Figure 13.32 shows examples of PWM waveform output with 0% duty and 100% duty in
complementary PWM mode (for one phase). In this example, by setting the GRB_0 to a value
equal to or more than GRA_0, and H'0000 for the value of GRB_0, the waveform with a duty of
0% and 100% can be output. When buffer operation is also used, manipulation of the above
operation and modification of the duty can be done easily during operation. For details on buffer
operation, refer to section 13.4.8, Buffer Operation.
