If the PHY link is disconnected, the PCIE_LINK_STATE_PULSE interrupt will be generated. The expected course of action is to reset the entire PCIe subsystem and restart. All application states must also be initialized so that the operations can resume following the reset and renegotiation of the link.
The PCIE_LINK_STATE_PULSE interrupt is generated from the LINK_DOWN_RESET_OUT output of the PCIe core.
