Description
Reserved
This bit is reserved and must be programmed to 0.
Signal Select for Negative Input
0 = internal reference disabled, GPIO pin used as negative comparator input.
1 = internal reference enabled as negative comparator input.
Internal Reference Voltage Level
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.
Reserved
These bits are reserved and must be programmed to 00.

The Comparator Control Register (CMP0) configures the comparator inputs and sets the
value of the internal voltage reference. The GPIO pin is always used as positive compara-
tor input.
