NOTES:
1. D OR = D OL = V IL , CE R = CE L = V IH .
2. All timing is the same for left and right ports. Port "A" may be either left or right port. "B" is the opposite from port "A".
3. This parameter is measured from R/ W A or SEM A going HIGH to R/ W B or SEM B going HIGH.
4. If t SPS is not satisfied, the semaphore will fall positively to one side or the other, but there is no guarantee which side will obtain the flag.
