Bit 31 – ACCRO Accumulator Roll-Over Enable bit
| Value | Description |
|---|---|
| 1 | ADnDATAx accumulator is not cleared; it is allowed to roll-over. |
| 0 | ADnDATAx accumulator is cleared at the end of a multi-sample sequence. |
Bit 30 – ACCBRST Oversampling Burst Mode Enable bit
| Value | Description |
|---|---|
| 1 | The oversampling is performed as a continuous non-interruptible burst, during which all other conversion requests will be blocked out until the process is completed. |
| 0 | Oversampling can be interrupted by a high priority conversion request. |
Bit 29 – CMPVAL Comparison Value Selection bit
| Value | Description |
|---|---|
| 1 | The channel data value in the ADnDATAx register is used for comparison. |
| 0 | The immediate conversion value in ADnRESx is used for comparison. |
Bits 29:28 – CMPMODE[1:0] Comparison Mode Selection bit
| Value | Description |
|---|---|
| 1 | Accumulative violation is the basis for the violation count per ADCMPCNT[9:0] bits. |
| 0 | Consecutive violation is the basis for the violation count per ADCMPCNT[9:0] bits. |
Bits 25:16 – ADCMPSTAT[9:0] Comparison Violation Count Status bits
The corresponding CMPxRDY bit is set when the count reaches the value set in ADCMPCNT[9:0].
Bits 14:12 – CRITERIA[2:0] Comparison Criteria Selection bits
| Value | Description |
|---|---|
| 111-101 | Comparison is disabled. |
| 100 | Conversion result is less than or equal to (≤) the ADnCMPLOx register. |
| 011 | |
| 010 | Conversion result is within bounds of (≥) ADnCMPLOx and (<=) ADnCMPHIx. |
| 001 | Conversion result is out of bounds of (<) ADnCMPLOx or (>) ADnCMPHIx. |
| 000 | Comparison is disabled. |
Bits 9:0 – ADCMPCNT[9:0] Comparison Count bits
| Value | Description |
|---|---|
| 1111111111 | 1023 comparisons matching the criteria are selected. |
| 1111111110 | 1022 comparisons matching the criteria are selected. |
| ... | |
| 0000000011 | 3 comparisons matching the criteria are selected. |
| 0000000010 | 2 comparisons matching the criteria are selected. |
| 0000000001 | 1 comparison matching the criteria is selected. |
| 0000000000 | 1 comparison matching the criteria is selected. |
