Section 4: Specification of Input and
General requirement: Depending on the Master it is possible that the Lowbyte (Bit 0 - 7)
and the High byte (Bit 8 - 15) are to be switched. Generally speaking, the mode of
transmission (Big Endian / Little Endian) has to be set in a way that ensures the correct
transmission of the analogue information. Only after this has been accomplished, the binary
data can be transmitted.
