TLV320AIC3104EVM Software

Headset detection features are enabled using the Enable button in the Headset Detection group box.

When enabled, the indicators in the HS/Button Detect group box will light when either a button press or

headset is detected. When a headset is detected, the type of headset is displayed in the Detection Type

indicator. Debounce times for detection are set using the Jack Detect Debounce and Button Press

Debounce controls, which offer debounce times in varying numbers of milliseconds. See the

TLV320AIC3104 data sheet for a discussion of headset detection.

Output short-circuit protection can be enabled in the Short Circuit Protection group box. Short Circuit

Protection can use a current-limit mode, where the drivers will limit current output if a short-circuit

condition is detected, or in a mode where the drivers will power down when such a condition exists.

The I2C Bus Error Detection button allows the user to enable circuitry which will set a register bit

(Register 107, D0) if an I2C bus error is detected.
