DA7217 Register Setting

Hi,

We just started a new design based on DA7217. The design uses two analog mics and I2S out to a host processor. No headphone is used. I wonder if there are any application notes about setting up the registers for this codec.

Thanks,

Here is one more question regarding this DA7217:

Since we do not use headphone no charge pump, how do we connect the following pins:

HPCSP
HPCSN
HPCFP
HPCFN

Can we leave the above pins float?

Thanks,
