IRQCONN Register
The IRQCONN register is the IRQ and FIQ control register. It
contains two active bits. The first to enable nesting and prioritiza-
tion 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, nor is it possible to
set an interrupt source priority level. In this default state, an
FIQ does have a higher priority than an IRQ.

Description

Reserved
These bits are reserved and should not be
written to.
1
ENFIQN
Setting this bit to 1 enables nesting of FIQ
interrupts. Clearing this bit means no nesting
or prioritization of FIQs is allowed.
0
ENIRQN
Setting this bit to 1 enables nesting of IRQ
interrupts. Clearing this bit means no nesting
or prioritization of IRQs is allowed.
IRQSTAN Register
If IRQCONN.0 is asserted and IRQVEC is read then one of
these bits is asserted. The bit that asserts depends on the
priority of the IRQ. If the IRQ is of Priority 0 then Bit 0 asserts,
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.
To clear a bit in this register, all bits of a higher priority must be
cleared first. It is only possible to clear one bit at a time. For
example, if this register is set to 0x09 then writing 0xFF changes
the register to 0x08, and writing 0xFF a second time changes
the register to 0x00.
