Each event manager (EVA and EVB) has three capture units, and each is associated with a
capture input pin. Each capture unit can choose GP timer 1 or 2 for EVA, and GP timer 3 or 4 for
EVB as its time base. The value of GP timer 1 or 2 (EVA) and GP timer 3 or 4 (EVB) is captured
and stored in the corresponding 2-level-deep FIFO stack when a specified transition is detected
on a capture input pin.
