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.
