Figure 6. LED/Jumper Order
LEDs D3 through D33 can be used to indicate the state of GPIOs 1 through 8. When it is desired
that the LED is “ON” when the GPIO is “LOW”, the associated jumper should be set to the “UP”
state. With this setting a GREEN LED will be illuminated. When it is desired that the LED is “ON”
when the GPIO is “HIGH”, the associated jumper should be set to the “DN” state. In this case, an
AMBER LED has been incorporated in the circuit. Care should be taken when selecting the
LED polarity of the GPIO which also function as strap inputs.
For additional information about the functionality of pins connected to the LEDs (with the
exception of D2), refer to the DP83630 datasheet.
