The setting of the nominal bit rate is based on the PCK5 which is 480M which you can change in the conf_clock.h. Below is the default configuration. The time quanta is 20MHz / (1+1) = 10MHz. And each bit is (1 + NTSEG1 + 1 + NTSEG2 + 1) = 20 time quanta which means the bit rate is 10MHz/20=500KHz.Nominal bit Baud Rate Prescaler
