An integrated circuit. The integrated circuit comprises an interconnect communication bus and a plurality of peripheral component interconnect (PCI) multi-function endpoints (MFN-EPs) coupled to the interconnect communication bus, each PCI MFN-EP comprising a multiplexing device, a first address translation unit (ATU), and at least one PCI function circuit, each PCI function circuit comprising another ATU and a plurality of base address registers (BARs).

An Ethernet switch and a switch microcontroller or CPU are integrated onto a system-on-a-chip (SoC). The Ethernet switch remains independently operating at full speed even though the remainder of the SoC is being reset or is otherwise nonoperational. The Ethernet switch is on a separated power and clock domain from the remainder of the integrated SoC. A warm reset signal is trapped by control microcontroller (MCU) to allow the switch CPU to isolate the Ethernet switch and save state. When the Ethernet switch is isolated and operating independently, the warm reset request is provided to the other entities on the integrated SoC. When warm reset is completed, the state is restored and the various DMA and flow settings redeveloped in the integrated SoC to allow return to normal operating condition.
