30.8.6 Recoverable Fault B Configuration
Name: FCTRLB
Offset: 0x10
Reset: 0x00000000
Property: Enable-Protected, Write-Protected
z Bits 31:28 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always write these bits to
zero when this register is written. These bits will always return zero when read.
z Bits 27:24 – FILTERVAL[3:0]: Fault B 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.
z Bits 23:16 – BLANKVAL[7:0]: Fault B Blanking Time
These bits are used to ignore potential glitches after selectable waveform edge is detected. The edge selection is
available in BLANK bits (FCTRLB.BLANK). When enabled, the fault input source is internally disabled during
BLANKVAL* prescaled GCLK_TCC periods after the detection of the edge.
z Bit 15 – Reserved
This bit is unused and reserved for future use. For compatibility with future devices, always write this bit to zero
when this register is written. This bit will always return zero when read.
z Bits 14:12 – CAPTURE[2:0]: Fault B Capture Action
These bits select the capture and Fault B interrupt/event conditions, as defined in table below.
