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 set to Remote IR mode. These values will automatically
load to IR_SL2~0, respectively.
Reserved, write 0.
HRC_SL2~0 - High Speed Remote IR Mode Select.
These bits setup the operational mode of high speed remote IR front-end module when
AM_FMT=1 and .AD_MD2~0 set to Remote IR mode. These values will automatically
load to IR_SL2~0, respectively.
AM_FMT - Automatic Format
Write to 1 enables automatic format IR front-end module. This bit will affect the output of
IR_SL2~0, which is referred by IR front-end module selection (Set7.Reg4~6)
IRX_MSL - IR Receiver module Select
Select the receiver input path from the IR front end module if IR module has a separated
high speed and low speed receiver path. If the IR module has only one receiving path,
then this bit should be set to 0.
