NOTES:
1. CE = V IH for the duration of the above timing (both write and read cycle) (Refer to Chip Enable Truth Table). Refer also to Truth Table II for appropriate BE controls.
2. "DATA OUT VALID" represents all I/O's (I/O 0 - I/O 35 ) equal to the semaphore value.

NOTES:
1. D OR = D OL = V IL , CE L = CE R = V IH . Refer to Truth Table II for appropriate BE controls.
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 be granted the semaphore flag.
