5.1.9 Bank1.Reg0~1 - Baud Rate Divisor Latch (BLL/BHL)
The two registers of BLL and BHL are baud rate divisor latch in the legacy UART/SIR/ASK-IR mode.
Read/Write these registers, if set in Advanced UART mode, will occur backward operation, that is, will
go to legacy UART mode and clear some register values shown table as follows.
