Port P84
This pin is multiplexed with the UART1 TxD signal.
When UART1 is in transmit mode, the pin acts as the
TxD output signal.
Port P85
This pin is multiplexed with the UART1 RxD signal.
When UART1 is in receive mode, the pin acts as the
RxD input signal.
Port P86
This pin is multiplexed with the UART1 CTS signal.
When bit 5 of the UART1 control register (U1CON) is
a “1”, the port acts as the CTS input signal.
Port P87
This pin is multiplexed with the UART1 RTS signal.
When bit 6 of the UART1 control register (U1CON) is
a “1”, the port acts as the RTS output signal.
