1 – Software sets AD1CON. SAMP to start sampling.
2 ^{– Sampling starts after discharge period. TSAMP is described in}
Section 16. “Analog-to-Digital Converter” (DS70183) in the
“dsPIC33F/PIC24H Family Reference Manual”.
3 – Software clears AD1CON. SAMP to start conversion.
4 ^{– Sampling ends, conversion sequence starts.}

5 ^{– Convert bit 11.}
6 ^{– Convert bit 10.}
7 ^{– Convert bit 1.}
8 ^{– Convert bit 0.}
9 ^{– One TAD for end of conversion.}
