4.3.3.1 Set1.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.
Set & Register
Advanced Mode
DIS_BACK=
Legacy Mode
DIS_BACK=0
Set 0.Reg 4
Bit 7~5
-
Set 2.Reg 2
Bit 0, 5, 7
Bit 5, 7
Set 4.Reg 3
Bit 2, 3

Note that DIS_BACK=1 (Disable Backward operation) in legacy UART/SIR/ASK-IR mode will not
affect any register which that can operate legacy SIR/ASK-IR.
4.3.3.2 Set1.Reg 2~7
This registers is defined as same as Set 0 registers.
