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.
Cyclic Sense Timing
Forced Wake-up - Wake-up caused by a forced wake-up
LIN Wake-up - Wake-up caused by a LIN wake-up
L5 Wake-up - Wake-up caused by a state change of the L6 Input
L4 Wake-up - Wake-up caused by a state change of the L5 Input
L3 Wake-up - Wake-up caused by a state change of the L4 Input
