Section 11 16-Bit Timer Pulse Unit (TPU)
Figure 11.23 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 cycle.
