Reset Command
Writing the reset command resets the device to the read or erase-suspend-read mode. Address bits are don’t
cares for this command.
The reset command may be written between the cycles in an erase command sequence before erasing
begins. This resets the device to the read mode. However, once erasure begins, the device ignores the reset
commands until the operation is complete.
The reset command may be written between the cycles in a program command sequence before
programming begins. This resets the device to the read mode. If the program command sequence is written
while the device is in the Erase Suspend mode, writing the reset command returns the device to the erase-
suspend-read mode. However, once programming begins, the device ignores the reset commands until the
operation is complete.
The reset command may be written between the cycles in an autoselect command sequence. Once in the
autoselect mode, the reset command must be written to exit the autoselect mode and return to the read
mode.
If DQ5 goes high during a program or erase operation, writing the reset command returns the device to the
read mode or erase-suspend-read-mode if the device was in Erase Suspend. When the reset command is
written, before the embedded operation starts, the device requires t
RR
before it returns to the read or erase-
suspend-read mode.

Advanced Sector Protection/Unprotection
The Advanced Sector Protection/Unprotection feature disables or enables programming or erase operations
in any or all sectors and can be implemented through software and/or hardware methods, which are
independent of each other. This section describes the various methods of protecting data stored in the
memory array. An overview of these methods in shown in
