Programming an audio app requires setting the sample frequency with RSL10. How is this sample frequency obtained?
For example, to find the sample rate of DIMC, see the example below:
We set RF_clk = 48M/6 = 8M
And let SYS_clk = RF_clk
Then set audio_clk = 8M/4 = 2M
Set DMIC_clk = audio_clk
Final set sample rate = 2M/64 = 32k
You can use a similar method to get the OD output sample rate; it should work out to 16k.
