PIB Interrupt Mask Register
The PIB_INTR and PIB_INTR_MASK registers control the interrupt behavior of the P-Port to the FX3 CPU. PIB_INTR indi-
cates interrupt cause, and PIB_INTR_MASK masks the causes that may assert INTR. These interrupts represent the P-Port
specific interrupts. The DMA adapter for P-Port has a number of socket-related interrupt causes that are outlined in the FX3
DMA Subsystem chapter on page 58.
