A single input channel can be selected for conversion. A single conversion will be
performed and the result placed in the result register pair which corresponds to the
selected input channel. An interrupt, if enabled, will be generated after the conversion
completes.
A single input channel can be selected for continuous conversion. The results of the
conversions will be sequentially placed in the eight result register. The user may select
whether an interrupt can be generated after every four or every eight conversions.
Additional conversion results will again cycle through the result register pairs, overwriting
the previous results. Continuous conversions continue until terminated by the user.
Any combination of the eight input channels can be selected for conversion. A single
conversion of each selected input will be performed and the result placed in the result
register pair which corresponds to the selected input channel. The user may select
whether an interrupt, if enabled, will be generated after either the first four conversions
have occurred or all selected channels have been converted. If the user selects to
generate an interrupt after the four input channels have been converted, a second
interrupt will be generated after the remaining input channels have been converted. If only
a single channel is selected this is equivalent to single channel, single conversion mode.
