These registers indicate whether a change of frame alignment, a framing bit
error, a bit error event, or a severely errored framing event generated an
interrupt. These registers also indicate whether a mimic framing pattern was
detected or whether there was a change in the framing state of the frame
circuitry.
COFAI,FERI,BEEI,SFEI:
A logic 1 in the status bit positions COFAI, FERI, BEEI, and SFEI indicate that
the occurrence of the corresponding event generated an interrupt; a logic 0 in
the status bit positions COFAI, FERI, BEEI, and SFEI indicate that the
corresponding event did not generate an interrupt.
MFPI:
A logic 1 in the MFPI status bit position indicates that the assertion or
deassertion of the mimic detection indication has generated an interrupt; a
logic 0 in the MFPI bit position indicates that no change in the state of the
mimic detection indication occurred.
INFRI:
A logic 1 in the INFRI status bit position indicates that a change in the state of
the frame alignment circuitry generated an interrupt; a logic 0 in the INFRI
status bit position indicates that no state change occurred.
MFP,INFR:
The bit position MFP and INFR indicate the current state of the mimic
detection and of the frame alignment circuitry.
