Figure 5-27. Counter Reset with Compare Register 2 and Toggle with Start
Figure 5-28. Single Action of Compare Register 1
Timer 3 – Mode 2:
The counter is driven by an internal clock source. After starting with T3R, the first edge from the
external input T3I starts the counter. The following edges at T3I load the current counter value
into the capture register, reset the counter and restart it. The edge can be selected by the pro-
grammable edge decoder of the timer input stage. If single-action mode is activated for one or
both compare registers the trigger signal restarts the single action.
