If the transfer type is set to 1, the reply consists only of 1 telegram ("expedited transfer"), i.e. the
amount of transferred data is 0..4 bytes.
If the size indicator is set to 1, and the expedited bit is set, the length field contains the amount of
data, that must be ignored, i.e., if the length is marked with "2", only the last 2 bytes (6 & 7) of the 8
byte telegram contain relevant data, the other 2 (4 & 5) may contain any (useless) data. Data is left
aligned.
