Legend:
X = Don’t care.
RA = Read Address.
RD = Read Data.
PA = Program Address. Addresses latch on the rising edge of the
AVD# pulse or active edge of CLK, whichever occurs first.
PD = Program Data. Data latches on the rising edge of WE# or CE#
pulse, whichever occurs first.
SA = Sector Address. WS256N = A23–A14; WS128N = A22–A14;
WS064N = A21–A14.
BA = Bank Address. WS256N = A23–A20; WS128N = A22–A20;
WS064N = A21–A18.
CR = Configuration Register data bits D15–D0.
WBL = Write Buffer Location. Address must be within the same write
buffer page as PA.
WC = Word Count. Number of write buffer locations to load minus 1.

See
Table 8.1
for description of bus operations.
All values are in hexadecimal.
Shaded cells indicate read cycles.
Address and data bits not specified in table, legend, or notes are
don’t cares (each hex digit implies 4 bits of data).
Writing incorrect address and data values or writing them in the
improper sequence may place the device in an unknown state.
The system must write the reset command to return the device
to reading array data.
No unlock or command cycles required when bank is reading
array data.
Reset command is required to return to reading array data (or to
the erase-suspend-read mode if previously in Erase Suspend)
when a bank is in the autoselect mode, or if DQ5 goes high
(while the bank is providing status information) or performing
sector lock/unlock.
The system must provide the bank address. See
Autoselect
section for more information
.
Data in cycle 5 is 2230 (WS256N), 2232 (WS064N), or 2231
(WS128N).
10. See
Table 8.9
for indicator bit values.

9.
11. Total number of cycles in the command sequence is determined
by the number of words written to the write buffer.
12. Command sequence resets device for next command after write-
to-buffer operation.
13. System may read and program in non-erasing sectors, or enter
the autoselect mode, when in the Erase Suspend mode. The
Erase Suspend command is valid only during a sector erase
operation, and requires the bank address.
14. Erase Resume command is valid only during the Erase Suspend
mode, and requires the bank address.
15. Command is valid when device is ready to read array data or
when device is in autoselect mode. Address equals 55h on all
future devices, but 555h for WS256N/128N/064N.
16. Requires Entry command sequence prior to execution. Unlock
Bypass Reset command is required to return to reading array
data.
17. Requires Entry command sequence prior to execution. Secured
Silicon Sector Exit Reset command is required to exit this mode;
device may otherwise be placed in an unknown state.
18. Requires reset command to configure the Configuration Register.
