Legend:
X = Don’t care
RA = Address of the memory location 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,
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 verified (in autoselect mode)
or erased. Address bits A20–A16 select a unique sector.
SGA = Address of the sector group to be verified. Address
bits A20–A18 select a unique sector group.
Notes:
