- These bits are ignored if CTRLB.SWCNVEN = 1.
- These bits are Enabled Protected (Writes are ignored when CTRLA.ENABLE = 1 returns a bus error).
- These bits not available in 64-pin package.
| Value | Description |
|---|---|
| 0 | Rising edge scan trigger mode select. A rising edge trigger event will initiate a single but complete scan of all included scan channels defined in CHNCFG21.CSSy (default). |
| 1 | Level scan trigger mode select. As long as the trigger event stays a logic high when The corresponding CHNCFG40/ CHNCFG50 TRGSRCx = 0b0011, (SCANTRG - Scan Trigger Select), the entire scan will re-trigger continuously. |

- In addition to setting the CHNCMPENn bit in this register, the associated ADC Digital Comparator must be also properly configured in its Digital Comparator Control Register, CMPCTRL0 as well as EVCTRL0.CMPEO.
- These bits are ignored if CTRLB.SWCNVEN = 1 and are Enabled Protected (Writes are ignored when CTRLA.ENABLE = 1. Returns a bus error.)
- These bits not available in 64-pin package.
| Value | Description |
|---|---|
| 0 | ADC analog channel is not monitored by ADC internal digital comparator |
| 1 | ADC analog channel conversion result is monitored by ADC internal digital comparator |
