Figure 10.23 shows an example of PWM mode 2 operation. In this example, synchronous
operation is designated for channels 0 and 1, TGRB_1 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
(TGRA_0 to TGRD_0, TGRA_1), to output a 5-phase PWM waveform. In this case, the value set
in TGRB_1 is used as the cycle, and the values set in the other TGRs as the duty.
