IRTXDRQSL (bit 7-bit 4): Transmitter DMA channel A through D selection when high speed infrared
(FIR/MIR) is used and enable DMA channel. Note that these bits is used in two DMA channels.
IRRXDRQSL(bit 3-bit 0): Receiver or Transmitter DMA channel A through selection when high speed
infrared (FIR/MIR) is used and enable DMA channel. Note that these bits act as RX DMA channel
