X = Don’t care
RA = Address of the memory location to be read.
RD = Data read from location RA during read op eration.
PA = Address of the memory location to be programmed.
Addresses latch on the falling edge of the WE# or CE# pulse,
whichever happens later.
PD = Data to be programmed at location PA. Data latches on the
rising edge of WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be v erified (in autoselect mode) or
erased. Address bits A18–A12 uniquely select any sector.
