0: Single conversion mode
1: Continuous conversion mode
This bit is set and cleared by software. If this bit holds a value of zero and a 1 is written to it
then it wakes up the ADC from Power Down state.
Conversion starts when this bit holds a value of 1 and a 1 is written to it. The application

These bits are written by software to select the sample time individually for each channel.
During sample cycles channel selection bits must remain unchanged.
