Figure 14.35 shows an example of PWM waveform output with 0% duty and 100% duty in
complementary PWM mode (for one phase).
In this figure, GRB_0 is set to a value equal to or greater than GRA_0 and H'0000. The waveform
with a duty cycle of 0% and 100% can be output. When buffer operation is used together, the duty
cycles can easily be changed, including the above settings, during operation. For details on buffer
operation, refer to section 14.4.9, Buffer Operation.
