Forum Post: DSP memory space data/program

Hi, 

This is a basic question; can some one tell me how can I select to address either data or program space in DSP RAM memory?

Please Refer to  figure below  for 'C5402 memory map.

say that I want to address DSP on-chip RAM by an external device (through HPI), and i have two section:

-- section A to be loaded on program memory start @ 0x100

-- section B to be loaded on dat memory start @ 0x100

so how can I do that ?
