1 – Software sets AD1CON. SAMP to start sampling.

2 – Sampling starts after discharge period. TSAMP is described in

Section 28. “10/12-bit ADC without DMA” (DS70210) in the

“dsPIC33F/PIC24H Family Reference Manual”.

3 – Software clears AD1CON. 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.
