3.6 SMBus
The System Management Bus is a two-wire interface through which simple power-
related chips can communicate with rest of the system. It uses I2C as its backbone.
A system using SMBus passes messages to and from devices instead of tripping
individual control lines. With the SMBus, a device can provide manufacturer
information, tell the system what its model/part number is, save its state for a
suspend event, report different types of errors, accept control parameters, and return
its status.
The SMBus may share the same host device and physical bus as ACCESS bus
components provided that an appropriate electrical bridge is provided between the
interal SMB devices and external ACCESS bus devices.

individually configured to perform a simple basic I/O function. Users can configure
each individual port to become an input or output port by programming register bit
of I/O Selection. To invert port value, the setting of Inversion Register has to be
made. Port values can be set to read or write through Data Register.
