Hi Dave,
Thank you for your reply.I'm still a little confused about the mode setting.In this case, I should use Raw Pixel Mode to input pixel data on VDATA bus,and use Normal Host Mode to output compressed data on HDATA bus. So even if I set the BUSMODE register for Normal Host Mode,I can still use Raw Pixel Mode to input data. Is that correct??
Another question, Must I use VFRM,VRDY and VSTRB pins to input data on VDATA bus? If it has some break between pixel datas,I mean pixel datas can not be inputed in a row,should I pull down VSTRB signal when data is not valid?
