10.6.2 PIB_INTR
PIB Interrupt Request 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.
31 GPIF_ERR An error occurred in the GPIF. Firmware clears this bit after handling the error. The error code is indi-
cated in PIB_ERROR.GPIF_ERR_CODE.
29 PIB_ERR The socket-based link controller encountered an error and needs attention. Firmware clears this bit
after handling the error. The error code is indicated in PIB_ERROR.PIB_ERR_CODE.
10 RD_THRESHOLD Indicates that AP has written to PP_RD_THRESHOLD register.
9 WR_THRESHOLD Indicates that AP has written to PP_WR_THRESHOLD register.
8 CONFIG_CHANGE AP has written a new value into PP_CONFIG.
7CLOCK_LOST PIB_CLK is no longer present. See PIB_CLOCK_DETECT for more details.
