Note 1: The value written to UARTxFBRD will be valid upon currently ongoing transmission or reception is complete.
Note 2: The value written to UARTxFBRD will be valid when data is written to UARTxLCR_H.
Note 3: Set <BAUDDIVFRAC[5:0]> before "1" is set to UARTxCR>UARTEN>.
Note 4: The minimum value of a baud-rate divisor is 1 and the maximum value is 65535. Therefore, the integer part of a
baud-rate divisor cannot be set to 0. The fractional part of a baud-rate divisor must be set 0 if the integer part of
a baud-rate divisor is 65535.
