31.4.3 Accumulate Mode
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.
