Board Configuration Tab

The “Board Configuration” tab provides high-level control of signal routing on the CDB43L22. This tab also
includes basic controls that allow “quick setup” in a number of simple board configurations. Status text de-
tailing the CS43L22’s specific configuration appears directly below the associated control. This text may
change depending on the setting of the associated control. A description of each control group is outlined
below:

CS43L22 Basic Configuration - Includes controls for configuring the interface format, clocking functions and
analog input signal routing in the CS43L22. See

Section 4.2

through

Section 4.4

for more controls in the

CS43L22.

CS8416 S/PDIF Receiver Control - Register controls for setting up the CS8416.

Clock Source and Routing Selection - Includes controls used to configure the value and source of the mas-
ter, frame and bit clocks which are sent to the CS43L22.

Update - Reads all registers in the FPGA, CS43L22 and the CS8416 and shows the current values in the
GUI.

Reset - Resets FPGA to default routing configuration.
