TLV320AIC34EVM Software
Headset detection features are enabled using the Enable button in the Headset Detection groupbox.
When enabled, the indicators in the HS/Button Detect groupbox 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
TLV320AIC34 data sheet for a discussion of headset detection.
Output short-circuit protection can be enabled in the Short Circuit Protection groupbox. 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 I
2
C Bus Error Detection button allows the user to enable circuitry which will set a register bit
(Register 107, D0) if an I
2
C bus error is detected.
