16.2.8 Edge Selectable Interrupt-on-Change

An interrupt can be generated by detecting a signal at the port pin that has either a rising edge or a falling edge. Individual pins can be independently configured to generate an interrupt. The Interrupt-on-Change module is present on all the pins that are common between 28-pin and 40/44-pin devices. For further details about the IOC module, refer to the “Interrupt-on-Change” chapter.
