devices have six secondary clock regions. All devices in the LatticeXP2 family have eight secondary clock
resources per region (SC0 to SC7).
The secondary clock muxes are located in the center of the device. Figure 2-12 shows the mux structure of the
secondary clock routing. Secondary clocks SC0 to SC3 are used for high fan-out control and SC4 to SC7 are used
for clock signals.
