Sixteen Zero Detect. Set when a string of 16 consecutive 0s has
been received at RPOS and RNEG.
RESF
RIR.4
Receive Elastic Store Full. Set when the elastic store buffer
fills and a frame is deleted.
RESE
RIR.3
Receive Elastic Store Empty. Set when the elastic store buffer
empties and a frame is repeated.
SEFE
RIR.2
Severely Errored Framing Event. Set when 2 out of 6 framing
bits are received in error.
B8ZS
RIR.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 CCR2.2.
FBE
RIR.0
Frame Bit Error. Set when a Ft (D4) or FPS (ESF) framing bit
is received in error.
Note: If the transmit elastic store slips, both RIR.4 and RIR.3 will be set.
