The core has 4 additional 32-bit registers `q0 .. q3` that are used for IRQ
handling. When an IRQ triggers, the register `q0` contains the return address
and `q1` contains a bitmask of all active IRQs. I.e. one call to the interrupt
and `q1` contains a bitmask of all active IRQs. This means one call to the interrupt
handler might need to service one than more IRQ when more than one bit is set
in `q1`.
