In Accumulate mode (
MD
=
‘b001), after
every conversion, the ADC result is added to the
ADACC
register. The ADACC register is right-shifted by the value of the
CRS bits. This right-shifted value is copied into the
ADFLTR
register. The Formatting mode does not affect the right-justification of the ADACC or
ADFLTR values. Upon each sample,
ADCNT is incremented, counting the number of samples
accumulated. After each sample and accumulation, the ADFLTR value has a threshold
comparison performed on it (see the
Threshold Comparison section) and the ADCHxIF interrupt may trigger.
