XGATE Interrupt Priority Level — The XILVL[2:0] bits configure the shared interrupt level of the XGATE
interrupts coming from the XGATE module. Out of reset the priority is set to the lowest active level (“1”).

Interrupt Vector Base Address Bits — These bits represent the upper byte of all vector addresses. Out of
reset these bits are set to 0xFF (i.e., vectors are located at 0xFF10–0xFFFE) to ensure compatibility to
previous S12 microcontrollers.
Note: A system reset will initialize the interrupt vector base register with “0xFF” before it is used to determine

the reset vector address. Therefore, changing the IVBR has no effect on the location of the three reset
vectors (0xFFFA–0xFFFE).
IVBR are ignored and the upper byte of the vector address is fixed as “0xFF”.
