SPC58 - Finding the IRQ number when handling IVOR04

FCasa.9

Hello ST Community,

Does anyone know which register I can read to find which IRQ triggered an IVOR04 exception, on SPC58?

I am using the software vector mode, and the interrupt controller (INTC_IACKR) only gives me the address of the ISR... which is unfortunate when the IRQ is mapped to a generic ISR.

Thanks.
