9 / 14 page 9 April 21, 2004 U634H256 u: If the chip enable pulse width is less then ta(E) (see READ cycle) but greater than or equal to tw(E)SR, then the data may not be valid at the end of the low pulse, however the STORE or RECALL will still be initiated. v: 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 U634H256 performs a STORE or RECALL. w: E must be used to clock in the address sequence for the software controlled STORE and RECALL cycles.
