Max PGA applicable allows the user to restrict the maximum gain applied by the AGC. This can be used

for limiting PGA gain in situations where environmental noise is greater than the programmed noise

threshold. Microphone input maximum PGA can be programmed from 0 dB to 59.5 dB in steps of 0.5 dB.

Programming the maximum PGA gain allowed by the AGC is done by writing to page 0 / register 88,

bits D6–D0.

See Table 5-16 for various AGC programming options. AGC can be used only if the microphone input is

routed to the ADC channel.
