The following equation calculates the bit rate register (BRR) setting from the system clock
frequency and bit rate. N is an integer from 0 to 255, specifying the value with the smaller error.
Table 14.6 BRR Settings for Typical Bit Rate (bits/s) (when n = 0)
Table 14.7 Maximum Bit Rates for Various Frequencies (Smart Card Interface)
The bit rate error is calculated from the following equation.
