Trigger and Queue Interaction Examples
Trigger events that occur during freeze are not captured. When a trigger event is pending
for queue 2 before freeze begins, that trigger event is remembered when the freeze is
passed. Similarly, when freeze occurs while queue 2 is suspended, after freeze, queue 2
resumes execution as soon as queue 1 is finished.
Situations 12 through 19 (Figure 13-36 to Figure 13-43) show examples of all of the freeze
situations.
