2.1.1.1
The basic structure of a read/write access to the Q-SMINT I registers via the serial
control interface is shown in
•
Figure 7
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 Q-SMINT I.
The possible sequences are listed in
