toggling, the device has successfully completed the
program or erase operation. If it is still toggling, the de-
vice did not complete the operation successfully, and
the system must write the reset command to return to
reading array data.
The remaining scenario is that the system initially de-
termines that the toggle bit is toggling and DQ5 has
not gone high. The system may continue to monitor
the toggle bit and DQ5 through successive read cy-
cles, determining the status as described in the
previous paragraph. Alternatively, it may choose to
perform other system tasks. In this case, the system
must start at the beginning of the algorithm when it re-
turns to determine the status of the operation (top of
Figure 6).

Notes:
1. Read toggle bit twice to determine whether or not it is
toggling. See text.
2. Recheck toggle bit because it may stop toggling as DQ5
changes to “1”. See text.
