1 â Software sets ADxCON. SAMP to start sampling.
2 â Sampling starts after discharge period. TSAMP is described in Section 17. â10-bit Analog-to-Digital Converter (ADC)â
(DS61104) of the âPIC32 Family Reference Manualâ.
3 â Software clears ADxCON. SAMP to start conversion.
4 â Sampling ends, conversion sequence starts.
5 â Convert bit 9.
6 â Convert bit 8.
7 â Convert bit 0.
8 â One TAD for end of conversion.
