Interesting... I'm sure you've already tried this as one of the undocumented registers in the bt878, right? I have so far only tried all options in the so-called undocumented TEST register. The only thing I could get it to do is not-syncing, no output or crash It is hard to try out all options because you have to setup a risc program in memory to get the exact amount of samples the card is sending. So in some undocumented place you have to set this packet size In another undocumented place you have to enable the right mode Then setup the risc program accordingly. If the bt878 can do it I hope to find out how, but it takes a lot of trying and guessing.
