Timing Waveform of Semaphore Read after Write Timing, Either Side(1)
NOTE:
1. CE = VIH for the duration of the above timing (both write and read cycle).
2. “DATAOUT VALID” represents all I/O's (I/O0-I/O7) equal to the semaphore value.

NOTES:
1. DOR = DOL = VIL, CER = CEL = VIH, Semaphore Flag is released from both sides (reads as ones from both sides) at cycle start.
2. “A” may be either left or right port. “B” is the opposite port from “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 tSPS 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.
