IRQCONN
IRQSTAN Register
The IRQCONN register is the IRQ and FIQ control register. It
contains two active bits. The first to enable nesting and
prioritization of IRQ interrupts the other to enable nesting and
prioritization of FIQ interrupts.
If these bits are cleared, then FIQs and IRQs can still be used,
but it is not possible to nest IRQs or FIQs. Neither is it possible

FIQ does have a higher priority than an IRQ.

If IRQCONN.0 is asserted and IRQVEC is read, then one of
these bits is asserted. The bit that asserts depends on the

Priority 1 then Bit 1 asserts, and so forth. When a bit is set in
this register, all interrupts of that priority and lower are blocked.
