Table 12.2 Relationships between N Setting in BRR and Effective Bit Rate B
Notes: B
Table 12.3 shows sample N settings in BRR in normal asynchronous mode. Table 12.4 shows the
maximum bit rate for each frequency in normal asynchronous mode. Table 12.6 shows sample N
settings in BRR in clocked synchronous mode. For details, refer to section 12.4.2, Receive Data
Sampling Timing and Reception Margin in Asynchronous Mode. Tables 12.5 and 12.7 show the
maximum bit rates with external clock input.
