Bradcast packets has no target address on the AVC LAN level but I am not sure if it has no "logical" address. So, it looks like a broadcast for AVC LAN still have target address (or class) inside the data:
| Data[0] | Data[1] | Data [2] | Data[3] ... |
|---|---|---|---|
| Src addr | Target addr (or class) | Command | Data |
| example: | |||
| E4 | 31 | B6 | XX XX XX |
ECM (0x1C6[0xE4]) -> Broadcast
| Class (Target) | Command | Data | Value |
|---|---|---|---|
| 31 | B6 | XX XX XX | Driving shift position. Bitfield. [Byte:Bit] |
| [0:7] - "P" | |||
