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 of CE or WE, whichever occurs rst
Note 2: Data must be valid within 1000ns max. after a write cycle is initiated and must be stable at least until tDH
after the positive edge of WE or CE, whichever occurs rst.
