Switching Waveforms
Notes:
24. R/W is HIGH for read cycles.
25. Device is continuously selected CE = VIL. This waveform cannot be used for semaphore reads.
26. OE = VIL.
27. Address valid prior to or coincident with CE transition LOW.
28. To access RAM, CE = VIL, SEM = VIH. To access semaphore, CE = VIH, SEM = VIL.
