NAME AND DESCRIPTION
RABT
RHIR.7
Abort Sequence Detected. Set whenever the HDLC controller sees 7 or
more ones in a row.
RCRCE
RHIR.6
CRC Error. Set when the CRC checksum is in error.
ROVR
RHIR.5
Overrun. Set when the HDLC controller has attempted to write a byte
into an already full receive FIFO.
RVM
RHIR.4
Valid Message. Set when the HDLC controller has detected and checked
a complete HDLC packet.
REMPTY
RHIR.3
Empty. A real-time bit that is set high when the receive FIFO is empty.
POK
RHIR.2
Packet OK. Set when the byte available for reading in the receive FIFO at
RHFR is the last byte of a valid message (and hence no abort was seen, no
overrun occurred, and the CRC was correct).
CBYTE
RHIR.1
Closing Byte. Set when the byte available for reading in the receive FIFO
at RHFR is the last byte of a message (whether the message was valid or
not).
OBYTE
RHIR.0
Opening Byte. Set when the byte available for reading in the receive
FIFO at RHFR is the first byte of a message.
Note: The RABT, RCRCE, ROVR, and RVM bits are latched and are cleared when read.
