Data Sheet
2.1.1.1
The principle structure of a read/write access to the SCOUT-DX registers via the serial
control interface is shown in figure 8.
Figure 8
Serial Command Structure
A new programming sequence starts with the transfer of a header byte. The header byte
specifies different programming sequences allowing a flexible and optimized access to
the individual functional blocks of the SCOUT-DX.
The possible sequences are listed in table 3 and are described afterwards.
