16.3.8
BRR is an 8-bit register that adjusts the bit rate. The initial value of BRR is H'FF. Table 16.3
shows the relationship between the N setting in BRR and the n setting in bits CKS1 and CKS0 of
SMR in asynchronous mode. Table 16.4 shows the maximum bit rate for each frequency in
asynchronous mode. The values shown in both tables 16.3 and 16.4 are values in active (high-
speed) mode. Table 16.5 shows the relationship between the N setting in BRR and the n setting in
bits CKS1 and CKS0 of SMR in clocked synchronous mode. The values shown in table 16.5 are
values in active (high-speed) mode. The N setting in BRR and error for other operating
frequencies and bit rates can be obtained by the following formulas:
[Asynchronous Mode]
[Clocked Synchronous Mode]
Legend B: Bit rate (bit/s)
N: BRR setting for baud rate generator (0 N 255)
n: CSK1 and CSK0 settings in SMR (0 n 3)
