The VICxRawIntr register provides the status of the source interrupts (and
software interrupts) to the interrupt controller.
RawIntr:
VIC1IntSelect: 0x800B_000C - Read/Write
VIC2IntSelect: 0x800C_000C - Read/Write
Interrupt Select Register. The VICxIntSelect register selects whether the
corresponding interrupt source generates an FIQ or an IRQ interrupt.
IntSelect:
VIC1IntEnable: 0x800B_0010 - Read/Write
VIC2IntEnable: 0x800C_0010 - Read/Write
