General Configuration Tab

The “General Configuration” tab provides high-level control of signal routing on the CDB43L21. This tab also
includes basic controls for the CS43L21 for quickly setting up the CDB43L21 in simple configurations. Sta-
tus text detailing the CS43L21’s specific configuration is shown in parenthesis or 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:

CS43L21 Basic Configuration - Includes basic register controls in the CS43L21 used for setting up power
status, interface format and clocking functions. See

Section 2.2

and

Section 2.3

for more controls in the

CS43L21.

S/PDIF Receiver Control - Includes all available Hardware Mode controls for setting up the CS8415.

Clock/Data Routing and CS43L21 Reset - Includes controls used for routing clocks and data between the
CS43L21, CS8415, oscillator and the I/O stake header. Also includes a reset control for the CS43L21.

Update - Reads all registers in the FPGA and CS43L21 and reflects the current values in the GUI.

Reset - Resets FPGA to default routing configuration.
