38.5.12 Events

The AC can generate the following output events:

  • Comparator (COMP0, COMP1): Generated as a copy of the comparator status
  • Window (WIN0): Generated as a copy of the window inside/outside status

Writing a one to an Event Output bit in the Event Control Register (EVCTRL.xxEO) enables the corresponding output event. Writing a zero to this bit disables the corresponding output event. See Event System (EVSYS) from Related Links for details on how to configure the Event System.

The AC can take the following action on an input event:

  • Start comparison (START0, START1): Start a comparison

Writing a one to an Event Input bit into the Event Control register (EVCTRL.COMPEIx) enables the corresponding action on an input event. Writing a zero to this bit disables the corresponding action on an input event. Note that if several events are connected to the AC, the enabled action will be taken on any of the incoming events. See Event System (EVSYS) from Related Links for details on how to configure the Event System.

When EVCTRL.COMPEIx is one, the event will start a comparison on COMPx after the start-up time delay. In normal mode, each comparator responds to its corresponding input event independently. For a pair of comparators in window mode, either comparator event will trigger a comparison on both comparators simultaneously.
