Table 6. JTAG Connection Settings (J32, J33, J34) (Continued)
There are several LEDs on the board to indicate the LatticeECP3 programming status. They are listed in Table 7.
Table 7. LED Indicators for Configuration Status
The PROGRAMN pin of the LatticeECP3-95 is connected to a push-button switch (SW5). Depressing this button
drives a logic level “0” to the PROGRAMN pin. This will force the LatticeECP3 into the configuration mode and initi-
ate the configuration sequence.
The FPGA CFG pins are set on the board for a particular programming mode via the SW2 DIP switch. JTAG pro-
gramming is independent of the MODE pins and is always available to the user. Pushing down the switch will turn it
on and set the CFG value to 0.
