Pin Interrupts

Pin interrupts are input from pins TINT121 to TINT0. Signals input on pins TINT121 to TINT0 are conveyed as

interrupt signals regardless of mode settings and pin function settings for the general-purpose I/O port pin.

Accordingly, if pin interrupts are to be used in port mode, set the pin as an input port pin. Alternatively, if an alternative

mode is selected, the alternative pin with an input function can only be used for pin interrupts. For the settings of general-

purpose I/O port pins, see section 41., Ports.

For the pin interrupts, high-level or rising-edge detection can be selected individually for each pin by the interrupt

configuration registers (ICDICFRn). For a description of the interrupt configuration registers (ICDICFRn), see the GIC

architecture specification.
