5.8 System Management (SM) Bus
The 8-bit SMBus addresses uses the LSB (Bit 0) for the direction. Bit0 = 0 defines the write address, Bit0 = 1 defines the
read address for the device. The 8-bit addresses listed below shows the write adress for all devices. 7-bit SMBus adresses
shows the device address without Bit0.

A JIDA Bus No. like in former Modules cannot be provided because the EAPI driver
implementation enumerates the I2C busses dynamically. Please follow the initialisation
process like it is provided in the EAPI specification.
