RX DMA error handing enable. If 0, the RX DMA interface
ignores error conditions in the IrDA receive section. If “1”,
the DMA interface stops and notifies the DMA block when
an error occurs. Errors include framing errors, receive
abort, and CRC mismatch.
TX DMA interface enable. Setting to “1” enables the
private DMA interface to the transmit FIFO.
RX DMA interface enable. Setting to “1” enables the
private DMA interface to the receive FIFO.
Reserved. Unknown During Read.
The state of the SIREN after synchronization. Read only.
The state of SIROUT output from the InfraRed block. Read
only.
The state of the TXD input to the InfraRed block from
UART2. Read only.
The state of the RXD output from the InfraRed block to
UART2. Read only.
