4.3. VSEC Registers for CvP

The Vendor Specific Extended Capability (VSEC) registers occupy byte offset 0x200 to 0x240 in the PCIe Configuration Space. The PCIe host uses these registers to communicate with the FPGA control block. The following table shows the VSEC register map. Subsequent tables provide the fields and descriptions of each register.
