z: 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 U630H16P performs a

STOREor RECALL.

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