USB Monitor LED (ZLED3)
The USB monitor LED indicates that USB communication has been ini-
tialized successfully, allowing you to connect to the processor using
VisualDSP++. If ZLED3 is not lit, try resetting the board and/or reinstalling
the USB driver.
L When VisualDSP++ is communicating with the EZ-KIT Lite tar-
get board, the LED can flicker, indicating communications
handshake.
Programmable FLAG Push Buttons (SW6–9)
Four push buttons are provided for general-purpose user input. The SW6–9
push buttons connect to the processor’s programmable FLAG pins. The
push buttons are active high and when pressed, send a high (1) to the pro-
cessor. Refer to “Programmable FLAG Pins” on page 1-10 for more
information on how to use the flags. Table 2-19 shows the FLAG signals
and corresponding switches.
