3.2.2 Project Menu
A project is a collection of firmware modules and configurations downloaded to the DSP to process audio in a specific way.
For the CRD48L10-4in4out, the Project also defines how the board is configured and data is routed to/from the CS48L10.
The Project menu selection on the LCD appears as shown in
Fig. 3-16 .
