UART0 Register Description

There are several control registers associated with the UART0 function. The S0CON register

controls the overall function of the UART0, while the SBRCON, SPPRE, S0RELL and S0RELH

registers control the Baud rate. The actual data to be transmitted and received on the serial

interface is managed through the S0BUF data register. The SMOD bit in the PCON register is used

to double the baud rate clock.
