1 – Software sets ADxCON. SAMP to start sampling.

2 – Sampling starts after discharge period. TSAMP is described

in Section 16. “Analog-to-Digital Converter (ADC) with DMA”

(DS70183) in the “dsPIC33F/PIC24H Family Reference Manual”.

3 – Software clears ADxCON. SAMP to start conversion.

4 – Sampling ends, conversion sequence starts.
