10.3.1.7
The interprocessor interrupt (IPI) vector/priority registers contain the interrupt vector and priority fields
for the four interprocessor interrupt channels as shown in
register per channel. The VECTOR and PRIORITY values should not be changed while IPIVPRn[A] is
set.

12–15 PRIORITY Priority. Specifies the interrupt priority. The lowest priority is 0 and the highest priority is 15. A priority level of
16–31 VECTOR Vector. The vector value in this field is returned when the interrupt acknowledge (IACK) register is read and

Mask. Mask interrupts from this source. Always set following reset.
0 An interrupt request is generated if the corresponding IPR bit is set.
1 Further interrupts from this source are disabled.
Activity. Indicates an interrupt has been reported or is in-service. Note that this field is read only. The values
of VECTOR and PRIORITY should not be changed while IPIVPR n [A] is set.
0 No current interrupt activity associated with this source.
1 The interrupt bit for this source in the IPR or ISR is set.
