(15). System Management Bus Headers

This header is reserved for system management bus (SM bus). The SM bus is a specific implementation
2 2
of an I C bus. I C is a multi-master bus, which means that multiple chips can be connected to the same
bus and each one can act as a master by initiating a data transfer. If more than one master simultaneously
tries to control the bus, an arbitration procedure decides which master gets priority.
