UA0BRTL and UA0BRTH are special function registers (SFRs) to set the count value of the baud rate generator which
generates baud rate clocks.
For the relationship between the count value of the baud rate generator and baud rate, see Section 11.3.2, “Baud Rate”.
Note:
Always set the UA0BRTL and UA0BRTH registers while communication is stopped, and do not rewrite them during
communication.
