IR_MSP - IR mode Select Pulse
Write to 1 causes the transmitter (IRTX) to send a 64 µs pulse to setup a special IR front-
end operational mode. When IR front-end module uses mode select pin (MD) and
transmitter IR pulse (IRTX) to switch high speed IR (such as FIR or MIR) or low speed IR
(SIR or ASK-IR), this bit should be used.
SIR_SL2~0 - SIR (Serial IR) mode select.
These bits are to program the operational mode of the SIR front-end module. These
values of SIR_SL2~0 will automatically load to pins of IR_SL2~0, respectively, when (1)
AM_FMT=1 (Automatic Format, in Set7.Reg7.Bit7), (2) the mode of Advanced UART is
set to SIR (AD_MD2~0, in Set0.Reg4.Bit7~0).
Reserved, write 0.
AIR_SL2~0 - ASK-IR mode Select.
These bits will setup the operational mode of ASK-IR front-end module when AM_FMT=1
and AD_MD2~0 are set to ASK-IR mode. These values will automatically load to
IR_SL2~0, respectively.

FIR_SL2~0 - FIR mode select.
These bits setup the operational mode of FIR front-end module when AM_FMT=1 and
AD_MD2~0 set to FIR mode. These values will automatically load to IR_SL2~0,
respectively.
Reserved, write 0.
MIR_SL2~0 - MIR mode Select.
These bits setup the MIR operational mode when AM_FMT=1 and AD_MD2~0 set to
MIR mode. These values will be automatically loaded to IR_SL2~0, respectively.
