Switching Waveforms
Notes:
15. R/W is HIGH for read cycle.
16. Device is continuously selected CE = LOW and OE = LOW. This waveform cannot be used for semaphore reads.
17. Address valid prior to or coincident with CE transition LOW.
18. CEL = L, SEM = H when accessing RAM. CE = H, SEM = L when accessing semaphores.
