Switching Waveforms
Notes
25. R/W is HIGH for read cycles.
26. Device is continuously selected. CE0 = VIL, CE1=VIH, and B0, B1, B2, B3, WA, BA are valid. This waveform cannot be used for semaphore reads.
27. OE = VIL.
28. Address valid prior to or coinciding with CE0 transition LOW and CE1 transition HIGH.
29. To access RAM, CE0 = VIL, CE1=VIH, B0, B1, B2, B3, WA, BA are valid, and SEM = VIH. To access semaphore, CE0 = VIH, CE1=VIL and SEM = VIL or CE0
and SEM=VIL, and CE1= B0 = B1 = B2 = B3, =VIH.
