Answer The UART function contains an internal baud-rate generator. This is controlled using the BRG register and the second bit, BRGH, in the UCR2 register. When BRGH is 0, the baud rate is equal to Fsys/{64*（N+1）} and when BRGH is equal to 1, the baud rate is equal to Fsys/{16*（N+1）}. N has a value between 0 and 255.
