The interrupt function may either be combined with the pin’s main function or may be used instead of it, i.e. if the main pin function is not required. Interrupt signals may be connected to: • EX7IN...EX0IN, the fast external interrupt input pins, • T4IN, T2IN, the timer input pins • CAPIN, the capture input of GPT2 For each of these pins either a positive, a negative, or both a positive and a negative external transition can be selected to cause an interrupt or PEC service request. The edge selection is performed in the control register of the peripheral device associated with the respective port pin. The peripheral must be programmed to a specific operating mode to allow generation of an interrupt by the external signal. The priority of the interrupt request is determined by the interrupt control register of the respective peripheral interrupt source, and the interrupt vector of this source will be used to service the external interrupt request. Note: In order to use any of the listed pins as external interrupt input, it must be switched to input mode via its direction control bit DPx.y in the respective port direction control register DPx.
