20. SMBus Connector (3-pin SMB) (optional/reserved)

This connector allows you to connect SMBus devices. SMBus devices commu-

nicate by means of the SMBus with an SMBus host and/or other SMBus de-

vices. The SMBus or System Management Bus is a specific implementation of

an I

C bus, which is a multi-master bus, that is, multiple chips can be connected

to the same bus and each one can act as a master by initiating data transfer.
