1: Enable counting accumulation of
errors
1: Disables 8b/10b decode errors
from being counted or flagged on
LOCK pin
1: clears errors in both the current and
previous state of teh errors count
0: Number of errors in current run
1: Number of errors within the
selected timing window
1: Disable exiting NORMAL state
when the number of errors exceeds
the error threshold
Error threshold above which part
stops transmittion of data — LSB
