2.7. Daughterboard Configuration Controller-FPGA serial interface

The Daughterboard Configuration Controller uses a serial communication channel to receive and transmit information to the FPGA on the daughterboard. The FPGA must implement a Serial Configuration Controller (SCC) to support these accesses. See Chapter 3 Programmers Model. See also Application Note 306 Example LogicTile Express 20MG Design for a CoreTile Express A9x4 for an example SCC implementation.

The MCC configures the daughterboard SCC registers on power-up with the values that the daughterboard configuration board file defines. You can also read and write to the SCC registers while the system is running using the motherboard SYS_CFG register interface.
