2) MIDI IC(YMU783)
The MIDI IC(YMU783, YAMAHA) has three main functions. The first function is MIDI ring-tone
generation. The second function is a digital-to-analog conversion of decoded MP3/AAC data from
MAP(CL8237S4, CoreLogic). The third fucntion is a analog mixing and amplifying of voice signal from
ABB(TWL3016, TI)
