To ensure the command has been accepted, the system software should check the status of DQ3 prior to and
following each subsequent sector erase command. If DQ3 is high on the second status check, the last
command might not have been accepted.
Table 12.2 on page 60
shows the status of DQ3 relative to the other status bits.
12.8
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
Write Buffer Programming Operation
on page 18
for more details.
Notes
1. DQ5 switches to ‘1’ when an Embedded Program or Embedded Erase 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. Data are invalid for addresses in a Program Suspended sector.
4. DQ1 indicates the Write to Buffer ABORT status during Write Buffer Programming operations.
5. The data-bar polling algorithm should be used for Write Buffer Programming operations. Note that DQ7# during Write Buffer
Programming indicates the data-bar for DQ7 data
for the LAST LOADED WRITE-BUFFER ADDRESS location
.
