27.3.8
SCBRR is an 8-bit register that set the serial transmission/reception bit rate in accordance with the
baud rate generator operating clock selected by bits CKS1 and CKS0 in SCSMR.
SCBRR can always be read from and written to by the CPU.
The SCBRR setting is found from the following equation.
Asynchronous mode:
