Externally Triggered Counter Reset and Start Combined with Single-action
Mode
Timer 3 – Mode 3:
Timer/Counter, Internal
Trigger Restart and Internal
Capture (with TOG2)
The counter is driven by an internal or external (T3I) clock source. The output toggle sig-
nal of Timer 2 resets the counter. The counter value before the reset is saved in the
capture register. If single-action mode is activated for one or both compare registers, the
trigger signal restarts the single actions. This mode can be used for frequency measure-
ments or as event counter with time gate (see “Combination Mode 10: Frequency
Measurement or Event Counter with Time Gate” on page 85).
Figure 56.
Event Counter with Time Gate
Timer 3 – Mode 4:
Timer/Counter
The timer runs as timer/counter in mode 1, but its output T3O is used as output for the
Timer 2 output signal.
Timer 3 – Mode 5:
Timer/Counter, External
Trigger Restart and External
Capture (with T3I Input)
The Timer 3 runs as timer/counter in mode 2, but its output T3O is used as output for the
Timer 2 output signal.
Timer 3 Modulator/Demodulator Modes
Timer 3 – Mode 6:
Carrier Frequency Burst
Modulation Controlled by
Timer 2 Output Toggle
Flip-Flop (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 via the
output toggle flip-flop. The output toggle flip-flop of Timer 2 is used to enable or disable
the Timer 3 output. Timer 2 can be driven by the toggle output signal of Timer 3 or any
other clock source (see “Combination Mode 11: Burst Modulation 1” on page 86).
