1
– Software sets ADxCON. SAMP to start sampling.
2
– Sampling starts after discharge period. T
SAMP is described in Section 16. “Analog-to-Digital Converter (ADC)”
3
– Software clears ADxCON. SAMP to start conversion.
4
– Sampling ends, conversion sequence starts.
5
– Convert bit 9.
8
– One TAD for end of conversion.
