Lattice Semiconductor
DDR registers of the complementary PIO are used in this mode. The complementary PIO register can no longer be
used to perform the DDR function. There are two clocks going to this primitive. The ECLK is connected to the faster
edge clock and the SCLK is connected to the slower FPGA clock. The DDR data output of this primitive is aligned
to the faster edge clock.
Figure 11-38 shows the primitive symbol for the ODDRX2B mode.
