Using EZ-KIT Lite

Two of the general-purpose push buttons are attached to the FLAG pins of the processor, while the other two are attached to the DAI pins. All of the push buttons connect to the processor through a DIP switch. The DIP switch allows processor pins, which connect to the push buttons, to be dis- connected. See “Push Button Enable Switch (SW7)” on page 2-12for instructions on how to disable the push buttons from driving the corre- sponding processor pin.

The state of the push buttons, connected to the FLAG pins, can be deter- mined by reading the FLAG register. The push buttons connected to the DAI pins must be configured as interrupts. It is necessary to set up an interrupt routine to determine each pin’s state. Table 1-2shows how each push button connects to the processor. Refer to the related example pro- gram shipped with the EZ-KIT Lite for more information.

Table 1-2. Push Button Connections

PB1	SW8	FLAG1/~IRQ1

PB2	SW11	FLAG0/~IRQ0

PB3	SW10	DAI19

PB4	SW9	DAI20

Table 1-3summarizes the LED connections to the processor. In order to use the LEDs connected to the DAI or DPI, the respective registers inside the processor must be correctly configured. For more information on how to program the pins, refer to the ADSP-2136x SHARC Processor Hardware Reference for ADSP-21367/8/9 Processors.

An example program is included in the EZ-KIT Lite installation directory to demonstrate the functionality of the LEDs and push buttons.
