CRCERR[9:8]:
The CRCERR[9:8] register bits contain the two most significant bits of the 10-
bit CRC error counter value, which is updated every second.
This CRC error count is distinct from that of PMON because it is guaranteed to
be an accurate count of the number of CRC errors in one second; whereas,
PMON relies on externally initiated transfers which may not be one second apart.
