LEDs and Push Buttons
This section describes the functionality of the LEDs and push buttons.
Figure 2-6 shows the LED and push button locations.
General Purpose LEDs (LED1–8)
There are eight general-purpose LEDs on the board. Five LEDs connect to
the DPI interface, two LEDs connect to the DAI interface, and one LED
connects to
FLAG3 of the processor. “LEDs and Push Buttons” on
page 1-10 summarizes the LED connections. In order to use the LEDs
connected to the DAI or DPI, the respective registers inside the processor
must be correctly configured. For more information on how to program
the pins, refer to the ADSP-2136x SHARC Processor Hardware Reference
for ADSP-21367/8/9 Processors.
Power LED (LED9)
When LED9 is lit (green), it indicates that power is being properly supplied
to the board.
