Processor 0. Indicates that processor 0 handles any interrupt. P0 is meaningful only in a multi-core device. In a
single-core device, all interrupts that are serviced internally are directed to processor 0. Permanently set and read

Internal Interrupt Vector/Priority Registers (IIVPR0–IIVPR47)
Because all internal interrupts are active-high, clearing any IIVPRn polarity
field disables that interrupt. Care should be taken to ensure this field is not
inadvertently corrupted when loading or reloading IIVPRs with priority,
mask, or vector data.

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