While in PWM mode and the Timer2 prescaler is configured to 1:1, the duty cycle of
the PWM output is as expected. When the Timer2 prescaler is changed to a value other
than 1:1, while T2PR = 0 (PWM resolution of two bits), the expected
duty cycle is wrong. The corrected duty cycle values are shown in the table below.
| Prescaler/CCPR | 0 | 1 | 2 | 3 | 4 |
|---|---|---|---|---|---|
| 1:1 | 0% | 25% | 50% | 75% | 100% |
| 1:2 | 50% | 75% | 50% | 75% | 100% |
| 1:4...1:128 | 75% | 75% | 75% | 75% | 100% |
