When configured as Master, SCLK and LRCK/FSYNC are outputs from the CDB53L30. When configured as Slave,
SCLK and LRCK/FSYNC are inputs to the CDB53L30.

Device and Revision I.D.—Displays the CS53L30 revision information.

Refresh—Reads all registers in all devices and updates the values in the FlexGUI.
