pares two analog input signals. A GPIO (
input. The negative input (
internal reference. The output is available as an interrupt source or can be routed to an
external pin using the GPIO multiplex. Features include:

One of the comparator inputs may be connected to an internal reference which is a user
selectable reference that is user programmable with 200 mV resolution.
The comparator may be powered down to save on supply current. See the

Because of the propagation delay of the comparator, it is not recommended to enable the
comparator without first disabling interrupts and waiting for the comparator output to
settle. Doing so can result in spurious interrupts after comparator enabling. The follow-
ing example shows how to safely enable the comparator:
2 inputs which can be connected up using the GPIO multiplex (MUX)
1 input can be connected to a programmable internal reference
1 input can be connected to the on-chip temperature sensor
Output can be either an interrupt source or an output to an external pin
