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.
