utilizing FM synthesizerand ADPCMdecoderthatareincludedinthisdevice.

Asasynthesis,YMU762MA3isequipped 32 voiceswith different tones.Since thedevice is

capableofsimultaneously generating up tosynchronouswiththeplay oftheFM synthesizer,

various sampled voicescan beusedas sound effects.

Since theplay dataofYMU762MA3areinterpretedatanytimethrough FIFO,thelength ofthe

data(playing period)isnot limited, sothedevice canflexiblysupportapplication suchasincoming

call melody musicdistribution service.Thehardwaresequencerbuilt inthisdevice allowsplaying
