Writing to this register has immediate effect and should only be done when
the input capture modes of channels (n) and (n+1) are disabled. Failure to
do so could result in a missing valid signal.
Writing to this register has immediate effect and should only be done when
the fault control is disabled. Failure to do so could result in a missing fault
detection.
Fault input filter. FFVAL[3:0] bits select the filter value for the fault input.
The fault filter is disabled when FFVAL[3:0] is zero.

Channel (n+1) input filter. CH(n+1)FVAL[3:0] bits select the filter value for the channel (n+1) input.
The channel (n+1) filter is disabled when CH(n+1)FVAL[3:0] is zero.
Channel (n) input filer. CH(n)FVAL[3:0] bits select the filter value for the channel (n) input.
The channel (n) filter is disabled when CH(n)FVAL[3:0] is zero.
