24.4.1 Rules for Single Edge Controlled PWM Outputs
24.4.2 Rules for Double Edge Controlled PWM Outputs
Five rules are used to determine the next value of a PWM output when a new cycle is
about to begin:

Capture Inputs. A transition on a capture pin can be configured to load
the corresponding Capture Register with the value of the Timer
Counter and optionally generate an interrupt. The PWM brings out 2
capture inputs.
