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.

CRC Resync Criteria Met. Set when 915/1000 codewords are received in
error.
FASRC
1
FAS Resync Criteria Met. Set when three consecutive FAS words are
received in error.
CASRC
0
CAS Resync Criteria Met. Set when two consecutive CAS MF alignment
words are received in error.
