9 / 17 page  6.42 IDT7028L High-Speed 64K x 16 Dual-Port Static RAM Industrial and Commercial Temperature Ranges 9 Timing Waveform of Semaphore Read after Write Timing, Either Side(1) NOTES: 1. DOR = DOL = VIL, CEL = CER = VIH or both UB and LB = VIH (Refer to Chip Enable Truth Table). 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 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. Timing Waveform of Semaphore Write Contention(1,3,4) NOTES: 1. CE = VIH or UB and LB = VIH for the duration of the above timing (both write and read cycle) (Refer to Chip Enable Truth Table). 2. "DATAOUT VALID" represents all I/O's (I/O0 - I/O15) equal to the semaphore value.
