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.

Note 1: Only use in high speed mode, when Bank0.Reg6.Bit7 is set.
** The percentage error for all baud rates, except where indicated otherwise, is 0.16%
