Signal Groupings

The input and output signals of the DSP56374 are organized into functional groups, which are listed in Table 3..

The DSP56374 is operated from a 1.25 V and 3.3 V supply; however, some of the inputs can tolerate 5.0 V. A special notice for

this feature is added to the signal descriptions of those inputs.

Note:

1. Pins are not 5 V. tolerant unless noted.

2. Port H signals are the GPIO port signals which are multiplexed with the MOD and HREQ signals.

3. Port G signals are the dedicated GPIO port signals.

4. Port C signals are the GPIO port signals which are multiplexed with the ESAI signals.

5. Port E signals are the GPIO port signals which are multiplexed with the ESAI_1 signals.
