Offset: 0x18
Reset: 0x00000000
Property: Enable-Protected, Write-Protected
z Bits 31:28 – FILTERVAL1[3:0]: Non-Recoverable Fault Input 1 Filter Value
These bits define the filter value applied on TCEx event input line. This value must be 0 when TCEx event input
line is configured as asynchronous event.
z Bits 27:24 – FILTERVAL0[3:0]: Non-Recoverable Fault Input 0 Filter Value
These bits define the filter value applied on TCEx event input line. This value must be 0 when TCEx event input
line is configured as asynchronous event.
z Bits 23:16 – INVENx [x=7..0]: Output Waveform x Inversion
These bits are used to select inversion on the output of channel x.
Writing a one to INVENx inverts output from WO[x].
Writing a zero to INVENx disables inversion of output from WO[x].
These bits define the value of the enabled override outputs, under non-recoverable fault condition.
z Bits 15:8 – NRVx [x=7..0]: Non-Recoverable State x Output Value
These bits define the value of the enabled override outputs, under non-recoverable fault condition.
z Bits 7:0 – NREx [x=7..0]: Non-Recoverable State x Output Enable
These bits enable the override of individual outputs by NRVx value, under non-recoverable fault condition.
