(Note 1)
Notes:
1. When Sector Address is specified, any address in
the selected sector is acceptable. However, when
loading Write-Buffer address locations with data, all
addresses must fall within the selected Write-Buffer
Page.
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”, 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.
4. See Table 34 and Table 35 for command sequences
required for write buffer programming.
