35.6.2.8.1 Event Capture Action on Events or I/Os

The compare and capture channels can be used as input capture channels to capture events from the Event System or I/O pins and give them a timestamp. This mode is selected when EVTCTRL.EVACT is configured either as OFF, RETRIGGER, COUNT or START. The following figure shows four capture events for one capture channel.

Figure 35-12. Input Capture Timing

The TC can detect capture overflow of the input capture channels: When a new capture event is detected while the Capture Interrupt flag (INTFLAG.MCx) is still set, the new timestamp will not be stored and INTFLAG.ERR will be set.
