Refer to Figure 4 for the following discussion. Whenever the
system initially begins reading toggle bit status, it must read
l/07 - l/00 at least twice in a row to determine whether a
toggle bit is toggling. Typically, a system would note and
store the value of the toggle bit after the first read. After the
second read, the system would compare the new value of the
toggle bit with the first. If the toggle bit is not toggling, the
device has completed the program or erase operation. The
system can read array data on l/07 - l/00 0n the following
read cycle.
However, if after the initial two read cycles, the system
determines that the toggle bit is still toggling, the system also
should note whether the value of l/Os is high (see the section
on l/Os). If it is, the system should then determine again
whether the toggle bit is toggling, since the toggle bit may
have stopped toggling just as l/Os went high. If the toggle bit
is no longer toggling, the device has successfully completed
the program or erase operation. If it is still toggling, the
device 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 determines
that the toggle bit is toggling and l/Os has not gone high. The
system may continue to monitor the toggle bit and l/Os
through successive read cycles, 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
returns to determine the status of the operation (top of Figure
4).
