1 – Software sets ADxCON. ADON to start AD operation.

2 – Sampling starts after discharge period. TSAMP is described

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

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

3 – Convert bit 9.

4 – Convert bit 8.

5 – Convert bit 0.

6 – One TAD for end of conversion.

7 – Begin conversion of next channel.

8 – Sample for time specified by SAMC<4:0>.
