Reserved. Reads 0.
More Data Available. A 1 indicates that if the FIFO is
read again, valid data will be returned. A 0 indicates no
more data is available.
Receive FIFO Valid Data. A 1 indicates the information
read from the FIFO is valid. A 0 indicates the FIFO was
empty and no information was available.
Receive FIFO Data Type. A 0 indicates
FRM_HR_DATA[7:0] is data. A 1 indicates
FRM_HR_DATA[7:0] is status information.

are defined below.
FIFO Overflow. A 1 indicates the FIFO overflowed.
End of Packet. A 1 indicates end of packet (normal
packet).
HDLC CRC Error. A 1 indicates a CRC error was
detected.
HDLC Abort. A 1 indicates an abort was received.
HDLC Idle. A 1 indicates idle (as defined by HDLC proto-
col) condition detected.
Complete Byte Status. 111 indicates the last data
received was a complete byte.
These bits should be ignored if EOP is 0.
