14.2.9
The bit rate register (SCBRR) is an 8-bit register that, together with the baud rate generator clock
source selected by the CKS1 and CKS0 bits in the serial mode register (SCSMR), determines the
serial transmit/receive bit rate.
The CPU can always read and write to SCBRR. SCBRR is initialized to H'FF by a reset, and in
module standby or standby mode. Each channel has independent baud rate generator control, so
different values can be set in two channels.
The SCBRR setting is calculated as follows:

Note: The bit rate error in asynchronous is given by the following formula:
