1.3 Introduction to the CRD48L10 Kit
The main components to be familiar with on the board are:
The main purpose of this board is to allow a customer to evalua te the Cirru s Lo gic CS4 8L 10 DSP a nd othe r Cir rus Log ic
analog semiconductors in a complete audio subsystem.
The Silicon Labs MCU handles the SPI, I²C, and GPIO to control the board components. USB control of the DSP is
possible by connecting the CDB-MCU-DEBUG dongle to the JP2 header.
