Port 8
2
This pin is multiplexed with the SIO SRxD signal and the UART2 CTS signal. When bit 5 of the
UART2 control register (U2CON) is a “1”, the port acts as the CTS input signal. When the pin is
not being used as the UART2 CTS input and bit 2 of the SIO control register 2 (SIOCON2) is a
“1”, the port acts as the SIO SRxD input signal.

Port 8
3
This pin is multiplexed with the SIO STxD signal and the UART2 RTS signal. When bit 6 of the
UART2 control register (U2CON) is a “1”, the port acts as the RTS output signal. When the pin is
not being used as the UART2 RTS output and bit 3 of the SIO control register 1 (SIOCON1) is a
“1”, the port acts as the SIO STxD output signal.
