UART Baud Rate Generator
Baud Rate Generator Interrupts
If the baud rate generator (BRG) interrupt enable is set, the UART Receiver interrupt
asserts when the UART Baud Rate Generator reloads. This condition allows the Baud
Rate Generator to function as an additional counter if the UART functionality is not
employed.
The UART Baud Rate Generator creates a lower frequency baud rate clock for data
transmission. The input to the Baud Rate Generator is the system clock. The UART Baud
Rate High and Low Byte registers combine to create a 16-bit baud rate divisor value
