u: 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 wheter the U637256 performs a STORE

or RECALL.

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