1 – Software sets ADxCON. SAMP to start sampling.
2 ^{– Sampling starts after discharge period. TSAMP is described in Section 46. “10-bit Analog-to-Digital Converter (ADC)}
with 4 Simultaneous Conversions” (DS39737) in the “PIC24F 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.}
