Information

Notes:

1. DQ5 switches to ‘1’ when an Embedded Program, Embedded Erase, or Write-to-Buffer operation has exceeded the

maximum timing limits. Refer to the section on DQ5 for more information.

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

further details.

3. The Data# Polling algorithm should be used to monitor the last loaded write-buffer address location.

4. DQ1 switches to ‘1’ when the device has aborted the write-to-buffer operation.
