PREFACE
Thank you for purchasing the ADSP-2189M EZ-KIT Lite®, Analog
Devices (ADI) evaluation system for ADSP-2189 DSPs.
The ADSP-2189M DSP is a single-chip microcomputer optimized for
digital signal processing (DSP) and other high-speed numeric processing
applications.
The evaluation board is designed to be used in conjunction with
VisualDSP++™ development environment to test the capabilities of the
ADSP-2189M DSPs. The VisualDSP++ software gives you the ability to
perform advanced application code development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C and ADSP-2189M assembly
• Load, run, step, halt, and set breakpoints in application program
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory
Using the EZ-KIT Lite with VisualDSP++, you can observe the
ADSP-2189M processor execute programs from on-chip RAM, interact
with on-board devices, and communicate with other peripherals located
on optional add-on modules.
viii ADSP-2189M EZ-KIT Lite Evaluation System Manual
You can access the ADSP-2189M processor from a personal computer
(PC) through a serial port or an optional emulator. The monitor program
gives you complete target debug capability through the serial port. In con-
trast, the emulator allows the PC to perform in-circuit emulation through
the processor’s emulation port.

•“Flags” on page 2-4
•“Interrupts” on page 2-4
•“Serial Ports” on page 2-5
Flags
The ADSP-2189M processor has one asynchronous FLAG IO pin, FL1. The
pin is connected to the amber FL1 LED. This lets you visually inspect
states of your program. The other nine programmable flags (PFs) connect
to the expansion area.
Interrupts
The ADSP-2189M EZ-KIT Lite has one external interrupt connected
through a push button switch, SW1. This corresponds to an external inter-
rupt, IRQE.
The external interrupts are controlled through the ICNTL and IMASK regis-
ters and are configured by modifying the interrupt vector table or through
instructions in user code. The ICNTL register also controls the interrupt
sensitivity between level and edge. To prevent an interrupt from being
masked, write to the IMASK register.
The monitor program running on the ADSP-2189M processor uses one
interrupt (Timer) for normal operation. When downloading your own
code through the monitor program, the timer interrupt vector is protected
and cannot be overwritten. If these vectors are overwritten, or the timer

Using EZ-KIT LITE Software
interrupt is masked in any way, the debugger is not able to communicate
with the host program. The following rules and restrictions should be fol-
lowed when using interrupts.
• You cannot step into an interrupt
• Interrupts are disabled when the user program is halted
• The board cannot communicate with the host if interrupt nesting
is enabled.
• If you do not require the supplied monitor program, a start-up rou-
tine that dynamically alters the Timer interrupt vector can be used.
This removes all monitor function.
Serial Ports
The ADSP-2189M DSP features two synchronous bi-directional Serial
Ports (SPORTs), SPORT0 and SPORT1. The SPORTs can operate at up to
1x clock frequency, providing each with a maximum data rate of
30 Mbit/sec. SPORT data can be automatically transferred to and from
on-chip memory using DMA.
SPORT0 is connected to the on-board AD73322 codec. The JP2 jumper can
be used to disable the codec. SPORT1 is connected to the RS-232 interface
and is used as a software Universal Asynchronous Receiver/Transmitter
(UART). Communications between the monitor and the host are through
SPORT1, which can be disabled withe the J6 jumper.
For more information on the Serial Ports, refe r to the ADSP-218x DSP
Hardware Reference.
POST Routines
Power On Self-Test (POST) routines are a series of standard tests and ini-
tializations that the ADSP-2189M EZ-KIT Lite performs on a power-on
reset. To perform a power-on reset, disconnect power to the board for at
Standard Operations
2-6 ADSP-2189M EZ-KIT Lite Evaluation System Manual
least three seconds and then reconnect power. The board automatically
resets (note that all the LEDs light up briefly). You may also reset the
board during operation through the DEBUG and RESET command in the
debugger. Both types of reset cause the DSP to reset to a known state. At
this point you should reload any programs you were working on.
Table 2-3 summarizes the types of resets.
Memory Checks
The monitor program performs some standard memory checks on Flash
memory and internal SRAM. The Flash memory test consists of verifying
a number in memory. If the monitor code is corrupted, the monitor may
crash before reaching the actual program code.
UART Check and Initialization
The software UART check is done when it attempts to connect to the
EZ-KIT Lite through a Transmitted Loop Back routine. This UART test
is performed by the host after the POST is complete. In this test, the host
sends the UART test protocol. This protocol specifies the number of bytes
that are transmitted to the EZ-KIT Lite board and instructs the board to
echo the byte stream back to the host. This test determines whether the
EZ-KIT Lite board is set to the correct baud rate and verifies the external
connections between the board and the host.

Fla s h c h ec k Yes No
AD73322 check Yes No
Initializations Yes Yes
ADSP-2189M EZ-KIT Lite Evaluation System Manual 2-7
Using EZ-KIT LITE Software
On power up, the EZ-KIT Lite board defaults to a baud rate of 57600
baud with 8 data bits, 1 stop bit, and no parity. To change this rate, wait
for the POST routine to complete and then use the Settings, Baud Rate
command in the VisualDSP++. Note that setting the baud rate to a lower
number can significantly slow the board’s re sponse to all debug activities.
Different baud rates depend upon your application’s type: for real-time
interrupt driven programs, a lower baud rate setting slows performance,
but the timer interrupt occurs less frequently. This gives your program a
larger share of the processor’s resources.
AD73322 Codec Check and Initialization
On reset, the AD73322 codec is inactive. An initialization routine initial-
izes the codec by sending a series of command words through the
SPORT0 TX interrupt. Once the commands have been sent and the
AD73322 initialized, it begins transmitting the clock, which synchronizes
data transfers to and from the DSP. Once this bit goes “High”, the
AD73322 is ready for standard communication over SPORT0.
Monitor Program Operations
The monitor program runs on the EZ-KIT Lite board as part of the DSP
executable and provides the ability to download, debug, and run user pro-
grams. The VisualDSP++ debugger is the interface for the monitor
program. Using the EZ-KIT Lite as a target with the debugger lets you
operate the board remotely.
There are three main components of the monitor program:
•“Halt loop”
•“UART ISR”
•“Command Processing”
Standard Operations
2-8 ADSP-2189M EZ-KIT Lite Evaluation System Manual
Halt loop
The monitor program idles in the halt loop when the program is not run-
ning user code. While there, you can READ and WRITE memory and
registers, download programs, set breakpoints, change the UART’s baud
rate, and single step through your code. To enter the halt loop from code,
you must suspend or stop the code, using either a breakpoint or a HALT
instruction. At this point, the halt loop polls the UART. With every char-
acter received from the UART, the command-processing kernel verifies
whether a full command has been received. If a full command has been
received, the kernel processes the command; otherwise, control is returned
to the halt loop to wait for more characters. The only method of executing
your code once the halt loop has been entered is to send a RUN or SINGLE
STEP command in the debugger.
UART ISR
The UART Interrupt Service Routine (Timer ISR) is entered when your
code is running, but the host is still interacting with the board. As the host
sends bytes, the UART ISR takes the data stream from the UART and
builds the command. As with the halt loop, each character received is
passed to the command-processing kernel. Unlike the halt loop, the mon-
itor returns to your code immediately after the interrupt is serviced.
#The following restrictions should be observed to ensure correct
board operation.
• The host loses contact with the monitor while the user program is
running if the user program disables the Timer interrupt or changes
the Timer interrupt vector.
ADSP-2189M EZ-KIT Lite Evaluation System Manual 2-9
Using EZ-KIT LITE Software
• The host loses contact with the monitor while the program is run-
ning and it enters an Interrupt Service Routine when nesting is
turned on.
• The host cannot halt with the debugger’s Debug, Halt command if
global IRQ enable is disabled; however, breakpoints will work.
Command Processing
Command processing, initiated from either the UART ISR or the Halt
loop, is done in the command-processing kernel. This kernel parses the
commands and executes the instructions. If the instruction requires data
to be sent back to the host, the kernel initiates the response.
Software Breakpoints
The ability to stop the execution of code and examine processor registers
and memory is extremely helpful when debugging code. Note that the
debugger automatically inserts breakpoints at the function main(), when
the Settings, Run To Main command is checked, and at the _exit
instruction.
AD73322 Codec Dual Analog Front End
The monitor does not initialize the AD73322 codec. This provides you
with greater flexibility to experiment with custom codec operations. Sim-
ple code examples, such as TalkThrough, are provided with your EZ-KIT
Lite to demonstrate some basic codec operations. It is recommended that
you model your code using these examples.
"Once the codec has been initialized, you must use a hard reset to
re-initialize it.
Standard Operations
2-10 ADSP-2189M EZ-KIT Lite Evaluation System Manual
For more information about the AD73322 codec, go to
http://www.analog.com/Analog_Root/productPage/productH-
ome/0,2121,AD73322,00.html.
AD73322 Codec Transmissions
After initialization, the AD73322 codec generates the clock used to trans-
fer data across SPORT0. The ADSP-2189M DSP initiates all transmissions
with the AD73322 device by sending a synchronization pulse. Even
though the AD73322 transmits the data clock, it may not be ready for
normal operation.
Initialization of the AD73322 codec is slightly different than that of other
codecs. Initialization is performed by sending at lest 8 and up to 16 con-
trol words contained in a circular buffer to the AD73322 codec. These
control words correspond to the AD73322s control registers
Athrough H.This is usually done via the SPORT0 TX interrupt routine.
Once the codec is initialized, normal operation mode is entered, and the
TX interrupt routine is never used again until the device is reset. During
normal operation, the RX interrupt of SPORT0 is used. As each datum is
received from the codec, an interrupt is generated. This interrupt is the
SPORT0 RX interrupt. Inside the RX interrupt, datum are moved from the
RX buffer into the users buffer (generally, this is a circular buffer). At that
same RX interrupt, the codec is ready to receive data from the DSP. The
DSP then moves the data (from the users circular buffer) into SPORT0s TX
buffer and clocks it into the codec.

Debugging With EZ-KIT Lite
The VisualDSP++ User’s Guide for 16-Bit Processors and online Help con-
tains most of the information you need to operate the VisualDSP++
debugger with the EZ-KIT Lite evaluation board. Because the manual was
written using a simulator as a target, there are some differences and restric-
tions in the debugger operation when co nnected to a hardware target.
Loading Programs
Because you are loading programs into a hardware target, the load process
takes a slightly longer period of time then loading in the simulator. Wait
for the Load Complete message in the Output window before you
attempt any debug activities.
To load a program, use the following procedure:
1. From the File menu, select Load.
The Open a Processor Program dialog box appears.
2. Navigate to the folder where your DSP executable file resides.
The demos supplied with the EZ-KIT Lite are located in the
..\218x\EZ-KITs\2189M\Examples subdirectory of your Visu-
alDSP++ installation directory.
3. Select the file and click Open.
The file loads and the Load Complete message appears in the Out-
put window when the load process has completed.
Registers and Memory
To see current values in registers and memory, use the F12 key or the
Window, Refresh command.
#Register and memory contents may not be changed while the user
program is running.
ADSP-2189M EZ-KIT Lite Evaluation System Manual 2-15
Using EZ-KIT LITE Software
Setting Breakpoints and Stepping
The debugger automatically inserts breakpoints at the function main(),
when the Settings, Run To Main command is checked, and at the _exit
instruction.
#Breakpoints set in the last three instructions of a do-loop are
allowed, but this causes improper debugger operation.
Resetting EZ-KIT Lite Board
The EZ-KIT Lite board can be reset with the push button, SW2, switch on
the board or with the Debug, Reset command in the debugger. After per-
forming a reset, reload any programs you were running. The Debug,
Restart command also resets the processor. The processor, however,
retains all debug information and memory contents.
The following sequence must be used when starting the debugger:
1. Start VisualDSP++ from the Windows Start menu.
The debugger starts and the Target message Hit Reset Button
appears.
2. Press the reset button. Wait approximately three se conds for the
LEDs (except the power LED) to go dark.
3. Click OK.
#Do not use the reset button while the debugger is open unless the
debugger requested to do so.

Using EZ-KIT LITE Software
TalkThrough
Demonstrates how to use a circular buffer, which spans five pages of the
ADSP-2198M’s DM overlay memory as input and then sends the data
back out to the Line Out of the AD73322 codec. This program is inter-
rupt intensive and performs best at a low baud rate (9600).
Timer
Demonstrates how to hook into the timer interrupt handler. The timer
interrupt generates a 1-second on/off pulse on the FL1 LED. The idea
behind the timer interrupt is that the monitor program sets a timer at
3 times the baud rate and expects to receive 10 bits
(3xBAUDx10=1second). When every counter has expired, the reset
FL1 is executed.
#You can not set breakpoints in the interrupt routine if using the
ADSP-2189M monitor program
The TPERIOD register contains the current period of the timer. It is set to 3
times the baud rate. The timer is used as a baud rate generator so the
smaller the period, the faster the interrupt will occur. It is not advisable to
change the TPERIOD register since this will change the monitors baud rate,
and communications is lost with the host.
"This interrupt will continue to be vectored to even after the pro-
gram has halted.

these major components is described in the following sections
Flash Memory
The flash memory provide up to 4M x 8 bits of program storage that can
be loaded by the ADSP-2189M when it is programmed to boot from the
BMS (Boot Memory Select) and Mode A, B, C, and D switches. After the
ADSP-2189M processor is reset, the BDMA feature is used to load the
first 32 words of program memory from the byte memory space. Program
execution is held off until all 32 words are loaded. You can change the
mode of operation using the toggles on the mode DIP switch (SW3).
Refer to the ADSP-218x DSP Hardware Reference and data sheet for more
information on the processor’s boot modes.

User LEDs
•LED1 LED is a green light emitting diode which is on whenever the
board has power.
•LED2 is an amber light emitting diode which is on whenever there is
data transmitted via the serial port.
•LED3 is an amber light emitting diode, which is “ON” whenever data
is received via the serial port.
•LED4 is an amber light emitting diode, which is controlled by the
FL1 output of the ADSP-2189M processor. Software can control
the state of this indicator by writing to an internal register.
•LED5 is a red light emitting diode which indicates whether RESET is
asserted.
Switches
• The SW1 switch is the interrupt push button switch. Pushing this
button causes the ADSP-2189M to receive an IRQE interrupt input.
The processor then executes the current IRQE interrupt handler
software if the interrupt is enable d and the IRQE interrupt vector is
in place. The interrupt switch output is de-bounced electronically
to prevent multiple interrupts due to mechanical contact bounce.
• The SW2 switch is the reset push button switch. Pushing this but-
ton causes the ADSP-2189M processor and the AD7322 codec to
enter the hardware reset state and remain there until it is released.
The switch outputs are de-bounced electronically to prevent multi-
ple transitions due to mechanical contact bounce.

AD73322 Codec Connectors
When the AD73322 codec is enabled on the EZ-KIT Lite board, you can
access the audio input and output jacks on the board. Each of the audio
connectors are stereo mini jacks and accept standard commercially avail-
able stereo mini plugs.
The Microphone/Line_in Input jack connects to the LINE_IN_L (left) and
LINE_IN_R (right) pins or the MIC1 and MIC2 of the AD73322 SoundPort
Stereo codec, depending on the setting of jumpers JP3.
The LINE Output jack connects to the left (L) LINE_OUT and right (R)
LINE_OUT pins of the code c.
EZ-ICE Connector
The ADSP-218x EZ-ICE Emulator aids the hardware debugging of an
ADSP-2189M system. The emulator consists of hardware, host computer
resident software, and the target board connector. The ADSP-2189M
integrates on-chip emulation support with a 14-pin ICE-Port interface

(Figure 3-4). This interface provides a simpler target board connection
that requires fewer mechanical clearance considerations than other
ADSP-2100 EZ-ICEs. The ADSP-2189M device need not be removed
from the target system when using the EZ-ICE, nor are any adapters
needed. Due to the small footprint of the EZ-ICE connector, emulation
can be supported in final board designs.
The EZ-ICE performs provides:
• In target operation
• Setting up to 30 breakpoints
• Single stepping or full speed operation
• Examining and altering registers and memory values
• Uploading and downloading PC functions
• Instruction-level emulation of program booting and execution
• Complete assembly and disassembly of instruct ions
• C source-level debugging
The EZ-ICE header is a 14-pin header with the connections shown in
Figure 3-4.

3-14 ADSP-2189M EZ-KIT Lite Evaluation System Manual
Designing EZ-ICE Compatible Systems
This section describes the ADSP-218x family EZ-ICE theory of operation
to aid your EZ-ICE compatible system designs.
When power is applied to the board, a reset circuit holds the processor in
RESET for approximately 200 ms. RESET is then de-asserted and the proces-
sor begins the boot process. The Mode A-D pins are set up by default to
boot the processor from the byte-wide memory interface, which is con-
nected to the Flash EPROM.
The hardware consists of a printed circuit board measuring 3.5 inches by
5.5 inches. Assembled onto the printed circuit board are: an
ADSP-2189M digital signal processor, a Flash EPROM, an AD73322
codec, and various support circuits and connectors. The board is a com-
plete signal processing system designed to demonstrate the capabilities of
the ADSP-2189M digital signal processor. It can also be used as a plat-
form to develop new applications targeting ADSP-2189M processors.
Figure 3-4. EZ-ICE 14-pin Header
ADSP-2189M EZ-KIT Lite Evaluation System Manual 3-15
EZ-KIT Lite Hardware Reference
The EZ-KIT Lite board is an example of a minimum implementation of
an ADSP-2189M processor. The Flash EPROM is connected to the pro-
cessor via the Byte DMA Port. This interface uses only eight of the
24 data lines to carry data (D8 through D15). Eight of the spare data lines
(D16 through D23) are used to provide additional address bits. This allows
the ADSP-2189M to address up to 32 Mbits (4 Mbytes) of memory. The
DSP is configured to boot from the Flash EPROM when RESET is
de-asserted or if power is applied to the board.
The AD73322 codec is connected to the DSP via SPORT0. This high speed
synchronous serial port carries all of the data, control, and status informa-
tion between the DSP and the codec. It is possible to disable the codec if
the serial port is to be used for another purpose. When the jumper (JP1) is
shorted, the codec is disabled and its signals are put in a high impedance
state.
The SPORT1 pins are used to communicate with the host PC via the
RS-232 interface (P8). The Flag In and Flag Out pins carry the receive
and transmit data. Software running on the DSP emulates a UART to
provide the proper protocol for asynchronous serial communications up to
a data rate of 115K bits per second.
Hardware Debugging
If the green LED fails to light, check your power connections. Verify that
your power supply has the proper size connector and that the polarity is
correct. The power supply voltage measured at the connector to the board
should be 8V to 10V DC. Also, make sure that there are no objects
beneath or on top of the board that may be causing a short circuit. Hit the
reset button (SW1) if the board appears to be operating improperly.

A RESTRICTIONS
The following restrictions apply to release 1.1 of the ADSP-2189M
EZ-KIT Lite evaluation board. For information on any ADSP-2189M sil-
icon anomalies, see the anomaly sheet that accompanied this product.
1. Breakpoints set in the last three instructions of a do-loop are
allowed but cause your code to run incorrectly.
2. The host loses contact with the monitor while the user program is
running if the user program disables the Timer interrupt or changes
the Timer interrupt vector.
3. The host loses contact with the monitor while the program is run-
ning and in an ISR when nesting is turned on.
4. Do not use the Reset button while the debugger is open unless the
debugger requests you to do so. This causes the debugger to stop
communicating.
5. Do not run more than one ADSP-2189M EZ-KIT Lite session in
the debugger at any one time. You may run an EZ-KIT Lite session
and a simulator or ICE session at the same time or you can open
two debugger interfaces to run more than one EZ-KIT Lite session.
