Electronic volume controllers
The IC incorporates microphone input 1 (MIC1) and microphone input 2 (MIC2) volume and echo volume
controllers. The built-in volume controller operates in 16 steps. Using an external variable resistor, volume
can be controlled by the DC level or from the MCU using serial data.
The TC9455F/N supports an I2C bus interface; the TC9488F/N, a three-lead interface.
