MOTOROLA
If the core initiates an interrupt acknowledge cycle prior to the PIVR being programmed,
the interrupt controller returns the uninitialized interrupt vector (0x0F). If the core initiates
an interrupt acknowledge cycle after the PIVR has been initialized, but there is no interrupt
pending, the interrupt controller returns the user a spurious interrupt vector (0xxxx0_0000).
Because the interrupt controller responds to all interrupt acknowledges, a bus error situation
cannot occur during an interrupt-acknowledge cycle.
Table 7-7 describes PIVR fields.
Table 7-8 lists the values for the five least significant bits of the interrupt vector. The vector
numbers shown assume PIVR[IV]=0b010. If another value of PIVR[IV] is used, the vector
numbers would change accordingly.

These bits provide the high three bits of the interrupt vector for interrupt acknowledge cycles from all
sources. To conform to the core interrupt vector allocation, these bits should be set equal to or greater
than 010. See Table 2-3.
