10.18 DQ1: Write-to-Buffer Abort
DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these conditions DQ1 produces a
1.
The system must issue the Write-to-Buffer-Abort-Reset command sequence to return the device to reading
array data. See
for more details.

Notes
1. DQ5 switches to
1
when an Embedded Program, Embedded Erase, or Write-to-Buffer operation 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 aborts the write-to-buffer operation.
