用四个EEPOT实现音频音调 平衡 音量控制

Imagine the possibilities of being able to integrate full

audio tone, balance, and volume control into your

multimedia computer product, without having to

resort to any manual knobs. Naturally you could do

that with a bunch of DACs all running under

microprocessor control, but what happens if the audio

amplifiers and sound generators come alive before

the processor has had a chance to reload the preset

values into the DACs. You could get blasted before

the initialization sequence is complete.
