Memory-Mapped I/O and Software Interface
The Memory-Mapped I/O (MMIO) register descriptions for each of the four PCI
functions of the integrated GbE controller are not in this document. The MMIO register
descriptions are in the Intel
®
Atom™ Processor C2000 Product Family Integrated GbE
Controller Programmer’s Reference Manual (PRM). The PRM also provides details for
each function’s IOADDR and IODATA registers located in I/O space that can be used to
access the controller’s internal registers and memory units.

System Manageability
Network management is an important requirement in today's networked computer
environment. Software-based management applications provide the ability to
administer systems while the operating system is functioning in a normal power state,
that is, when not in a pre-boot state or powered-down state. The System Management
Bus (SMBus) Interface, Management Component Transport Protocol (MCTP) and the
Network Controller Sideband Interface (NC-SI) fill the management void that exists
when the operating system is not running or fully functional. This is accomplished by
providing mechanisms by which manageability network traffic can be routed to and
from a Management Controller (MC) such as a Baseboard Management Controller
(BMC).
The Intel
®
Atom™ Processor C2000 Product Family Integrated GbE Controller
Programmer’s Reference Manual (PRM) describes the supported management
interfaces and supported hardware configurations for platform system management. It
describes the interfaces to an external BMC, the partitioning of platform manageability
among system components, and the functionality provided by in each platform
configuration. For an overview of the hardware interface, see
The SoC integrated GbE controller has the ability to route Ethernet traffic to the host
operating system as well as the ability to send Ethernet traffic over the sideband
interface to an external BMC. The term “Pass-Through” (PT) is used when referring to
the process of the LAN Port sending and receiving Ethernet traffic over the sideband
(SMBus or NC-SI) interface to/from the BMC. See
