14.3.10 Bit Rate Register (SCBRR)
The bit rate register (SCBRR) is an eight-bit register that, together with the baud rate generator
clock source selected by the CKS1 and CKS0 bits in SCSMR, determines the serial
transmit/receive bit rate.
The CPU can always read and write the SCBRR. The SCBRR is initialized to H'FF by a reset or 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:

Find the bit rate error for the asynchronous mode by the following formula:
