Additional Features
10.1
Key Click Sound Generator
The Key Click Sound Generator allows the MPR083 to generate audible feedback, independent of the I2C communication status.
The sounder is used to drive a piezo buzzer. This output is configured by using the Sounder Register, shown in the following
section.
10.1.1 Sounder Configuration Register
The I2C slave address of the Sounder Configuration Register is 0x07.

10.2
Sensor Information
The Sensor Information register is a read only register that displays a descriptor which contains static information about the
MPR083 version.
10.2.1 Sensor Information Register
The I2C slave address of the Sensor Information Register is 0x0B.
