SIGNAL/CONNECTION DESCRIPTIONS

SIGNAL GROUPINGS

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

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

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.

Port A is the external memory interface port, including the external address bus, data bus, and

control signals.

Port B signals are the GPIO port signals which are multiplexed with the HDI08 signals.

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

Port D signals are the GPIO port signals which are multiplexed with the DAX signals.
