DIS_BACK - Disable Backward Operation
A write to 1 disables backward legacy IR mode. When operating in legacy SIR/ASK-IR
mode, this bit should be set to 1 to avoid backward operation.
Reserved, write 0.
PR_DIV1~0 - Pre-Divisor 1~0.
These bits select pre-divisor for external input clock 24M Hz. The clock goes through the
pre-divisor, then input to baud rate divisor of IR.
RX_FSZ1~0 - Receiver FIFO Size 1~0
These bits setup receiver FIFO size when FIFO is enable.
TX_FSZ1~0 - Transmitter FIFO Size 1~0
These bits setup transmitter FIFO size when FIFO is enable.
