dsPIC30F2011/2012/3012/3013

7.3 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 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 up to 10

external signals (CN0 through CN7, CN17 and CN18)

that may be selected (enabled) for generating an

interrupt request on a change of state.
