23.8.3
Register Name:
Access Type:
Reset Value:
• VECTOR: Source Vector
The user may store in these registers the addresses of the corresponding handler for each interrupt source.
23.8.4
Register Name:
Access Type:
Reset Value:
• IRQV: Interrupt Vector Register
The Interrupt Vector Register contains the vector programmed by the user in the Source Vector Register corresponding to
the current interrupt.
The Source Vector Register is indexed using the current interrupt number when the Interrupt Vector Register is read.
When there is no current interrupt, the Interrupt Vector Register reads the value stored in AIC_SPU.
