Description
The System Management Bus (SMBus) is a two-wire interface through which simple system and power management related chips can communicate with the rest of a system. SMBus provides a control bus for system and power management related tasks. The SMBus is a multi-master bus, meaning that more than one device capable of controlling the bus can be connected to it. This core is based on the SMBus 2.0 specification, and utilizes its address resolution protocol using an 128-bit unique device identifier (UDID).
