Comparator Control Register Definition
Description
Signal Select for Positive Input
0 = GPIO pin used as positive comparator input.
1 = Temperature sensor used as positive comparator input.
Signal Select for Negative Input
0 = Internal reference disabled, GPIO pin used as negative comparator input.
1 = Internal reference enabled as negative comparator input.

The following code example illustrates how to safely enable the comparator:
di
ld cmp0, r0 ; load some new configuration
nop
nop
clr irq0 ; clear any spurious interrupts pending
ei
The Comparator Control Register (CMP0) configures the comparator inputs and sets the
value of the internal voltage reference.
