7 / 156 page ![]() MOTOROLA DSP56307 Technical Data 1-1 SECTION 1 SIGNALS/CONNECTIONS SIGNAL GROUPINGS The input and output signals of the DSP56307 are organized into functional groups as shown in Table 1-1 . Figure 1-1 diagrams the DSP56307 signals by functional group. The remainder of this chapter describes the signal pins in each functional group. Table 1-1 DSP56307 Functional Signal Groupings Functional Group Number of Signals Power (VCC)20 Ground (GND) 19 Clock 2 PLL 3 Address bus Port A1 18 Data bus 24 Bus control 13 Interrupt and mode control 5 Host interface (HI08) Port B2 16 Enhanced synchronous serial interface (ESSI) Ports C and D3 12 Serial communication interface (SCI) Port E4 3 Timer 3 OnCE/JTAG Port 6 Note: 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. Not Recommended for New Design |
