DQ5 has not gone high. The system may continue to monitor the toggle bit and DQ5 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 11.2 on page 37).
Figure 11.2 Toggle Bit Algorithm
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.
