Bits 27:24 – FILTERVAL[3:0]: Recoverable Fault n Filter Value
These bits define the filter value applied on MCEx (x=0,1) event input line. The value must be set to zero
when MCEx event is used as synchronous event.
Bits 23:16 – BLANKVAL[7:0]: Recoverable Fault n Blanking Value
These bits determine the duration of the blanking of the fault input source. Activation and edge selection
of the blank filtering are done by the BLANK bits (FCTRLn.BLANK).
When enabled, the fault input source is internally disabled for BLANKVAL* prescaled GCLK_TCC periods
after the detection of the waveform edge.
Bits 14:12 – CAPTURE[2:0]: Recoverable Fault n Capture Action
These bits select the capture and Fault n interrupt/event conditions.
