Figure 8-1 Boundary Scan Operation Schematic Diagram
The boundary scan operation can only be performed on the external
Flash of FPGA and cannot be used to program the embedded Flash or
SRAM. This operation is irrelevant with the FPGA MODE value, but it is
slower than that of the external Flash programming via JTAG.
