When the link is down, the Root Complex may request reset of the End Point. This request is terminated as a PCIE_HOT_RESET_PULSE interrupt to the End Point host software. All outstanding transactions are completed in error on target port and further transactions are not generated on the controller port. Once the transactions are completely stopped, the software should issue a local reset to PCIe subsystem. The re-initialization process may then be started.
The PCIE_HOT_RESET_PULSE interrupt is generated from the HOT_RESET_OUT output of the PCIe core.
