16.2.4 Port 3 Control Registers 0, 1 (P3CON0, P3CON1)
Address: 0F21AH
Access: R/W
Access size: 8/16 bit
Initial value: 00H
Address: 0F21BH
Access: R/W
Access size: 8-bit
Initial value: 00H
P3CON0 and P3CON1 are special function registers (SFRs) to select input/output state of the Port 3 pin. The
input/output state is different between input mode and output mode. Input or output is selected by using the P3DIR
register.

P35C1 to P30C1, P35C0 to P30C0 (bits 5 to 0)
P35C1 to P30C1 and P35C0 to P30C0 are the bit 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.
