BLOCK DIAGRAM
This LSI has two input channels (L and R) and two output channels (L and R) for digital audio interface. It also has a
one bit Delta-Sigma type AD converter 1 channel (microphone) that performs Delta-Sigma modulation at its analog
block, and decimation/interpolation of 128 times at its DSP.
Karaoke audio signal is processed by DSP for processing Karaoke audio signal and RAM for delay.
For the details of Karaoke audio signal processing, please refer to "OPERATIONS".
The parameters of this LSI are set through CPU interface. For the details of the parameters, please refer to
"REGISTERS".

Description
KP2
standard mode
N
The functions of KP2 (YSS216B) can be used. The registers are compatible, except that
the coefficient registers (addresses $27 and $30 to $33) of KP2 that controls the analog
audio input and analog microphone echo output cannot be used because YSS903 does
not have these ports.
KP2V
extended mode
E Every function of this device can be used.
