3.3.2 Connection between user configurable FPGA (XILINX) and DDR2
(Note) Signal directions indicated as inputs and outputs
are referencing to the user FPGA. “Input” means a
signal from the DDR2 to the user FPGA
and “output” means from the user FPGA to DDR2.
Please sets Float, Pull-up or Pull-down for unused input and I/O signal of the user configurable FPGA.
Please sets Pull-up or Pull-down, or sets [H] or [L] with RTL code, for unused output signal of the user
configurable FPGA.
