1 ^{– Software sets ADx1CON1. SAMP to start sampling.}
2 – Sampling starts after discharge period. TSAMP is described in
Section 16. “Analog-to-Digital Converter (ADC)” (DS70621) of the
“dsPIC33E/PIC24E Family Reference Manual”.
3 ^{– Software clears ADxCON1. 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.
