Bit
[7:6] These two bits decide preamble length to be transmitted at the
beginning of each frame in FIR mode. The default value of
PLR[7:6] = '00' which is equal to 16 preambles.

Note: Tx Trigger level value means how many data are empty.
[3:0] Number of start flags in MIR mode. The number of start flags to be
transmitted at the beginning of a frame is equal to the IrDA_PLR
[3:0] value. The minimum value is 3.
Bit
[7:0] Received data (If read data)
Data to transmit (If write data)
Bit
[7:0] The total number of data bytes remaining in Tx FIFO
Bit
[7:0] The total number of data bytes remaining in Rx FIFO.
