Leds And Push Buttons - Analog Devices ADSP-21479 EZ-Board Manual

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.
