Remarks 1. The maximum and minimum allowable values are applied to the baud rates for UART reception. Set the
parameters so that the baud rates for UART transmission should also fall within the allowable range.
2. The receive data length is 8 bits + a parity bit.
3. The numbers in the table are for sixteen samples per bit (i.e. when NSPB[3:0] = 0000b or 1111b).
