USING SIGMASTUDIO

The AD1940 does not pass an audio signal on power up. First,
the user must write to bit 9 of the DSP Core Control Register,
which will allow data to pass from input to output. This
procedure may be done manually, but this bit is always set to 1
after the program and parameter loading procedure is
completed by clicking the Link-Compile-Download button in
SigmaStudio. For more information about using SigmaStudio
with the evaluation board, please read the software's online
help document.
Software updates are provided via Analog Devices' FTP site.
