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.
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 Tables
16
and
17
for command
sequences required for write buffer
programming.
