IDT 89HPES22H16 Data Sheet Processor SMBus PES22H16 SSMBCLK SSMBDAT MSMBCLK MSMBDAT (a) Unified Configuration and Management Bus Hot-Plug Interface The PES22H16 supports PCI Express Hot-Plug on each downstream port (ports 1 through 15). To reduce the number of pins required on the device, the PES22H16 utilizes an external I/O expander, such as that used on PC motherboards, connected to the SMBus master interface. Following reset and configuration, whenever the state of a Hot-Plug output needs to be modified, the PES22H16 generates an SMBus transaction to the I/O expander with the new value of all of the outputs ...
