*
* The builtin peripherals are masked through dedicated bits in the
* Interrupt Mask register (IMR) - and this is not indexed (or in any way
* related to) the actual interrupt number they use. So knowing the IRQ
* number doesn't explicitly map to a certain internal device for
* interrupt control purposes.
