DS70139F-page 63 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.
