CHAPTER 11 TIMER/EVENT COUNTER 2
11.9.4 Operation as PWM output
In PWM output, pulses with the duty ratio determined by the value set in the compare register (CR2n: n = 0, 1) are output
(see Figure 11-46).
This PWM output duty ratio can be varied in the range 1/256 to 255/256 in 1/256 units.
The control register settings are shown in Figure 11-47, the setting procedure in Figure 11-48, and the procedure for
varying the duty in Figure 11-49.
