Examples of PWM Mode: Figure 10.29 shows examples of operation in PWM mode. In PWM
mode TIOCA becomes an output pin. The output goes to 1 at compare match with GRA, and to 0
at compare match with GRB.
In the examples shown, TCNT is cleared by compare match with GRA or GRB. Synchronized
operation and free-running counting are also possible.
