One PDSP block is a combination of a specialized 64-slot RISC-based digital signal processor (DSP), a general-purpose 16-bit CISC-based control processor (P16), a cache memory and an “intelligent” peripheral I/O interface. Both PDSPs are fully independent and share the same external memory through the MMU. 1772D–DRMSD–01/04 Block Diagrams Figure 1.

Power Group Name GND VC3 VCC1 VCC2 Pin Count 19 8 5 5 Type PWR PWR PWR PWR Function Power Ground. All GND pins should be returned to digital ground. Core Power, +3.3V nominal (3V to 4.5V). All VC3 pins should be returned to +3.3V. Pad (except Memory Pad) Power, +3.0V to +5.5V. All VCC pins should be returned to +5V (or 3.3V in case of single 3.3V supply). Memory Pad Power, +3.0V to +5.5V. All VCC pins should be returned to +5V (for RAM or DRAM) or 3.3V (for SDRAM or 3.3V ROM). Table 2. ISA Bus Group(1) Name PC_D[15:0] (2, 3) Pin Count 16 Type I/O Function 16-bit data bus to host processor. Information on these pins is: - 2 x parallel MIDI (MPU-401 type applications) - 2 x high-speed burst data transfers to/from external memory Selects one of 8 internal registers: 0, 1: MPU-401 register processor #1 2, 3: Burst data (16-bit) processor #1 4 - 5: MPU-401 register processor #2 6 - 7: Burst data (16-bit) processor #2 Chip select from host, active low. Write from host, active low. Read from host, active low. Open drain output buffer. Driven low during 16-bit burst mode transfers to synchronize host to the ATSAM9708 memory. Open drain output buffer; driven low during 16-bit burst mode transfers. Indicates to host that a 16-bit I/O is in progress. Tri-state output pin, active high. Can be connected directly to host PC_IRQ line. PC_A[2:0] 3 IN PC_CS(4) PC_WR PC_RD PC_READY PC_IO16 PC_IRQ Notes: 1 1 1 1 1 1 IN IN IN TSout TSout TSout 1. ISA bus group pins are powered by VCC1 power rail. 2. PC_D pads have 4 mA drive capabilities; other output pads have 16 mA drive capabilities. 3. To interface with PC ISA bus, VCC1 should be connected to 5V power and PC_D bus should be buffered. Direction is given by PC_RD signal. 4. Pin Names in this document exhibiting an overbar (PC_CS for example) indicates that the signal is active low. 3 1772D–DRMSD–01/04 Table 3.
