(2) Examples of PWM Mode Operation
Figure 18.10 shows examples of PWM mode operation.
When PWM mode is set, the TGIOA pin is automatically set as an output pin. The TGIOA pin
outputs 1 on a GRA compare match and outputs 0 on a GRB compare match. The TGIOB pin
always functions as an I/O pin for the relevant port.
In the examples shown in the figure, GRA and GRB compare matches are set as the TRGCNT
clearing source. The initial value of TGIOA differs according to the counter clearing source. The
correspondence between counter clearing sources and initial values is shown in table 18.5.
