System-on-Chip
Vectored Interrupt Controller (VIC)
VIC, where hardware determines the interrupt priority
(see Table 11). The VIC is also where the appropriate
signal to the processor (IRQ or FIQ) is generated. The
processor services the interrupt as either a vectored
interrupt or a default-vectored interrupt.

• Twenty-three internal
• Two used as software interrupts.
and cleared individually, and individual status can be
determined. On reset, all interrupts are disabled.
Preliminary data sheet
All internal and external interrupts are routed to the
The VIC accepts inputs from 32 interrupt source lines:
All 32 interrupt source lines can be enabled, disabled,
