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 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 22 external
signals (CN0 through CN21) that may be selected
(enabled) for generating an interrupt request on a
change-of-state.
Please refer to the Pin Diagram on page 3 for CN pin
locations.
