DS80PCI810EVM Configuration Overview
The following tables describe the various connectors and user-controllable settings available on the
DS80PCI810EVM. Since the device can operate in one of three modes (pin mode, SMBus slave mode,
and SMBus master mode), note the switch description that matches the intended mode of operation. For
more information about specific EQ, VOD, and SD_TH values, see the DS80PCI810 datasheet.
