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.

Table 15.3 shows sample N settings in BRR in normal asynchronous mode. Table 15.4 shows the
maximum bit rate for each frequency in normal asynchronous mode. Table 15.6 shows sample N
settings in BRR in clocked synchronous mode. Table 15.8 shows sample N settings in BRR in
Smart Card interface mode. In Smart Card interface mode, S (the number of basic clock periods in
a 1-bit transfer interval) can be selected. For details, refer to section 15.7.4, Receive Data
Sampling Timing and Reception Margin. Tables 15.5 and 15.7 show the maximum bit rates with
external clock input.
