Switching Waveforms
Read Cycle No.1 (Either Port Address Access)
[36, 37, 38]
Read Cycle No.2 (Either Port CE/OE Access)
[36, 39, 40]
Read Cycle No. 3 (Either Port)
[36, 38, 41, 42]
Notes:
36.R/W is HIGH for read cycles.
37.Device is continuously selected CE = V
IL
and UB or LB = V
IL
. This waveform cannot be used for semaphore reads.
38.OE = V
.
39.Address valid prior to or coincident with CE transition LOW.
40.To access RAM, CE = V
, UB or LB = V
, SEM = V
IH
. To access semaphore, CE = V
IH
, SEM = V
IL
.
41.R/W must be HIGH during all address transitions.
42.A write occurs during the overlap (t
SCE
or t
PWE
) of a LOW CE or SEM and a LOW UB or LB.
