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” in the dsPIC30F Family Reference Manual (DS70046).
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.}
