The Comparator Control Register (CMPCTL) configures the comparator inputs and sets
the value of the internal voltage reference.
INPSEL—Signal Select for Positive Input
0 = GPIO pin used as positive comparator input
1 = temperature sensor used as positive comparator input
INNSEL—Signal Select for Negative Input
0 = internal reference disabled, GPIO pin used as negative comparator input
1 = internal reference enabled as negative comparator input
REFLVL—Internal Reference Voltage Level (note that this reference is independent of the
ADC voltage reference)
0000 = 0.0 V
0001 = 0.2 V
0010 = 0.4 V
0011 = 0.6 V
0100 = 0.8 V
0101 = 1.0 V (Default)
0110 = 1.2 V
0111 = 1.4 V
1000 = 1.6 V
1001 = 1.8 V
1010–1111 = Reserved
