UART Baud Rate Generator
The UART Baud Rate Generator creates a lower frequency baud rate clock for data
transmission. The input to the BRG is the system clock. The UART Baud Rate High and
Low Byte Registers combine to create a 16-bit baud rate divisor value (BRG[15:0]) that
sets the data transmission rate (baud rate) of the UART. The UART data rate is calculated
using the following equation:
