SCBRR is an 8-bit readable/writable register that sets the serial transfer bit rate in accordance with
the baud rate generator operating clock selected by bits CKS1 and CKS0 in SCSMR.
The SCBRR setting is found from the following equation.
Asynchronous Mode:
1. When sampling rate is 1/16
2. When sampling rate is 1/5
3. When sampling rate is 1/11
4. When sampling rate is 1/13
5. When sampling rate is 1/27
