Interrupt Output. This is an open-drain output that pulls down to GNDVID to
indicate a change in the VCR slow switching or fast switching input, the activity
status of the composite video inputs, or the load status of the composite video
outputs.
Audio Supply. Connect to a 3.3V supply. Bypass with a 10µF aluminum
electrolytic capacitor and a 0.47µF ceramic capacitor to EP.
Charge-Pump Flying Capacitor Positive Terminal. Connect a 0.47µF capacitor
from C1P to C1N.
Charge-Pump Flying Capacitor Negative Terminal. Connect a 0.47µF capacitor
from C1P to C1N.
