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
