STK Control #ML0048
Rev 1.1
u: If the chip enable pulse width is less then t
a(E)
(see READ cycle) but greater than or equal to t
w(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.
