Note p: Once the software STORE or 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 (see READ CYCLE #2) but greater than or equal to t , 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-M performs a STORE or RECALL.

Note t: E must be used to clock in the address sequence for the Software STORE and RECALL cycles.
