Error Types and Clearing Procedures
DQ1: Write-to-Buffer Abort
DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these conditions DQ1 produces a 1.
The system must issue the Write-to-Buffer-Abort-Reset command sequence to return the EAC to standby
(read mode) and the Status Register failed bits are cleared. See
more details.
Notes:
1. DQ5 switches to '1' when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits. See
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
3. Data are invalid for addresses in a Program Suspended Line.
4. DQ1 indicates the Write-to-Buffer ABORT status during Write-Buffer-Programming operations.
There are three types of errors reported by the embedded operation status methods. Depending on the error
type, the status reported and procedure for clearing the error status is different. Following is the clearing of
error status:

If an ASO was entered before the error the device remains entered in the ASO awaiting ASO read or
a command write.
If an erase was suspended before the error the device returns to the erase suspended state awaiting
flash array read or a command write.
Otherwise, the device will be in standby state awaiting flash array read or a command write.
