Regarding to TRM, I can select Nyquist Zone of ADC by setting register 70h.
I am not clear what is happen if I select nyquist zone 2.
Does 'selecting nyquist zone 2' mean that BPF for nyquist zone 2 will be applied before ADC sampling? Thus there is no need to put BFP outside?
If my application use nyquist zone 7, which registers should I set?
