8.2.1.1 No special format

No special format = default setting
A synchronous-serial data transmission with No special format is min. 8 bits, or
max. 36 bits long. The data transmission begins with the most significant bit (MSB)
and contains the position bits (P).
Related to a certain number of clocks, the data can be shifted arbitrarily by the
parameter Number of data bits. The data can be transmitted right-justified or
left-justified, with leading "zeros" and without leading "zeros". Leading "zeros" are
produced if the parameter Number of data bits is programmed larger, as it would
be necessary from the total measuring length.
