but I could not find a way to do it with the Arduino API

Use the funcions in IRQManager.h

For most interrupts like your timer and pin interrupts there are dedicated functions. There is also a function for adding interrupts by ELC code for those that aren't otherwise covered.

RA4M1 Interrupts

The new renesas-uno platform 1.2.0 has a new function for attaching generic interrupts that aren't covered elsewhere in the IRQManager.h Here's a test sketch that attaches IRQ0 using the new function. This could be done with attachInterrupt instead, but pin interrupts are easy to set up so I used this for illustration. The function will be handy for things like the CAC and CTSU that aren't implemented in the Arduino core and aren't covered in IRQManger.h #include "IRQManager.h" volatile boo…
