Reset LED (LED9)
When LED9 is lit (red), the master reset of all the major ICs is active.
Power LED (LED10)
When LED10 is lit (green), it indicates that power is being supplied to the
board properly.
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 a
VisualDSP++ 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 (see the VisualDSP++ Installation Quick Refer-
ence Card).

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