Signals/Connections

The DSP56303 input and output signals are organized into functional groups as shown in Table 1-1. Figure 1-1
diagrams the DSP56303 signals by functional group. The remainder of this chapter describes the signal pins in
each functional group.
Note:
This chapter refers to a number of configuration registers used to select individual multiplexed signal
functionality. Refer to the DSP56303 User’s Manual for details on these configuration registers.

Notes:
1.
Port A signals define the external memory interface port, including the external address bus, data bus, and control signals.
2.
Port B signals are the HI08 port signals multiplexed with the GPIO signals.
3.
Port C and D signals are the two ESSI port signals multiplexed with the GPIO signals.
4.
Port E signals are the SCI port signals multiplexed with the GPIO signals.
5.
There are 2 signal connections in the TQFP package and 7 signal connections in the MAP-BGA package that are not used.
These are designated as no connect (NC) in the package description (see Chapter 3).
