2.1.1.1
The basic structure of a read/write access to the T-SMINT
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 T-SMINT
The possible sequences are listed in
•
Table 5
Header 40
The non-interleaved A-D-A-D sequences give direct read/write access to the address
range 00
