NOTES:
1. R/
W
is HIGH for Read Cycles
2. Device is continuously enabled.
CS
= LOW. This waveform cannot be used for semaphore reads.
3. Addresses valid prior to or coincident with
CS
transition LOW.
4.
OE
= LOW.
5. To access RAM,
CS
= LOW,
SEM
= H. To access semaphore,
CS
= HIGH and
SEM
= LOW.
6. This parameter is guaranteed by design but not tested.
