External interrupt
Component Level: High
Category:
CPU Internal Peripherals-Interrupts
This component implements an external interrupt. The interrupt is caused by a signal level/edge on a pin. The pin and the level/edge are specified in the Properties. In a response to the interrupt, the driver calls the OnInterrupt event.
Version specific information for HCS08 and ColdfireV1 derivatives:
Generate interrupt on property allows to select the generation of the interrupt only on either the low level or falling edge even if any of the pins have more possibilities. Invert interrupt trigger condition property can be used to enable the generation of the interrupt on the high level or rising edge.

Version specific information for ColdfireV1 derivatives:
If the external interrupt pin is not shared with GPIO functionality port GetVal method is disabled. These CPUs have no possibility to detect the actual value of the input pin.
