Table 5. ispVM JTAG Connector (J28)
This board includes three Lattice programmable devices that can be programmed in a daisy chain (U30 =
LatticeECP3-95, U1 = MachXO™ LCMXO256, and U36 = ispPAC-POWR1220AT8). Other than the LatticeECP3-
95, the JTAG connector provides access to the JTAG ports of the ispPAC-POWR1220AT8 and the MachXO. With
proper jumper selection, the JTAG ports of these devices can be chained together for programming. Table 6 shows
the jumper settings of J32, J33 and J34 used to configure the JTAG connections.
