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 DQ5: Exceeded Timing Limits

on page 38 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.
