this special vertical routing channel and the eight secondary clock regions for the ECP2-50. LatticeECP2 devices
have eight secondary clock and control signal resources per region (SC0 to SC7).
The secondary clock muxes are located in the center of the device. Figure 2-16 shows the mux structure of the
secondary clock routing.
