Set7.Reg7 - Infrared Module Control Register (IRM_CR)
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.
AM_FMT - Automatic Format
A write to 1 will enable automatic format IR front-end module. These 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 the
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.
