This register defines frequency range of receiver of remote IR.
Bit 7~5: RX_FR2~0 - Receiver Frequency Range 2~0.
These bits select the input frequency range of the receiver. It is implemented through a
band pass filter, i.e., only the input signals whose frequency lies in the range defined in
this register will be received.

Selects the operation frequency of receiver.
