User LEDs (LED2–6)

Five LEDs connect to five general-purpose IO pins of the processor (see Table 2-15). The LEDs are active high and are lit by writing a 1 to the correct PC signal. Refer to “LEDs and Push Buttons” on page 1-13for more information about how to use flash memory when programming the LEDs.

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. This takes approximately 15 seconds. If the LED does not light, try cycling power on the board and/or re-installing 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.
