4. 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
Automatic Program or Automatic 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 Erase
Suspend mode, the system may once again read array data with the same exception. See
Erase Suspend/Erase Resume Commands” for more information on this mode. The system
must issue the reset command to re-enable the device for reading array data if Q5 goes high,
or while in the auto select mode. See the "Reset Command" section, next.
5. RESET COMMAND
Writing the reset command to the device resets the device to reading array data. Addresses
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 before programming begins. This resets
the device to reading array data (also applies to programming in Erase Suspend mode). Once
programming begins, however, the device ignores reset commands until the operation is
complete. The reset command may be written between the sequence cycles in an SILICON ID
READ command sequence. Once in the SILICON ID READ mode, the reset command must
be written to return to reading array data (also applies to SILICON ID READ during Erase
Suspend). If Q5 goes high during a program or erase operation, writing the reset command
returns the device to reading array data (also applies during Erase Suspend).
