1 ^{– Software sets ADxCON. ADON to start AD operation.}
2 – Sampling starts after discharge period.
TSAMP is described in the “PIC32MX
Family Reference Manual” (DS61132).
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>.}
