AIC Interrupt Vector Register
Register Name: AIC_IVR
Access Type:
Reset Value:
Offset:
• IRQV: Interrupt Vector Register
The IRQ Vector Register contains the vector programmed by the user in the Source Vector Register corresponding to the
current interrupt.
The Source Vector Register (1 to 31) is indexed using the current interrupt number when the Interrupt Vector Register is
read.
When there is no current interrupt, the IRQ Vector Register reads 0.
AIC FIQ Vector Register
Register Name: AIC_FVR
Access Type:
Reset Value:
Offset:
• FIQV: FIQ Vector Register
The FIQ Vector Register contains the vector programmed by the user in the Source Vector Register 0 which corresponds to
FIQ.
