Product data sheet
9.4.1 Fixed channel, single conversion mode
9.3 Block diagram
9.4 A/D operating modes
A single input channel can be selected for conversion. A single conversion will be
performed and the result placed in the result register which corresponds to the selected
input channel. An interrupt, if enabled, will be generated after the conversion completes.
