Hi DSP guru, I am programming for ADSP21061. The code was developed by other developer who left long time ago. I am trying to understand his code, but I don't have experience on DSP at all. The DSP is used as a slave that is listening to the command sent from the master Micro controller. These interface signals include IRQ0, dsp_data[31:0] SPR0I, etc. Accordin
