Table 15-5 Examples of Bit Rate B (bit/s) for Various BRR Settings (When n = 0)
Note: Bit rates are rounded to the nearest whole number.
The method of calculating the value to be set in the bit rate register (BRR) from the operating frequency and bit rate, on
the other hand, is shown below. N is an integer, 0 N 255, and the smaller error is specified.
N =
