DSP56002 signals are organized into twelve functional groups, as summarized in
Table 1-1 .
Figure 1-1 is a diagram of DSP56002 signals by functional group.
CCX
Port A signals define the External Memory Interface port.
Port B signals are the HI signals multiplexed on the external pins with the GPIO signals.
Port C signals are the SCI and SSI signals multiplexed on the external pins with the GPIO signals.
