11.3.8
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 11.2 shows
the relationships between the N setting in BRR and bit rate B for asynchronous mode. The initial
value of BRR is H'FF, and it can be read or written to by the CPU at all times.
Table 11.2 Relationships between N Setting in BRR and Bit Rate B
Note: B: Bit rate (bit/s)
Table 11.3 shows sample N settings in BRR in asynchronous mode. Table 11.4 shows the
maximum bit rate for each frequency in asynchronous mode.
