Table 7. SCIx_Compute_Baudrate
Note:
– This function takes a large ROM area as calculations for TR, RR and PR are done inside the
– If the selected baudrate speed is not possible, the closest possible value will be used.
– If there is no common prescalar factor for receiver and transmitter baudrates, then you will
– In half Duplex mode you can pass the same transmitter and receiver baudrates to get the
