UART CONTROL REGISTER (UARTCON)

The control register for the UART is called UARTCON at address F6H. It has the following control functions:

Operating mode and baud rate selection

Multiprocessor communication and interrupt control

Serial receive enable/disable control

9th data bit location for transmit and receive operations (mode 2)

Parity generation and check for transmit and receive operations (mode 2)

UART transmit and receive interrupt control

A reset clears the UARTCON value to "00H". So, if you want to use UART module, you must write appropriate value to UARTCON.
