CompactFlash (CF) to Microprocessor (MPU) Setup
This setup provides a standard CompactFlash to MPU interface for high-density FPGA systems. The ability to communicate
with the CF through the MPU port allows the user to perform many operations, such as being able to access application data
or microprocessor programming information from the CompactFlash device.
