1 – Software sets ADxCON. SAMP to start sampling.
2 ^{– Sampling starts after discharge period.}
TSAMP is described in Section 16. “10/12-bit ADC with DMA” the “dsPIC33F Family Reference Manual”.
3 – Software clears ADxCON. SAMP to start conversion.
4 ^{– Sampling ends, conversion sequence starts.}
5 – Convert bit 11.
6 – Convert bit 10.
7 – Convert bit 1.
8 ^{– Convert bit 0.}
9 ^{– One TAD for end of conversion.}
