4. DAC Configuration Application (AN721SW)
The DAC Configuration utility is an application within the AN721 software (AN721SW) package that allows audio
configuration strings to be sent to the CP2114 one-time programmable memory or RAM. The audio string is used
by the CP2114 to configure the DAC/CODEC. To access the DAC Configuration utility, run the AN721SW and
connect to the CP2114 device.
After connecting to the device, select Advanced Configuration, then DAC Configuration. After this, the DAC
Configuration utility shown in Figure 5 will appear. This AN721SW package is available at www.silabs.com/CP2114.
4.1. Application Command Descriptions
4.1.1. Get CP2114 Capabilities
This button will report the current configuration of the one-time programmable memory. With the default pin
configuration and no jumpers installed on GPIO.5, GPIO.6, GPIO.7, or GPIO.8, the utility will display the following:
The AvailableBootIndices: 0x20 parameter indicates that all 32 boot index slots are available for programming.
The AvailableOtpConfigs: 0x1D parameter indicates that there are 29 CP2114 configurations available in the
one-time programmable memory.
