SSM2529 Standalone Mode volume control

I'm planning the simple circuit whichconnects a MEMS microphone to a device directly in STAND-ALONE-MODE SSM2529.

I checked SSM2529 datasheet figure43:Hardware Standalone Mode.

How much resistance value should be connectedto SCL/SDA terminal?(and ADDR)

Please show me a relation between the gain and the resistance value.

Is the volume current control or voltage control?

I'm planning the simple and light circuit. Is there more advice? (I checked bypass condenser.)

Please advise me.
