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).
