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 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.
