Signal/Connection Descriptions
2.1
Signal Groupings
The input and output signals of the DSP56364 are organized into functional groups, which are listed in
Table 2-1
and illustrated in
Figure 2-1
.
The DSP56364 is operated from a 3.3 V supply; however, some of the inputs can tolerate 5 V. A special
notice for this feature is added to the signal descriptions of those inputs.
