3.3.4 DSP I/O Space Memory Map
The DSP I/O space is a separate address space from the data/program memory space. The I/O space is accessed via the DSP’s port instructions. The DSP I/O space is accessed using 16-bit word addresses.
Table 3−70 to Table 3−82 specify the DSP base addresses where each set of registers is accessed. All accesses to these registers must utilize the appropriate access width as indicated in the tables. Accessing registers with the incorrect access width may cause unexpected results, including a TI Peripheral Bus (TIPB) bus error and associated TIPB interrupt.
3.3.4.1 DSP Private Peripheral Registers The DSP Private Registers include the following:
• DSP DMA Controller Registers
• DSP Timer1 Registers
• DSP Timer2 Registers
• DSP Timer3 Registers
• DSP Watchdog Timer Registers
• DSP Level 2.0 Interrupt Handler Registers
• DSP Interrupt Interface Registers
• DSP Level 2.1 Interrupt Handler Registers
