The CODEC connects to the processor via serial port 1. Two of the Link Ports are routed
to external connectors. The host port of the processor (64 bit parallel port) connects
directly to the Flash memory and the synchronous burst static RAM (SBSRAM). A
programmable logic device (PLD) interfaces the processor’s external port to the parallel
interface. The push button interrupts are de-bounced and then connected to the dedicated
interrupt pins on the processor. The User LEDs from the processor are driven directly by
the processor Flag pins. The Cluster connectors allow the board to be connected into a
cluster configuration with another ADSP-21160 EZ-KIT Lite board (maximum of 2
boards).

2.5.1. Power-on Self Test (POST)
When power is applied to the ADSP-21160 EZ-KIT Lite board or the Master Reset
pushbutton is pressed, the firmware executes a Power-on Self Test (POST) routine.
POST performs the following tests:
1. External (SBSRAM) memory test
2. Internal memory test
3. FLASH memory parity check test
4. CODEC functionality test (tone generator)
During these tests, the three amber user LED’s on the ADSP-21160 EZ-KIT Lite board

2.5.2. Parallel Port Setup
The ADSP-21160 EZ-KIT Lite includes a Parallel Port Setup utility to assist you in
establishing a communication path between the host PC and the ADSP-21160 EZ-KIT
Lite board. EPP mode is the preferred parallel port mode for the ADSP-21160 EZ-KIT
Lite. Bi-directional (PS/2 in some machines) mode is supported as an alternative. Use
this mode only if your parallel port controller does not include EPP mode support.
To configure the port correctly, you must
• Perform a BIOS Setup
• Run the Parallel Port Setup Utility
BIOS Setup
Use your host computer BIOS Setup utility to configure the parallel port. Refer to your
PC motherboard manual for more information. Use the following steps to set up your
host BIOS:
1. Shut down your computer.
2. Reboot your computer, and select the BIOS setup option.
3. In the BIOS setup screen, configure the parallel port for EPP mode.
For example, with a Phoenix BIOS, navigate to
Advanced > Integrated I/O Ports > Parallel Port
and set the port attributes to Auto configuration, EPP mode. (If your I/O port does
not support EPP mode, select bi-directional mode.)
4. Save the changes and reboot.

Parallel Port
Setup Utility
To execute the Parallel Port Setup utility:
1. Connect the ADSP-21160 EZ-KIT Lite to a parallel port on the target PC.
2. Click Start > Programs > VisualDSP++ > Parallel port setup
The Parallel Port Setup utility polls at the default parallel port addresses 0x278 and
0x378. Ports responding as enhanced parallel port (EPP) compatible are tested for the
presence of an ADSP-21160 EZ-KIT Lite board.
The test is performed by writing a loop-back test message to each compatible port. The
resident monitor on the ADSP-21160 EZ-KIT Lite board responds to such messages by
echoing them back to the host. You must therefore first reset your ADSP-21160 EZ-KIT
Lite board to ensure it is properly initialized, and can respond to a poll request. To do so,
1. press the Master
Reset pushbutton on
the board,
2. wait for the board LEDs
to switch off, then click
OK.*
* You may need to wait for 5 seconds when using bi-directional mode on a slower
machine before clicking OK.

Getting Started
The utility displays a screen listing the available EPP mode parallel ports. Select the port
from the list and click O
K to accept the parallel port setup information.
Manual Setup
The utility confirms the address information has been saved in a file in your <etc>
directory. The address information in this file is used by VisualDSP++ to establish a
communication path to the ADSP-21160 EZ-KIT Lite. Click OK to end the utility.
Note: If the parallel port is in bi-directional mode, the bracketed comments
(EPP) are replaced with (bi-directional), indicating the communication
protocol.
If the parallel port on your PC is not at either of the standard addresses (0x278 or 0x378),
use the Manual Setup option to specify its address and mode. When specified
manually, the utility does not poll the address you define. To validate the port you must

test the communication from the VisualDSP++ debugger. From the debugger window
Se
ttings menu, select Test Communications.
When entering the address, use hexadecimal notation as shown below. (for example,
enter ‘0x478’ rather than just ‘478’).
Enter the parallel port address and mode specification, and Click OK. To confirm the
values click OK, or Cancel to return to the setup screen to modify them.
Click OK to end the utility.
If you happen to corrupt the System Definition File (SDF), an original copy is available
on the Installation CD under the Original Files folder.

3.3.1. Loading and Running Programs
To load and run a demonstration program:
1. From the VisualDSP++ debugger window F
ile menu, select Load.
2. Navigate to the directory containing the demonstration program. (Demonstration
programs are installed in directories under <EzKit21160>\examples\dsp\
<demo name>\debug where <EzKit21160> is the root directory where you
installed the ADSP-21160 EZ-KIT Lite software and <demo name> is the
name of the demonstration program.)

ebug menu, select Run.
The VisualDSP++ debugger includes two commands useful for synchronization of your
test code and the resident monitor on the ADSP-21160 EZ-KIT Lite board. Observe the
following rules when using these commands
Command Usage and impact
Debug > Reset
Debug > Restart
Use to reset the board and reload the monitor executive.
Downloaded programs are lost in their entirety and must be
reloaded. POST routines are executed.
Use to restart the monitor executive after a Halt command or the
normal end of execution of a program. The monitor restarts
unambiguously at its main entry point, but retains information
about breakpoints and downloaded code. For programs which run
to normal completion, and which you wish to re-execute, this is
mandatory (Normal program completion halts at a breakpoint
placed over an idle instruction in the monitor. Continuing from this
point causes the monitor to idle forever.)

3.4.1. Fft.dxe
The FFT demo performs a frequency analysis on an analog signal presented to the board.
The program runs continuously, repeatedly acquiring a block of 128 samples from the
Codec, optionally filtering the input samples, applying the FFT and optionally scaling
the results. A demo control panel lets you vary these parameters at run-time. To view the
results you must set a break point in the program. (Data viewing and plotting is not
possible while the program is executing).
To configure your board, and run this demo, use the following procedure.
1. Connect the “Line Out” of an electronic audio device (or microphone) to
connector J6 (Line In) on the board.
