Legend:
BA = Address of the bank that is being switched to autose-
lect mode, is in bypass mode, or is being erased. Deter-
mined by A18 and A17, see Tables 11 and 12 for more
detail.
PA = Program Address (A18:A0). Addresses latch on the
falling edge of the WE# or CE# pulse, whichever hap-
pens later
PD = Program Data (DQ31:DQ0) written to location PA.
Data latches on the rising edge of WE# or CE# pulse,
whichever happens first.
RA = Read Address (A18:A0).
RD = Read Data (DQ31:DQ0) from location RA.
SA = Sector Address (A18:A11) for verifying (in autoselect
mode), erasing, or applying security commands.
WD = Write Data. See “Configuration Register” definition
X= Don’t care
Notes:
1. See Table 1 for description of bus operations.
2. All values are in hexadecimal.
3. Shaded cells in table denote read cycles. All other cycles
are write operations.
4. During unlock cycles, (lower address bits are 555 or
2AAh as shown in table) address bits higher than A11
(except where BA is required) and data bits higher than
DQ7 are don’t cares.
