Hardware is done. It does not evolve. Will reprhase, thanks. For sure hardware is done, but I'm afraid I could miss some functionality because I have access only to public documentation and it is not full enough. For example there is some kind of amplification limiter register field but there is no information for now how it should be used. > > Write complete bindings, see writing-bindings document. > > Best regards, > Krzysztof >
