Timer 3 – Mode 2:

Timer/Counter, External

Trigger Restart and External

Capture (with T3I Input)

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 cur-

rent counter value into the capture register, reset the counter and restart it. The edge

can be selected by the programmable 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.
