Comparator Inputs. Two analog comparators are added to input of Port 3, P31,
and P32, for interface flexibility. The comparators reference voltage P33 (REF) is
common to both comparators.
Typical applications for the on-board comparators; Zero crossing detection, AID
conversion, voltage scaling, and threshold detection. In Analog Mode, P33 input
functions serve as a reference voltage to the comparators.
The dual comparator (common inverting terminal) features a single power supply
which discontinues power in STOP Mode. The common voltage range is 0-4 V
when the V
dB and 60 dB, respectively.
Interrupts are generated on either edge of Comparator 2’s output, or on the falling
edge of Comparator 1’s output. The comparator output is used for interrupt gener-
