13. LEDs and Switches

LEDs and switches of the MachXO5T-NX Development Board that can be used in demo and customer designs are
described in this section.

13.1. 8-Position DIP Switch

Four LFMXO5-100T pins are connected to the four switches of SW1, as shown in the circuit design in
DIP switches are connected to logic level 0 when in the ON position, as shown in
One side of each switch is connected to GPIOs within the VCCIO5 bank and pulled up through 4.7 kΩ resistors. The
other side is grounded. The designated pins are connected, as shown in
