Lattice Semiconductor
• D12 (green) will flash indicating TDI activity.
• D10 (red) illuminated, this indicates that PROGRAMN is low.
• D9 (red) illuminated, this indicates that GSRN is low.
PROGRAMN & GSRN
(see Appendix A, Figure 23)
• These push-button switches assert/de-assert the logic levels on the PROGRAMN (SW3) and GSRN (SW2).
• These push-buttons are accessible from the back panel if the evaluation board is mounted in a PCI Express slot
CFG [2:0]
(see Appendix A, Figure 23)
• The FPGA CFG pins are set on the board for a particular programming mode via the SW1 DIP switch.
• JTAG programming is independent of the MODE pins and is always available to the user.
• Pushing in (depressing) the switch is ON and sets the value to 0.

On-Board Serial SPI Flash Memory
(see Appendix A, Figure 23)
• One Serial SPI (16-pin tssop 64M) Flash memory device (U8) is on-board for non-volatile configuration memory
• All CFG [2:0] need to be [000] depressed to read the Flash memory at power-up or after toggling the PRO-
Programming Serial SPI Flash Memory
The Serial SPI Flash memory device can be configured easily via its JTAG port. This mode enables the FPGA to
be programmed at power-up or assertion of PROGRAMN with a bitstream stored in the memory device.
1. Connect the LatticeECP2M PCI Express Solutions Board to the appropriate power sources and power-up
2. Connect the ispDOWNLOAD cable to the appropriate header. J3 is used for the 1x10 cable.
3. Start the ispVM System software.
4. Press the SCAN button located in the toolbar. The LFE2M50E and the LCMXO1200C devices should be auto-
Depressing the button drives a logic level “0” to the device.
