Set7.Reg6 - Infrared Module (Front End) Select 3 (IRM_SL3)
Set7.Reg7 - Infrared Module Control Register (IRM_CR)
AM_FMT - Automatic Format
A write to 1 will enable automatic format IR front-end module. These bits 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.
IRSL0D - Direction of IRSL0 Pin
Select function for IRRXH or IRSL0 because they share common pin and have different
input/output direction.
Reserved, write 0.
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.
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 are configured to Remote IR mode. These values will be
automatically loaded to IR_SL2~0, respectively.
