Note 1: A write cycle can be initiated be CE or WE going low, whichever occurs last. The data is latched on the pos-
itive edge WE, whichever occurs first.
2: Data must be valid within 1000ns max. after a write cycle is initiated and must be stable at least until t
the positive edge of WE or CE, whichever occurs first.
