Bit 0: fixed at 0
Bit 1: slave not ready for data transfer
Bit 2: configuration data is not identical
Bit 3: slave got extern diagnostic data
Bit 4: slave does not provide this function
Bit 5: fixed at 0
Bit 6: wrong parameterization
Bit 7: fixed at 0
1

Bit 2: fixed at 1
Bit 3: response control active
Bit 4: freeze command received
Bit 5: sync command received
Bit 6: reserved
Bit 7: fixed at 0
2
Bit 0...Bit 6: reserved
Bit 7: Diagnostic data overflow
3
