SIR_PLS - Send Infrared Pulse
Writing 1 to this bit will send a 2
to signal to SIR that the high speed infrared is still in. This bit will be auto cleared by
hardware.
TX_WT - Transmission Waiting
If this bit is set to 1, the transmitter will wait for TX FIFO to reach threshold level or
transmitter time-out before it begins to transmit data; this prevents short queues of data
bytes from transmitting prematurely. This is to avoid Underrun.
EN_DMA - Enable DMA
Enable DMA function for transmitting or receiving. Before using this, the DMA channel
should be selected first. If only RX DMA channel is set and TX DMA channel is disabled,
then the single DMA channel is used. In the single channel system, the bit of D_CHSW
(DMA channel swap, in Set 2.Reg2.Bit3) will determine if it is RX_DMA or TX_DMA
channel.
RTS, DTR
Functional definitions are the same as in legacy IR mode.
