USING SIGMASTUDIO
The AD1940/AD1941 do not pass an audio signal on power-up.
First, the user must write to Bit 9 of the DSP core control
register that allows data to pass from input to output. This
procedure can be done manually. Bit 9 is always set to 1 after
the program and parameter loading procedure is completed by
clicking the
Link-Compile-Download
button in SigmaStudio.
Refer to the software’s online help document for additional
information about using SigmaStudio with the
AD1940EB/AD1941EB.
