STK12C68-IM
Note p: Once the software STOREor RECALL cycle is initiated, it completes automatically, ignoring all inputs.
Note q: Noise on the E pin may trigger multiple read cycles from the same address and abort the address sequence.
Note r:
If the Chip Enable Pulse Width is less than t
ELQV
(see READ CYCLE #2) but greater than or equal to t
ELEHN
, then the data may not be valid at the end
of the low pulse, however the STORE or RECALL will still be initiated.
Note s:
W must be HIGH when E is LOW during the address sequence in order to initiate a nonvolatile cycle. G may be either HIGH or LOW throughout.
Addresses #1 through #6 are found in the MODE SELECTION table. Address #6 determines whether the STK12C68-IM performs a STOREor RECALL
Note t:
E must be used to clock in the address sequence for the Software STORE and RECALL cycles.
