19. System Management BUS/I
The SMBus0 I/O interface is a two-wire, bi-directional serial bus. SMBus0 is compliant with the System
Management Bus Specification, version 2, and compatible with the I
interface by the system controller are byte oriented with the SMBus0 interface autonomously controlling
the serial transfer of the data. A method of extending the clock-low duration is available to accommodate
devices with different speed capabilities on the same bus.
SMBus0 may operate as a master and/or slave, and may function on a bus with multiple masters. SMBus0
provides control of SDA (serial data), SCL (serial clock) generation and synchronization, arbitration logic,
and START/STOP control and generation. SMBus0 is controlled by SFRs as described in
