Start Conversion
0 Stop an ongoing conversion
1 Start a conversion immediately. This bit will be reset to STOP when the conversion is complete, unless Free-Running mode is enabled.
2 Start a conversion when a write to the INPUTCTRL register is performed
4 Start a conversion when an event is received by the ADC. This requires EVCTRL.STARTEI to be set to '1'.
