Well, for example, in slot IELSR05 I write Event number from table 13.4, say, corresponding to the interrupt request from VBATT_LVD. Then I attach the interrupt like this: attachInterrupt(3, VBAT_Interrupt, FALLING);
You're doing this wrong. This is an old hack that we were using to get around the fact that IRQManager.h didn't support some interrupts. There is now a attachGenericInterrupt function that you can use directly to attach your interrupt.
See here:
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"
