Bit | Field | Type | Reset | Description |
---|---|---|---|---|
31-24 | CNT_THRESH | R/W | 0000 0000 | Sets the number of received comparator events before declaring a fault |
23-19 | Reserved | R | 0000 0 | |
18 | COMP_POL | R/W | 0 | Digital Comparator 0 Polarity 0 = Digital Comparator result asserted if value below threshold (Default) 1 = Digital Comparator result asserted if value above threshold |
17-15 | FE_SEL | R/W | 000 | Selects which Front End absolute data is used for Digital Comparison with threshold 0 = Front End 0 absolute data selected (Default) 1 = Front End 1 absolute data selected 2 = Front End 2 absolute data selected 3 = Front End 0 error data selected 4 = Front End 1 error data selected 5 = Front End 2 error data selected |
14 | CNT_CLR | R/W | 0 | Comparator Detection Counter clear 0 = No clear of Comparator Detection Counter (Default) 1 = Clear Comparator Detection counter and associated fault |
13 | CNT_CONFIG | R/W | 0 | Comparator Detection Counter configuration 0 = Counter clears upon receipt of sample which does not exceed comparator threshold (Default) 1 = Counter decrements by 1 upon receipt of sample which does not exceed comparator threshold |
12 | INT_EN | R/W | 0 | Comparator Interrupt Enable 0 = Disables Comparator Interrupt generation (Default) 1 = Enables Comparator Interrupt generation |
11 | COMP_EN | R/W | 0 | Digital Comparator 0 Enable 0 = Disables Digital Comparator 0 (Default) 1 = Enables Digital Comparator 0 |
10-0 | THRESH | R/W | 000 0000 0000 | Sets the digital comparator threshold, 11-bit signed value with resolution of 1.5625mV/bit |
