DQ7 = Data?
DQ5 = 1?
DQ1 = 1?
Write to buffer ABORTED.
Must write “Write-to-buffer
Abort Reset” command
sequence to return
to read mode.
(Note 2)
(Note 3)
(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 10 and for command
sequences required for write buffer
programming.
