SYMBOL

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