Write to the U0BRG register using the MOV instruction while transmission and reception are stopped.
Set bits CLK0 and CLK1 in the U0C0 register before writing to this register.
Do not write to the U0BRG register successively.
If the transfer data is 9 bits long, write to the higher byte (b15 to b8) first and then the lower byte (b7 to b0) in
8-bit units.
Write to the U0TB register using the MOV instruction. Word access is prohibited.
