1 â Software sets ADxCON. ADON to start AD operation.
2 â Sampling starts after discharge period.
TSAMP is described in Section 17. â10-bit Analog-to-Digital
Converter (ADC)â (DS61104).
3 â Convert bit 9.
4 â Convert bit 8.
5 â Convert bit 0.
6 â One TAD for end of conversion.
7 â Begin conversion of next channel.
8 â Sample for time specified by SAMC<4:0>.
