A/D operating modes
Fixed channel, single conversion mode:
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.
Fixed channel, continuous conversion mode:
A single input channel can be
selected for continuous conversion. The results of the conversions will be sequentially
placed in the four result registers. An interrupt, if enabled, will be generated after
every four conversions. Additional conversion results will again cycle through the four
result registers, overwriting the previous results. Continuous conversions continue
until terminated by the user.
Auto scan, single conversion mode:
Any combination of the four 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 which corresponds to the
selected input channel. An interrupt, if enabled, will be generated after all selected
channels have been converted. If only a single channel is selected this is equivalent
to single channel, single conversion mode.
Auto scan, continuous conversion mode:
Any combination of the four input
channels can be selected for conversion. A conversion of each selected input 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 all selected
