DSP Engine Tab
The “DSP Engine” tab provides high-level control of the SDIN (PCM) data volume level, the ADC out-
put/SDIN mix volume level and the overall DAC/PWM channel volume level. DAC/PWM channel Limiter,
Tone Control and Beep Generator control functions are also provided. Status text detailing the CODEC’s
specific configuration is shown in parenthesis or inside the control group of the affected control. This text
will change depending on the setting of the associated control. A description of each control group is out-
lined below (a description of each register is included in the CS42L52 data sheet):
Digital Volume Control - Digital volume controls and adjustments for the SDIN data, ADC out data and over-
all channel volume. Mute, gang, invert and de-emphasis functions are also available.
Limiter - Configuration settings for the Automatic Level Control (ALC).
Tone Control - Bass and treble volume controls and filter corner frequencies.
Beep Generator - On/Off time, frequency, volume, mix and repeat beep functions.
Update - Reads all registers in the CS42L52 and reflects the current values in the GUI.
Reset - Resets the CS42L52.
