X = Don’t care
RA = Address of the memory to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed. Addresses latch on the falling edge of the WE# or CE# pulse,
PD = Data to be programmed at location PA. Data latches on the rising edge of the WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or erased. Address bits Amax–A16 uniquely select any sector.
WBL = Write Buffer Location. The address must be within the same write buffer page as PA.
WC = Word Count is the number of write buffer locations to load minus 1 and maximum value is 31 for word and byte mode.
