... If you want to avoid the acknowledge detection of the audio processor, a simpler µP transmission may be used. Wait one clock and do not check the slave acknowledge of this same clock then send the new data. If you use this approach, there are greater chances of faulty operation as well as decrease in noise immunity. PT2258 pre1.0 URL: http://www.princeton.com.tw 6 Tel : 886-2-29162151 ...
