R/W is high for read cycles.
Device is continuously enabled, CS=VIL, UB or LB VIL. This waveform cannot be used for semaphore reads.
Addresses valid prior to or coincident with CS transition low.
OE = VIL
To access RAM, CS=VIL, UB or LB = VIL, SEM = VIH. To access semaphore, CS = VIH, SEM = VIL. Refer to Table 1.
