1 – Software sets ADxCON. ADON to start AD operation.

2 – Sampling starts after discharge period.

TSAMP is described in Section 17. “10-bit Analog-to-Digital

Converter (ADC)” (DS61104).

3 – Convert bit 9.

4 – Convert bit 8.

5 – Convert bit 0.

6 – One TAD for end of conversion.

7 – Begin conversion of next channel.

8 – Sample for time specified by SAMC<4:0>.
