Set7.Reg2 - Remote Infrared Config Register (RIR_CFG)
If the bit value is set to 0, the high pulse will be transmitted/received. If the bit value is set to 1, then
no energy will be transmitted/received.
SMP_M - Sampling Mode.
To select receiver sampling mode.
When set to 0 then uses T-period sampling, that the T-period is programmed IR baud rate.
When set to 1, programmed baud rate will be used to do oversampling.
