EEC - Emergency Error Codes following ETG specifications:
0xFFxx: Vendor-specific emergency message (VIPA = 0xFF00)
0xA0xx: State Machine transition error, e.g. due to a configuration error (length,
address, settings). More information concerning this may be found at ETG.

- Error register - State of the State Machine:
01: Init
02: Pre-Op
03: BootStrap
04: Safe-Op
08: Op
DATA - Error data with more information concerning the error
With a hardware interrupt or diagnostic interrupt respectively in DATA the Manufacturer
