Bit Rate Register (BRR)

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