Figure 10-26 shows an example of PWM mode 2 operation.
In this example, synchronous operation is designated for channels 0 and 1, TGR1B compare match
is set as the TCNT clearing source, and 0 is set for the initial output value and 1 for the output
value of the other TGR registers (TGR0A to TGR0D, TGR1A), to output a 5-phase PWM
waveform.
In this case, the value set in TGR1B is used as the cycle, and the values set in the other TGRs as
the duty.
