Supported Ports
Data Port 1 (High Quality Mode) Active Data Port 2 (Low Power-Listen Disabled Mode) Control Port Active
Note 2:
Sensitivity is relative to the RMS level of a sine wave with positive amplitude equal to 100% 1s density and negative amplitude equal to 0% 1s density.
Note 3:
fswclk should be an integer multiple of the desired Mic Data Rate see table 14 with permissible fswclk and Mic Data Rates.
