The IT8208M incorporates an extended PCI arbiter to support more PCI master bus request.
The extended PCI arbiter utilizes one set of SYSGNT# and SYSREQ# to support 3 PCI Masters, so that two more PCI Masters can be supported for the system. PCISTOP# input signal is useful to facilitate the fairness arbitration.

An Extended PCI Arbiter refers to a component or circuitry used in computer systems to manage and arbitrate access to the PCI (Peripheral Component Interconnect) bus in an extended or expanded configuration. The PCI bus is a standardized high-speed interface that allows various hardware components, such as graphics cards, network adapters, and storage controllers, to communicate with the computer’s CPU and memory.
