1 – Software sets ADxCON. SAMP to start sampling.
2 – Sampling starts after discharge period. TSAMP is described in Section 16. “10/12-bit ADC with DMA” in the “dsPIC33F
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.
