1 – Software sets ADxCON. SAMP to start sampling.

2 – Sampling starts after discharge period. TSAMP is described in Section 17. “10-bit Analog-to-Digital Converter (ADC)”

(DS61104) in the “PIC32 Family Reference Manual”.

3 – Software clears ADxCON. SAMP to start conversion.

4 – Sampling ends, conversion sequence starts.

5 – Convert bit 9.

6 – Convert bit 8.

7 – Convert bit 0.

8 – One TAD for end of conversion.
