Set7.Reg3 - Sets Select Register (SSR)

RX_DM - Receiver Demodulation Mode.
TX_MM1~0 - Transmitter Modulation Mode 1~0
IR_MSP - IR Mode Select Pulse
When set to 1, the transmitter (IRTX) will send a 64
end operational mode. When IR front-end module uses mode select pin (MD) and
transmitter IR pulse (IRTX) to switch between high speed IR (such as FIR or MIR) and
low speed IR (SIR or ASK-IR), this bit should be used.
SIR_SL2~0 - SIR (Serial IR) mode select.
These bits are used to program the operational mode of the SIR front-end module.
These values of SIR_SL2~0 will be automatically loaded to pins of IR_SL2~0,
respectively, when (1) AM_FMT=1 (Automatic Format, in Set7.Reg7.Bit7); (2) the mode
of Advanced IR is set to SIR (AD_MD2~0, in Set0.Reg4.Bit7~0).
