HIGHPASS FILTER
The WM8940 has a selectable digital high pass filter in the ADC filter path. This filter has two modes,
audio and applications. In audio mode the filter is a 1
st order IIR with a cut-off of around 3.7Hz. In
applications mode the filter is a 2
nd order high pass filter with a selectable cut-off frequency.
