Notes: This does not mean that the communication at the above baud rates is guaranteed. Careful consideration and
inspection under your environment are required before use.
Select clock divider count source in SELCLK bit of SIOn special mode register (SnSMOD).
Select divide-by value of clock divider in the CDIV bit of SIOn transmit control register (SnTCNT).
Set BRG set value in the SIOn baud rate register (SnBAUR).
