Notes
1. When Sector Address is specified, any address in the selected sector is acceptable. However, when loading Write-Buffer address
2. DQ7 may change simultaneously with DQ5. Therefore, DQ7 should be verified.
3. If this flowchart location was reached because DQ5= 1, then the device FAILED. If this flowchart location was reached because DQ1= 1,
4. See
locations with data, all addresses must fall within the selected Write-Buffer Page.
then the Write to Buffer operation was ABORTED. In either case, the proper reset command must be written before the device can begin
another operation. If DQ1= 1, write the Write-Buffer-Programming-Abort-Reset command. if DQ5= 1, write the Reset command.
