The next steps are to clear the interrupt flag in the interrupt handler, to call the specific function for the identified
interrupt source and to clear the interrupt in the stat register. This code can be found in the file IRQSave0_xx.s.
Finally, the context and the PC have to be restored. This code can be found in the IRQComon_xx.s file.
