Baud Rate Divisor bits [15:8]. Most significant byte of baud
rate divisor. These bits are cleared to 0 on reset.
Reserved. Unknown During Read.
Baud Rate Divisor bits [7:0]. Least significant byte of baud
rate divisor. These bits are cleared to 0 on reset. The baud
rate divisor is calculated as follows:
Baud rate divisor BAUDDIV = (F
rate)) –1
where F
baud rate divisor of zero is not allowed and will result in no
data transfer.
