Notes:
1. When Sector Address is specified, any address in the selected sector is acceptable. However, when loading Write-Buffer
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

address locations with data, all addresses must fall within the selected Write-Buffer Page.
because DQ1= “1”, 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.
