Note r:
Measured with W and NE both high, and G and E low.
Once tNLNH has been satisfied by NE, G, W and E, the RECALL cycle is completed automatically. Any of NE, G or E may be used to terminate
the RECALL initiation cycle.
If W is low at any point in which both E and NE are low and G is high, then a STORE cycle will be initiated instead of a RECALL.
