Run in Standby
This bit determines whether the ADC needs to run when the chip is in Standby Sleep mode.
Resolution Selection
This bit selects the ADC resolution.
| Value | Description |
|---|---|
| 0 | Full 10-bit resolution. The 10-bit ADC results are accumulated or stored to the ADC Result register (ADC.RES). |
| 1 | 8-bit resolution. The conversion results are truncated to eight bits (MSBs) before they are accumulated or stored to the ADC Result register (ADC.RES). The two Least Significant bits are discarded. |
Free-Running
Writing a '1' to this bit will enable the Free-Running mode for the data acquisition. The first conversion is started by writing COMMAND.STCONV bit high. In the Free-Running mode, a new conversion cycle is started immediately after or as soon as the previous conversion cycle has completed. This is signaled by INTFLAGS.RESRDY.
ADC Enable
| Value | Description |
|---|---|
| 0 | ADC is disabled |
| 1 | ADC is enabled |
