Key Wake-Up Input Filter
this time interval is shorter than tKWSP, the majority voting logic may treat
the two consecutive pulses as a single valid pulse.
The filter is shared by all the KWU pins. Hence any valid triggering level
on any KWU pin is seen by the filter. The timing specification applies to
the input of the filter.
