Memory Configuration
3.6 RAM Configuration Summary
The RAM configurations for the DSP56309 are listed in Table 3-1.
The actual memory locations for Program RAM and the Instruction Cache in the Program
memory space are determined by the MS and CE bits, and their addresses are given in Table 3-2.
3.7 Memory Maps
The following figures describe each of the memory space and RAM configurations defined by
the settings of the SC, MS, and CE bits. The figures show the configuration and the table
describes the bit settings, memory sizes, and memory locations.
