Write to buffer ABORTED.
Must write “Write-to-buffer
Abort Reset” command
sequence to return
to read mode.
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.
DQ7 and DQ15 may change simultaneously with
DQ5 and DQ13. Therefore, DQ7 and DQ15
should be verified.
If this flowchart location was reached because
DQ5 and DQ13 = “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 and DQ9 =1,
write the Write-Buffer-Programming-Abort-Reset
command. if DQ5 and DQ13 =1, write the Reset
command.

required for write buffer programming.
