General Purpose LEDs (LED1–8)
There are eight general-purpose LEDs on the board. Five LEDs are con-
nected to the DPI interface, two LEDs are connected to the DAI interface,
and one LED is connected to
FLAG3
of the processor. “LEDs and Push
Buttons” on page 1-15 summarizes the LED connections. To use an LED
connected to the DAI or DPI, program its respective register on the pro-
cessor. For more information on how to program the registers, refer to the
ADSP-2137x SHARC Processor Hardware Reference (Includes
ADSP-21367, ADSP-21368, ADSP-21369, ADSP-21371, ADSP-21375)
.
Power LED (LED9)
When
LED9
is lit (green), it indicates that power is being supplied to the
board properly.
Reset LEDs (LED10)
When
LED10
is lit (red), a master reset of all the major ICs is active.
USB Monitor LED (ZLED3)
The USB monitor LED (
ZLED3
) indicates that USB communication has
been initialized successfully, and you can connect to the processor using
an EZ-KIT Lite session. Once the USB cable is plugged into the board, it
takes approximately 15 seconds for the USB monitor LED to light. If the
LED does not light, try cycling power on the board and/or reinstalling the
USB driver.

When the development software is actively communicating with
the EZ-KIT Lite target board, the LED can flicker, indicating
communications handshake.
