15.3.9
BRR is an 8-bit register that adjusts the bit rate. As the SCI performs baud rate generator control
independently for each channel, different bit rates can be set for each channel. Table 15.2 shows
the relationships between the N setting in BRR and bit rate B for normal asynchronous mode,
clocked synchronous mode, and Smart Card interface mode. The initial value of BRR is H'FF, and
it can be read or written to by the CPU at all times.
