• Manufacturer: Freescale Semiconductor, Inc

5.6.10.8
This field is used to set the interrupt priority level for IRQs. This IRQ is limited to priorities 0 through 2.
They are disabled by default.
5.6.11
5.6.11.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
5.6.11.2
The contents of this register determine the location of the Vector Address Table. The value in this register
is used as the upper 13 bits of the interrupt Vector Address Bus (VAB[20:0]). The lower eight bits are
determined based upon the highest-priority interrupt. They are then appended onto VBA before presenting
the full interrupt address to the 56800E core; see
5.6.12
5.6.12.1
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
