Notes
45. DQ5 switches to 1 when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits. See
for more information.
46. DQ7 and DQ2 require a valid address when reading status information. See
7.9
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.
