-------------------------------------------------------------------------------
Example:  ADSP-21369 EZ-KIT LITE Push Button Example
Target:   ADSP-21369
Date:     July 29, 2005
Tools:    VisualDSP++ 4.0
Hardware: ADSP-21369 EZ-KIT LITE
-------------------------------------------------------------------------------

This directory contains an Assembly code example pushbutton blink for use with
the ADSP-21369 Ez-Kit Lite Development System.

The project illustrates how to use the push buttons on the board in order to
blink the on board LEDs.  On the board the pushbuttons are connected to the
IRQ0, IRQ1, DAI_PB19, and DAI_PB20 signals on the DSP. The DAI signals can be
routed to the miscellaneous channels (MISCAx) which are associated with DAI
interrupts. The IRQ signals have dedicated interrupts. In the example code,
DAI_PB19 is routed to MISCA1 which is associated with DAI interrupt 29 and
DAI_PB20 is routed to MISCA2 which is associated with DAI interrupt 30.

Pressing IRQ1 lights LED1&2 and pressing IRQ0 lights LED3&4.
Pressing DAI_PB19 lights LED5&6 and pressing DAI_PB20 lights LED7&8.
