COMMAND DEFINITIONS
Writing specific address and data commands or
sequences into the command register initiates device
operations.
ister command sequences. Writing incorrect address
and data values or writing them in the improper
sequence resets the device to reading array data.
All addresses are latched on the falling edge of WE# or
CE#, whichever happens later. All data is latched on
the rising edge of WE# or CE#, whichever happens
first. Refer to the appropriate timing diagrams in
Characteristics” on page
Reading Array Data
The device is automatically set to reading array data
after device power-up. No commands are required to
retrieve data. The device is also ready to read array
data after completing an Embedded Program or
Embedded Erase algorithm.
After the device accepts an Erase Suspend command,
the device enters the Erase Suspend mode. The
system can read array data using the standard read
timings, except that if it reads at an address within
erase-suspended sectors, the device outputs status
data. After completing a programming operation in the

Suspend/Erase Resume Commands” on page 26

The system must issue the reset command to re-
enable the device for reading array data if DQ5 goes
high, or while in the autoselect mode. See

Reset Command
Writing the reset command to the device resets the
device to reading array data. Address bits are don’t
care for this command.
The reset command may be written between the
sequence cycles in an erase command sequence
before erasing begins. This resets the device to
reading array data. Once erasure begins, however, the
device ignores reset commands until the operation is
complete.
The reset command may be written between the
sequence cycles in a program command sequence
