Table 13.
Command Definitions (x8 Mode, BYTE# = V
IL
)
Legend:
X = Don’t care
RA = Read Address of the memory location to be read.
RD = Read Data read from location RA during read operation.
PA = Program Address. Addresses latch on the falling edge of the WE#
or CE# pulse, whichever happens later.
PD = Program Data for location PA. Data latches on the rising edge of
WE# or CE# pulse, whichever happens first.
SA = Sector Address of sector to be verified (in autoselect mode) or
erased. Address bits A21–A15 uniquely select any sector.
WBL = Write Buffer Location. Address must be within the same write
buffer page as PA.
BC = Byte Count. Number of write buffer locations to load minus 1.

See
Table 1
for description of bus operations.
All values are in hexadecimal.
Except for the read cycle and the fourth cycle of the autoselect
command sequence, all bus cycles are write cycles.
During unlock cycles, when lower address bits are 555 or AAAh
as shown in table, address bits higher than A11 (except where BA
is required) and data bits higher than DQ7 are don’t cares.
No unlock or command cycles required when device is in read
mode.
The Reset command is required to return to the read mode (or to
the erase-suspend-read mode if previously in Erase Suspend)
when the device is in the autoselect mode, or if DQ5 goes high
while the device is providing status information.
The fourth cycle of the autoselect command sequence is a read
cycle. Data bits DQ15–DQ8 are don’t care. See
Autoselect
Command Sequence on page 28
for more information.
The device ID must be read in three cycles. The data is 01h for
top boot and 00h for bottom boot
If WP# protects the top two address sectors, the data is 98h for
factory locked and 18h for not factory locked. If WP# protects the
bottom two address sectors, the data is 88h for factory locked and
08h for not factor locked.

10. The data is 00h for an unprotected sector group and 01h for a
protected sector group.
11. The total number of cycles in the command sequence is
determined by the number of bytes written to the write buffer. The
maximum number of cycles in the command sequence is 37,
including "Program Buffer to Flash" command.
12. Command sequence resets device for next command after
aborted write-to-buffer operation.
13. The Unlock Bypass command is required prior to the Unlock
Bypass Program command.
14. The Unlock Bypass Reset command is required to return to the
read mode when the device is in the unlock bypass mode.
15. The system can 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.
16. The Erase Resume command is valid only during the Erase
Suspend mode.
17. Command is valid when device is ready to read array data or when
device is in autoselect mode.
