1 – Software sets ADxCON. SAMP to start sampling.
2 – Sampling starts after discharge period. T
SAMP
is described in Section 17. “10-bit 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 T
AD
for end of conversion.
