Reading Toggle Bits DQ6/DQ2
Refer to
Figure 24
for the following discussion. Whenever the system initially begins reading tog-
gle bit status, it must perform two immediately consecutive reads of DQ7–DQ0 to determine
whether a toggle bit is toggling. Typically, the 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 completed the program or erase
operation. The system can read array data on DQ7–DQ0 on the following read cycle.
However, if after the initial two immediately consecutive read cycles, the system determines that
the toggle bit is still toggling, the system also should note whether the value of DQ5 is high (See
DQ5: Exceeded Timing Limits
on page 60
). 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 DQ5
went high. If the toggle bit is no longer toggling, the device 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
DQ5 has not gone high. The system may continue to monitor the toggle bit and DQ5 through suc-
cessive 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 7
).
