(2) Examples of PWM Mode Operation

Figure 10.22 shows an example of PWM mode 1 operation.

In this example, TGRA compare match is set as the TCNT clearing source, 0 is set for the TGRA

initial output value and output value, and 1 is set as the TGRB output value.

In this case, the value set in TGRA is used as the period, and the values set in TGRB registers as

the duty.

Figure 10.22 Example of PWM Mode Operation (1)

Figure 10.23 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.
