Table 6. Write Operation Status

Notes:

1. DQ5 switches to 1 when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits.

See DQ5: Exceeded Timing Limits‚ on page 21 for more information.

2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further

details.

Notes:

2. Minimum DC input voltage on pins A9, OE#, and RESET# is –0.5 V. During voltage transitions, A9, OE#, and RESET# may

overshoot to 12.5 V for periods up to 20 ns.

3. No more than one output may be shorted to ground at a time. Duration of the short circuit should not be greater than one

second.

Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections

of this data sheet is not implied. Exposure of the device to absolute maximum rating conditions for extended periods may

affect device reliability.
