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.
FOLVLi bits have no effect in both one pulse mode and PWM mode.
