- 8-bit addressing (256 unique addressess).
- Multicast, and broadcast addresses.
- Addresses are preallocated, and remain fixed.
- The adress pool is shared by all models that utilise this bus system. i.e. once the address
0x69was allocated to the E31 body module, it was not reallocated, even on models to which the device was not applicable to. - Variants of a device will have the same address, e.g. the address
0x80is used by the low cluster (KOMBI), high clusters (IKE, IKI). - All buses are within the 8-bit scope, i.e. an address is unique across the I, K, and D buses.
Only common I and K bus device addresses are listed.
