8.3 Input Change Notification Module

The input change notification module provides the

dsPIC30F devices the ability to generate interrupt

requests to the processor in response to a Change-Of-

State (COS) on selected input pins. This module is

capable of detecting input Change-Of-States, even in

Sleep mode, when the clocks are disabled. There are

10 external signals (CN0 through CN7, CN17 and

CN18) that may be selected (enabled) for generating

an interrupt request on a Change-Of-State.

Please refer to Pin Diagrams (Continued) for CN pin

locations.
