Note m: Measured with W and NE both returned high, and G returned low. STORE cycles are inhibited below 4.0V.
Note n: Once tWC has been satisfied by NE, G, W and E, the STORE cycle is completed automatically. Any of NE, G, W or E may be used to terminate
the STORE initiation cycle.
Note o: If E is low for any period of time in which W is high while G and NE are low, then a RECALL cycle may be initiated.
