1 are special function registers (SFRs) to select input/output state of the Port 4 pin. The
input/output state is different between input mode and output mode. Input or output is selected by using the P4DIR
register.

Initial value
Initial value
The P47C1 to P40C1 pins and the P47C0 to P40C0 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.
