ADSP-21479 EZ-Board Evaluation System Manual 1-23
Using The ADSP-21479 EZ-Board
Example programs are included in the EZ-Board installation directory to
demonstrate UART and RS-232 operations.
For more information about the UART interface, refer to the
ADSP-214xx SHARC Processor Hardware Reference .
LEDs and Push Buttons
The EZ-Board has eight general-purpose user LEDs connected directly to
the processor, one EZ-Board power LED, and one board reset LED. The
EZ-board also has five push buttons: four general-purpose push buttons
connected directly to the processor and one push button for a board reset.
Table 1-3 summarizes LED connections to the processor. To use the
LEDs connected to DAI or DPI, configure the respective registers of the
processor. For more information, refer to the
ADSP-214xx SHARC Proces-
sor Hardware Reference .
Two general-purpose push buttons are attached to the flag pins of the pro-
cessor, while the other two are attached to the DAI pins. All of the push
buttons and LEDs are connected to the processor through DIP switches.
