is there a way to have a simple Interrupt on a port pin ( rising / falling edge ) ?

... or do I have to use a CCU ?

Hi Volker,

You can use ERU to send trigger "messages" from port to other on-chip resources. Details can be found in "xmc4500_rm_v1+2_2012_12_" Chapter 4.5.
You can IO, ERU & NVIC Apps to build this application.

Best regards,
Sophia

Hi,

You might wish to download the project example: External Intr ERU001_ERU002_Example2
ERU001 App and ERU002 App are used to provide an external interrupt. The external interrupt event is created by port pin toggling .
