3.2.1.1
The basic structure of a read/write access to the IPAC-X registers via the serial control
interface is shown in
Figure 9
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 IPAC-X.
The possible sequences for access to the complete address range 00
