The output compare functions can be used both for generating external events on the
OCMPi pins even if the input capture mode is also used.

successful comparison in order to control an output waveform or establish a new elapsed
timeout.
Forced compare output capability
When the FOLVi bit is set by software, the OLVLi bit is copied to the OCMPi pin. The OLVi bit
has to be toggled in order to toggle the OCMPi pin when it is enabled (OCiE bit = 1). The
OCFi bit is then not set by hardware, and thus no interrupt request is generated.
The FOLVLi bits have no effect in both one pulse mode and PWM mode.
