2 Signal/Connection Descriptions

2.1 Signal Groupings

The input and output signals of the DSP56362 are organized into functional groups, which are listed in

Table 2-1 and illustrated in Figure 2-1.

The DSP56362 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.
