Figure 10.18 Example of Cascaded Operation (1)
Figure 10.19 illustrates the operation when TCNT_2 overflow/underflow counting has been set for
TCNT_1 and phase counting mode has been designated for channel 2.
TCNT_1 is incremented by TCNT_2 overflow and decremented by TCNT_2 underflow.

10.4.5 PWM
Modes
In PWM mode, PWM waveforms are output from the output pins. The output level can be selected
as 0, 1, or toggle output in response to a compare match of each TGR.
TGR registers settings can be used to output a PWM waveform in the range of 0% to 100% duty
cycle.
Designating TGR compare match as the counter clearing source enables the period to be set in that
register. All channels can be designated for PWM mode independently. Synchronous operation is
also possible.
