1 ^{– Software sets ADxCON. SAMP to start sampling.}
2 ^{– Sampling starts after discharge period. TSAMP is described in Section 17. “10-bit Analog-to-Digital Converter (ADC)”}
(DS61104) in the “PIC32 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.}
