Chapter 17 Port 4
17.2.4 Port 4 Control Registers 0, 1 (P4CON0, P4CON1)
Address: 0F222H
Access: R/W
Access size: 8/16 bit
Initial value: 00H
Address: 0F223H
Access: R/W
Access size: 8-bit
Initial value: 00H
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.

P47C1 to P40C1, P47C0 to P40C0 (bits 7 to 0)
P47C1 to P40C1 and P47C0 to P40C0 are the bits for selecting the high-impedance output, P-channel open
drain output, N-channel open drain output, or CMOS output in output mode and for selecting the
high-impedance input, input with a pull-down resistor, or input with a pull-up resistor in input mode.
