IR_MSP - IR Mode Select Pulse
When set to 1, the transmitter (IRTX) will 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 between high speed IR (such as FIR or MIR) and
low speed IR (SIR or ASK-IR), this bit should be used.
SIR_SL2~0 - SIR (Serial IR) mode select.
These bits are used to program the operational mode of the SIR front-end module.
These values of SIR_SL2~0 will be automatically loaded to pins of IR_SL2~0,
respectively, when (1) AM_FMT=1 (Automatic Format, in Set7.Reg7.Bit7); (2) the mode
of Advanced IR is set to SIR (AD_MD2~0, in Set0.Reg4.Bit7~0).
Reserved, write 0.
AIR_SL2~0 - ASK-IR Mode Select.
These bits setup the operational mode of ASK-IR front-end module when AM_FMT=1
and AD_MD2~0 are configured to ASK-IR mode. These values will be automatically
loaded 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 are configured to FIR mode. These values will be automatically loaded 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 are
configured to MIR mode. These values will be automatically loaded to IR_SL2~0,
respectively.

LRC_SL2~0 - Low Speed Remote IR mode select.
These bits setup the operational mode of low speed remote IR front-end module when
AM_FMT=1 and AD_MD2~0 are configured to Remote IR mode. These values will be
automatically loaded to IR_SL2~0, respectively.
