Transitional Acquisition Mode
In Transitional Acquisition mode, the timing analyzer samples data at regular
intervals, but only stores data when there is a level transition on currently
assigned bits of a pod pair. Each time a level transition occurs on any of the
assigned bits, all bits of the pod pair are stored. A time tag is stored with
each stored data sample so the measurement can be reconstructed and
displayed later. If transitions are exceptionally far apart, the timer may
overflow. This does not generate a warning.

Conventional and Transitional Comparison
One issue when using transitional timing is how many transitions can be
stored. The number depends on the mode and frequency of transition
occurrence. The following overview explains the number of transitions
stored for each transitional timing mode and why.
