Lattice Semiconductor
The CLK connects directly to the oscillator on the board. The RSTn (global reset) is connected to user push-button
(S1) of the Mini board. The other three inputs come from the SW1 DIP switch bank at the right hand side of the Mini
board.
The outputs of the MachXO device are as follows:
• LED_OUT[7:0]: Most significant eight bits of the counter to be displayed through eight LEDs to show the counter

Programming the Initial Up-Counter Design
To program the up-counter design JEDEC file:
1. Set the control signals with the Mini board SW1 DIP switches as follows:
2. Use ispVM to download the Mini board with the
3. Toggle SW1_2 CNTEN to the OFF (1) position. The LEDs show the up-counter values.
4. Toggle SW1_2 CNTEN to the ON (0) position. Note the up-counter value.
Download the Down-Counter Design to the MachXO Flash Space
To program the down-counter design JEDEC file:
1. From ispVM System, choose ispTools > Scan Chain. The New Scan Configuration Setup window appears.
2. Double-click the LCMXO2280C entry in the Device List. The Device Information dialog appears.
3. From the Data File section click the Browse button. The Open Data File dialog appears.
4. Browse to the .\Demo_MachXO_Mini_TransFR_Down_Counter\project folder, select down_count.jed, and
5. From the Device Access Option section, choose Flash Background Mode.
values in binary format.
• LOADn (SW1_1) is set to 1 (OFF)
• CNTEN (SW1_2) is set to 0 (ON)
• Cap_en (SW1_3) is set to 0 (ON)

See the Programming Demo Designs with ispVM section of this document for details on programming the Mini
board with ispVM.
The up-counter design is first loaded into Flash then immediately into SRAM space. In doing so, the LEDs will
light up, showing the initial value of the counter (all 1s). The SRAM and Flash configuration spaces are now
both programmed with the count-up function.
In the following procedure you will load a down-count function into the MachXO Flash program space. After the
TransFR operation is complete, the down-counter results will be displayed on LEDs.
