Note
Selecting more than one ADHWTSn prior to a conversion
completion will result in unknown results. To avoid this,
select only one ADHWTSn prior to a conversion
completion.
• Following the transfer of the result to the data registers when continuous conversion
is enabled, that is, when ADCO=1.
If continuous conversions are enabled, a new conversion is automatically initiated after
the completion of the current conversion, by:. In software triggered operation, that is,
when ADTRG=0, continuous conversions begin after SC1A is written and continue until
aborted. In hardware triggered operation, that is, when ADTRG=1 and one ADHWTSn
event has occurred, continuous conversions begin after a hardware trigger event and
continue until aborted.
If hardware averaging is enabled, a new conversion is automatically initiated after the
completion of the current conversion until the correct number of conversions are
completed. In software triggered operation, conversions begin after SC1A is written. In
hardware triggered operation, conversions begin after a hardware trigger. If continuous
conversions are also enabled, a new set of conversions to be averaged are initiated
following the last of the selected number of conversions.
28.4.4.2 Completing conversions
A conversion is completed when the result of the conversion is transferred into the data
result registers, Rn. If the compare functions are disabled, this is indicated by setting of
SC1n[COCO]. If hardware averaging is enabled, the respective SC1n[COCO] sets only if
the last of the selected number of conversions is completed. If the compare function is
enabled, the respective SC1n[COCO] sets and conversion result data is transferred only if
the compare condition is true. If both hardware averaging and compare functions are
enabled, then the respective SC1n[COCO] sets only if the last of the selected number of
conversions is completed and the compare condition is true. An interrupt is generated if
the respective SC1n[AIEN] is high at the time that the respective SC1n[COCO] is set.
28.4.4.3 Aborting conversions
Any conversion in progress is aborted when:
