Figure 18.2 shows a typical SMBus configuration. The SMBus0 interface will work at any voltage between 3.0 V and
5.0 V and different devices on the bus may operate at different voltage levels. The bi-directional SCL (serial clock)
and SDA (serial data) lines must be connected to a positive power supply voltage through a pull-up resistor or similar
circuit. Every device connected to the bus must have an open-drain or open-collector output for both the SCL and
SDA lines, so that both are pulled high when the bus is free. The maximum number of devices on the bus is limited
only by the requirement that the rise and fall times on the bus will not exceed 300 ns and 1000 ns, respectively.
