9.1 Interrupt Handling
The host can quickly determine which status registers in the four ports are causing an interrupt by reading one of
the unused addresses such as 0Ch, 0Dh, or 0Eh in any port.

Jitter Attenuator Limit Trip
. Set when the jitter attenuator FIFO reaches to
within 4 bits of its limit; useful for debugging jitter attenuation operation.
Receive Elastic Store Full.
Set when the receive elastic store buffer fills and a
frame is deleted.
Receive Elastic Store Empty.
Set when the receive elastic store buffer
empties and a frame is repeated.
CRC Resync Criteria Met.
Set when 915/1000 codewords are received in
error.
FAS Resync Criteria Met.
Set when three consecutive FAS words are
received in error.
CAS Resync Criteria Met.
Set when two consecutive CAS MF alignment
words are received in error.
