s GENERAL DESCRIPTION
The NJW1140 is a sound processor includes all of the
functions required to process the audio signal for TV, such
as tone control, balance, volume, mute, and AGC functions.
Also the NJW1140 performs SRS 3D Stereo which
regenerates 3D surround sound with only two speakers.
All of the internal status and variables are controlled by
I2C BUS interface.
