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 EAC to standby (Read Mode) and the Status Register failed bits
are cleared. See
Write Buffer Programming on page 24
for more details.
Notes:
1. DQ5 switches to '1' when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits. See
for more information.
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
3. Data are invalid for addresses in a Program Suspended Line. All addresses other than the program suspended line can be read for valid data.
4. DQ1 indicates the Write-to-Buffer ABORT status during Write-Buffer-Programming operations.
5. Applies only to program operations.
