Documentation

Table 2 lists the documents that provide a complete description of the DSP56374 and are required to design properly with the

part. Documentation is available from a local Freescale Semiconductor, Inc. (formerly Motorola) distributor, semiconductor sales

office, Literature Distribution Center, or through the Freescale DSP home page on the Internet (the source for the latest

information).

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.

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.
