Figure 12-29 shows the primitive symbol for the IDDRFXA mode.
Figure 12-29. IDDRFXA Symbol
Table 12-8 lists the port names and descriptions for the IDDRFXA primitive.
Table 12-8. IDDRFXA Port Names
Figure 12-31 shows the LatticeECP2 Input Register Block configured in the IDDRXFXA mode. CLK1 used to regis-
ter the DDR registers and the first set of synchronization registers. CLK2 is used by the third stage of registers and
should be clocked by the FPGA clock. These clock transfer registers are shared with the output register block.
