The audio circuit is essentially a stereo, 2x2, nonblock-
ing, audio crosspoint with output drivers. The encoder
(stereo audio DAC) and the VCR are the two input
sources, and the two outputs go to the TV SCART con-
nector and the VCR SCART connector. See Figure 1.

The integrated charge pump inverts the +3.3V supply
to create a -3.3V supply. The audio circuit operates
from bipolar supplies so the audio signal is always
biased to ground.
