RX_BSY - Receiver Busy
Set to 1 when receiver is busy or active in process.
RX_IP - Receiver in Process
Set to 1 when receiver is in process.
LST_FE - Lost Frame End
Set to 1 when a frame end for an entire frame is lost. Clear to 0 when read this register.
RX_PD - Receiver Pulse Detected
Set to 1 when one or more than one remote pulses are detected. Clear to 0 when read
this register.
S_FEND - Set a Frame End
Write to 1 when wanting to terminate the frame; that is, the procedure of PIO command is
This bit should be set to 1, if used in PIO mode, to avoid transmitter underrun. Note that
this bit S_FEND is set to 1, that is, equivalent to TC (Terminal Count) in DMA mode. This
bit should therefore be set to 0 in DMA mode.
Reserved.
LB_SF - Last Byte Stay in FIFO
Set to 1 that indicates one or more than one frame end still stay in receiver FIFO.
RX_TO - Receiver FIFO or Frame Status FIFO time-out
Set to 1 when receiver FIFO or frame status FIFO occurs time-out
An Entire Frame = Write Frame Data (First) + Write S_FEND (Last)
