      Driving Signals to the ESB
      ESBs provide flexible options for driving control signals. Different clocks
      can be used for the ESB inputs and outputs. Registers can be inserted
      independently on the data input, data output, read address, write
      address, WE, and RE signals. The global signals and the local interconnect
      can drive the WE and RE signals. The global signals, dedicated clock pins,
      and local interconnect can drive the ESB clock signals. Because the LEs
      drive the local interconnect, the LEs can control the WE and RE signals and
      the ESB clock, clock enable, and asynchronous clear signals. Figure 24
      shows the ESB control signal generation logic.

      Note:
      (1)
      APEX 20KE devices have four dedicated clocks.
      An ESB is fed by the local interconnect, which is driven by adjacent LEs
      (for high-speed connection to the ESB) or the MegaLAB interconnect. The
      ESB can drive the local, MegaLAB, or FastTrack Interconnect routing
      structure to drive LEs and IOEs in the same MegaLAB structure or
      anywhere in the device.
