COFA
RIR1.7
Change of Frame Alignment. Set when the last resync
resulted in a change of frame or multiframe alignment.
8ZD
RIR1.6
Eight Zero Detect. Set when a string of at least eight
consecutive zeros (regardless of the length of the string) have
been received at RPOS and RNEG.
16ZD
RIR1.5
Sixteen Zero Detect. Set when a string of at least sixteen
consecutive zeros (regardless of the length of the string) have
been received at RPOS and RNEG.
RESF
RIR1.4
Receive Elastic Store Full. Set when the receive elastic
store buffer fills and a frame is deleted.
RESE
RIR1.3
Receive Elastic Store Empty. Set when the receive elastic
store buffer empties and a frame is repeated.
SEFE
RIR1.2
Severely Errored Framing Event. Set when 2 out of 6
framing bits (Ft or FPS) are received in error.
B8ZS
RIR1.1
B8ZS Code Word Detect. Set when a B8ZS code word is
detected at RPOS and RNEG independent of whether the
B8ZS mode is selected or not via CCR2.6. Useful for
automatically setting the line coding.
