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 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 the Pin Diagrams for CN pin locations.

Note 1:
Refer to “dsPIC30F Family Reference Manual” (DS70046) for descriptions of register bit fields. Not all peripherals, and therefore their bit
positions, are available on this device.
