23.8.5
Register Name:
Access Type:
Reset Value:
• FIQV: FIQ Vector Register
The FIQ Vector Register contains the vector programmed by the user in the Source Vector Register 0. When there is no
fast interrupt, the FIQ Vector Register reads the value stored in AIC_SPU.
23.8.6
Register Name:
Access Type:
Reset Value:
• IRQID: Current Interrupt Identifier
The Interrupt Status Register returns the current interrupt source number.
