Figure 55. Externally Triggered Counter Reset and Start Combined with Single-action
Mode
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 ore both compare registers,
the trigger signal restarts the single actions. This mode can be used for frequency mea-
surements or as event counter with time gate (see combination mode 10).
Figure 56. Event Counter with Time Gate
The timer runs as timer/counter in mode 1, but its output T3O is used as output for the
Timer 2 output signal.
The Timer 3 runs as timer/counter in mode 2, but its output T3O is used as output for the
Timer 2 output signal.
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).
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 (SO) of the SSI is used to enable or disable the Timer
3 output. The SSI should be supplied with the toggle signal of Timer 2 (see combination
mode 12).
