2. Connection of Zero-Crossing Detector and Timer Setting
"OR" of [Zero-cross Detector Strobe] or [Compulsion SW of Timer Circuit] moves Internal Analog SW. When for
example, suppose that it set to T = 10 ms.

DATA
Pattern 1
Zero-cross Detector Strobe
(Form signal from insaide IC)
Audio Signal
SW Changing
Pattern 2
Zero-cross Detector Strobe
(Form signal from inside IC)
SW Changing
Audio Signal
In case of Pattern 1, the Zero-cross Detector Strobe occurs with the Zero-cross Detector Function, and SW is switched.
But in case of Pattern 2, the Timer Function switches the Analog SW after T = 10 ms, for the Audio Input Signal didn't
cut the Signal Ground after T = 10 ms which were set with the timer.
Timer Setting Time setting for Frequency band of Input Audio Signal.
