Private Management I²C Buses
The National Semiconductor PC87431 integrated management controller implements a single
private management bus. The National Semiconductor PC87431 integrated management
controller is the sole master on this bus. External agents must use the National Semiconductor
PC87431 integrated management controller Master Write/Read I²C command if they require
direct communication with a device on this bus. In addition, the National Semiconductor
PC87431 integrated management controller provides a Reserve Device command that gives an
external agent exclusive access to a specific device for a selectable time.
5.1.5
Messaging Interfaces
This section describes the supported National Semiconductor PC87431 integrated management
controller communication interfaces:
• Host SMS interface via SMBus interface
• LAN interface using the LAN On Motherboard SMBus
