Push-button Switches (SW6, SW7, SW8, SW9 and SW10)
Five push-buttons can also be used to provide inputs that require pulses. There are de-bouncers between the
push-buttons and the LatticeECP3 to remove the glitches of the push-button signals. When pressing these push-
buttons, logic 0 will be sent to the connected LatticeECP3 pins. Table 31 shows the corresponding pin connections
between the push-buttons and the LatticeECP3 pins.

Discrete LEDs (D10~D17, D22~D24, and D26)
There are 12 discrete LEDs for use as status indicators. These 12 LEDs are divided into three groups, (D10, D11,
D12, D13), (D14, D15, D16, D17) and (D22, D23, D24, D26). Each group has four LEDs and each LED is in a dif-
ferent color. Table 32 shows the pin connections and colors of these LEDs.
