Combination mode 10: Frequency measurement or event counter with time gate
Timer 2 mode 1/2:
12-bit compare counter / 8-bit compare counter and 4-bit prescaler
Timer 2 output mode 1/6: Timer 2 compare match toggles (TOG2) to the Timer 3
Timer 3 mode 3:
Timer / Counter; int. trigger restart & int. capture (with Timer 2 TOG2–signal)
The counter is driven by an external (T3I) clock source. The output signal (TOG2) of Timer 2 resets the counter. The
counter value before reset is saved in the capture register. If single-action mode is activated for one or both compare
registers, the trigger signal restarts also the single actions. This mode can be used for frequency measurements or as
event counter with time gate.

Combination mode 11: Burst modulation 1
Timer 2 mode 1/2:
12-bit compare counter / 8-bit compare counter and 4-bit prescaler
Timer 2 output mode 1/6: Timer 2 compare match toggles the output flip-flop (M2) to the Timer 3
Timer 3 mode 6:
Carrier frequency burst modulation controlled by Timer 2 output (M2)
The Timer 3 counter is driven by an internal or external clock source. Its compare- and compare mode registers must
be programmed to generate the carrier frequency with the output toggle flip-flop. The output toggle flip-flop (M2) of
Timer 2 is used to enable and disable the Timer 3 output. The Timer 2 can be driven by the toggle output signal of
Timer 3 (TOG3) or any other clock source.
