1 ^{– Software sets ADCON. SAMP to start sampling.}
2 ^{– Sampling starts after discharge period.}
TSAMP is described in Section 18. “12-bit A/D Converter” (DS70046) of the “dsPIC30F Family Reference Manual”.
3 ^{– Software clears ADCON. 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.}
