Section 16 Serial Communication Interface with FIFO (SCIF)
16.3.8
The bit rate register 2 (SCBRR2) is an eight-bit register that, together with the baud rate generator
clock source selected by the CKS1 and CKS0 bits in the SCSMR2, determines the serial
transmit/receive bit rate.
The CPU can always read and write the SCBRR2. The SCBRR2 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 SCBRR2 setting is calculated as follows:
