If you are not using the priority level in the VIC, write the VICxVectAddr
register with any value (in order to disable the interrupt priority) at the
beginning of your program.
It is not always clear when the ARM debuggers read the VICxVectAddr
register, so it is recommended that if you are using a debugger, do not read
the VIC registers via a memory window. If you must read the VIC registers,
read only the VIC registers that are needed.
VectorAddr:
VIC1DefVectAddr: 0x800B_0034 - Read/Write
VIC2DefVectAddr: 0x800C_0034 - Read/Write
Default Vector Address Register. The VICxDefVectAddr register contains the
default ISR address.
DefaultVectorAddr: Contains the address of the default ISR handler.

Contains the address of the currently active ISR. Any
writes to this register clear the interrupt.
