Volume up control input pin.
The 1 step/1 push volume is controlled by pressing the
up Key. If the key has been pushed continuously
increase. Built-in pull-up resistor.
Volume down control input pin.
The 1 step/1 push volume is controlled by pressing the
down Key. If the key is continuously pressed, the
volume control will continuously decrease. Built-in
pull-up resistor.
Oscillation pin.
The oscillation circuit of a resistor and capacitor
connection. Oscillator is activated when the key is
pressed.
Reset pin.
This pin sets the initial volume level. The volume level is
set to -46dB by “L” Input. Built-in pull-up resistor low
