IDC10 socket for ADI USBI downloader, ADI USBI actual port pin number is 10, in AN1006 note described as IDC14.
you can program it with sigma software,full function programming for DSP and open access environment. we find some customer development PC software with such DSP only have few function and mcu controller works condition not good as idea.

How do you control the reset pin without a microcontroller? Do you use a special circuit for this? I am very interested in this detail.

I thougth this is a diy forum
My amplifier is already build, but I wanted to eliminate the *speaker-plop*.

Maybe I will try the TL7712 Reset circuit.

If you would like to share your reset circuit, a pm is very appreciated.

Kind regards,
max
