MON1_B1E1I:
The MON1_B1E1I bit indicates the status of the interrupt generated when a change in the
status of the comparison has been detected on the B1/E1 bytes. The MON1_B1E1I is set
high when the monitor is in the synchronized state and when the status change is detected
on either the B1 or E1 bytes. For example, if a mismatch is detected and the previous
comparison was a match, the MON1_B1E1I bit will be set high. But if a mismatch is detected
and the previous comparison was a mismatch, the MON1_B1E1I bit will keep its previous
value. This bit is independent of MON1_B1E1E, and is cleared after it’s been read.
