once it has been exceeded for the RECALL to function properly.
s:
Noise on the E pin may trigger multiple READ cycles from the same address and abort the address sequence.
t:
If the Chip Enable Pulse Width is less than t
a(E)
(see Read Cycle) but greater than or equal t
w(E)SR
, than the data may not be valid at
the end of the low pulse, however the STORE or RECALL will still be initiated.
The software sequence is clocked with E controlled READs.
Once the software controlled STORE or RECALL cycle is initiated, it completes automatically, ignoring all inputs.
Note that STORE cycles (but not RECALL) are inhibited by V
CC
< V
SWITCH
(STORE inhibit).
