Chapter 10 Ports (INPUT, OUTPUT, I/O PORT)
(2) Port control registers (P4CON0, P4CON1, P5CON0, P5CON1, P6CON0, P6CON1,
P7CON0, P7CON1)
The port 4 control registers 0/1 (P4CON0, P4CON1), port 5 control registers 0/1 (P5CON0,
P5CON1), port 6 control registers 0/1 (P6CON0, P6CON1) and port 7 control registers
(P7CON0, P7CON1) are 4-bit special function registers (SFRs) used to select port output
mode.
The output mode may be CMOS output, N-channel open drain output, P-channel open drain
output or high-impedance output.
At system reset the port control registers are set to "0", and all ports are initialized to the CMOS
output mode.
