Forced Wake-up Multiplicator - Configures the multiplicator for the forced wake-up. The selected multiplicator (FWM!=0) will
force a wake-up every FWM x CST ms. With this implementation, Forced and Cyclic wake-up can be performed in parallel
with the cyclic sense period <= the forced wake-up period.
