Programming the Daisy Chain
(see Appendix A, Figure 23)
This board includes three Lattice programmable (U1=LFE395, U17= LCMXO1200C, and U13 = POWR1220AT8)
devices that can be programmed in a daisy chain. The board also includes a mechanism to daisy chain other Lat-
tice evaluation boards that use the same connector standard.
