Regulatory Compliance

The ADSP-21489 EZ-Board is designed to be used solely in a laboratory environment. The board is not intended for use as a consumer end product or as a portion of a consumer end product. The board is an open system design which does not include a shielded enclosure and therefore may cause interference to other electrical devices in close proximity. This board should not be used in or near any medical equipment or RF devices.

The ADSP-21489 EZ-Board is currently being processed for certification that it complies with the essential requirements of the European EMC directive 89/336/EEC amended by 93/68/EEC and therefore carries the “CE” mark.

The EZ-Board evaluation system contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the human body and equipment and can discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Store unused EZ-Boards in the protective shipping package.

Devices, Inc. evaluation system for SHARC® processors.

SHARC processors are based on a 32-bit super Harvard architecture that includes a unique memory architecture comprised of two large on-chip, dual-ported SRAM blocks coupled with a sophisticated IO processor, which gives a SHARC processor the bandwidth for sustained high-speed computations. SHARC processors represents today’s de facto standard for floating-point processing, targeted toward premium audio applications.

The evaluation board is designed to be used in conjunction with the Visu-

alDSP++® development environment to test the capabilities of the ADSP-21489 SHARC processors. The VisualDSP++ development environment aids advanced application code development and debug, such as:

• Create, compile, assemble, and link application programs written in C++, C, and assembly

• Load, run, step, halt, and set breakpoints in application programs

• Read and write data and program memory

• Read and write core and peripheral registers

• Plot memory

Access to the processor from a personal computer (PC) is achieved through a USB port or an external JTAG emulator. The USB interface of the standalone debug agent gives unrestricted access to the processor and evaluation board’s peripherals. Analog Devices JTAG emulators offer

EZ-Board Installation

For correct operation, install the software in the order presented in the VisualDSP++ Installation Quick Reference Card. Substitute instructions in step 3 with instructions in this section.

There are two options to connect the EZ-Board hardware to a personal computer (PC) running VisualDSP++ 5.0: via an Analog Devices emulator or via a standalone debug agent module. The standalone debug agent allows a debug agent to interface to the ADSP-21489 EZ-Board. The standalone debug agent is shipped with the kit.

To connect the EZ-Board to a PC via an emulator:

1. Plug the 5V adaptor into connector P16 (labeled 5.0V).

2. Attach the emulator header to connector P1 (labeled JTAG) on the back side of the EZ-Board.

To connect the EZ-Board to a PC via a standalone debug agent:

ADSP-21489 EZ-Board Evaluation System Manual 1-5

The debug agent can be used only when power is supplied from the wall adaptor.

1. Attach the standalone debug agent to connectors P1 (labeled JTAG) and ZP1 on the backside of the EZ-Board, watching for the keying pin of

2. Plug the 5V adaptor into connector

3. Plug one side of the provided USB cable into a USB connector of the standalone debug agent. Plug the other side of the cable into a USB port of the PC running VisualDSP++ 5.0 update 8 or later.

EZ-Board Session Startup

1. If you are running VisualDSP++ for the first time, navigate to the

VisualDSP++ environment via the Start–>Programs menu. The main window appears. Note that VisualDSP++ is not connected to any session. Skip the rest of this step to step 2.

If you have run VisualDSP++ previously, the last opened session appears on the screen. You can override the default behavior and force VisualDSP++ to start a new session by pressing and holding down the Ctrl key while starting VisualDSP++. Do not release the Ctrl key until the Session Wizard appears on the screen. Go to step 3.

2. To connect to a new EZ-Board session, start Session Wizard by

selecting one of the following.

• From the Session menu, New Session.

• From the Session menu, Session List. Then click New Ses-

sion from the Session List dialog box.

• From the Session menu, Connect to Target.

3. The Select Processor page of the wizard appears on the screen. Ensure SHARC is selected in Processor family. In Choose a target processor, select ADSP-21489. Click Next.

4. The Select Connection Type page of the wizard appears on the screen. For standalone debug agent connections, select EZ-KIT Lite and click Next. For emulator connections, select Emulator and click Next.

5. The Select Platform page of the wizard appears on the screen. For standalone debug agent connections, ensure that the selected platform is ADSP-21489 EZ-KIT Lite via Debug Agent. For emulator connections, choose the type of emulator that is connected.

1-6 ADSP-21489 EZ-Board Evaluation System Manual

Using ADSP-21489 EZ-Board

Specify your own Session name for the session or accept the default name.

The session name can be a string of any length; although, the box displays approximately 32 characters. The session name can include space characters. If you do not specify a session name, VisualDSP++ creates a session name by combining the name of the selected platform with the selected processor. The only way to change a session name later is to delete the session and open a new session.

Click Next.

6. The Finish page of the wizard appears on the screen. The page dis-

plays your selections. Check the selections. If you are not satisfied, click Back to make changes; otherwise, click Finish. VisualDSP++ creates the new session and connects to the EZ-Board. Once connected, the main window’s title is changed to include the session name set in step 5.

ADSP-21489 EZ-Board Evaluation System Manual 1-7

To disconnect from a session, click the disconnect button or select Session–>Disconnect from Target.

To delete a session, select Session –> Session List. Select the session name from the list and click Delete. Click OK.

Evaluation License Restrictions

The ADSP-21489 EZ-Board installation is part of the VisualDSP++ 5.0 update 8. The EZ-Board is a licensed product that offers an unrestricted evaluation license for the first 90 days. Once the initial unrestricted 90-day evaluation license expires:

• VisualDSP++ restricts a connection to the ADSP-21489 EZ-Board via the USB port of the standalone debug agent interface only. Connections to simulators and emulation products are no longer allowed.

• The linker restricts a user program to 27306 PM words for code space with no restrictions for data space.

• The EZ-Board hardware must be connected and powered up to use VisualDSP++ with a valid evaluation or permanent license.

Refer to the VisualDSP++ Installation Quick Reference Card for details.

Memory Map

The ADSP-21489 processor has internal static random access memory (SRAM) for instructions and data storage. See Table 1-1. The internal memory details can be found in the ADSP-214xx SHARC Processor Hard-

ware Reference.

The EZ-Board includes three types of external memory: synchronous dynamic random access memory (SDRAM), serial peripheral interconnect

SDRAM Interface

The ADSP-21489 processor connects to a 32 MB Micron MT48LC16M16A2P-6A chip through the SDRAM controller. The SDRAM memory controller on the processor and SDRAM memory chip are powered by the on-board 3.3V regulator. The SDRAM controller and memory on the EZ-Board can operate at a maximum clock frequency of 166 MHz.

With a VisualDSP++ session running and connected to the EZ-Board via the USB standalone debug agent, the SDRAM registers are configured automatically each time the processor is reset. The values are used whenever SDRAM is accessed through the debugger (for example, when viewing memory windows or loading a program).

To disable the automatic setting of SDRAM registers, select Target

Options from the Settings menu in VisualDSP++ and uncheck Use XML reset values. For more information on changing reset values, refer to the

online Help.

An example program is included in the EZ-Board installation directory to demonstrate how to setup and access the SDRAM interface. For more information on how to initialize the registers after a reset, search the VisualDSP++ online Help for “reset values”.

SRAM Interface

The board has a 1M x 16-bit flash memory connected to the processor’s AMI (asynchronous memory interface). The SRAM can be accessed via the asynchronous memory select 3 pin. It allows access to 16 bits of data and interfaces to address line 0 through 19 of the processor.

An example program is included in the EZ-Board installation directory to demonstrate how to setup and access the SRAM interface. For more infor-

mation on how to initialize the registers after a reset, search the VisualDSP++ online Help for “reset values”.

Parallel Flash Memory Interface

The parallel flash memory interface of the ADSP-21489 EZ-Board contains a 4 MB (4M x 8 bits) Numonyx M29W320EB chip. Flash memory is connected to the 8-bit data bus and address lines 0 through 21. Chip enable is decoded by the MS1 select line (default) through switch SW13 position 2. See “External Port Enable Switch (SW13)” on page 2-12. The address range for flash memory is 0x0400 0000 to 0x043F FFFF.

Flash memory is pre-loaded with boot code for the power-on-self test (POST) program. For more information, refer to “Power-On-Self Test”

on page 1-22.

By default, the EZ-Board boots from the 8-bit parallel flash memory. The processor boots from flash memory if the boot mode select switch (SW4) is set to position 2; see “Boot Mode Select Switch (SW4)” on page 2-10.

Flash memory code can be modified. For instructions, refer to the online Help and example program included in the EZ-Board installation directory.

For more information about the parallel flash device, refer to the Numonyx Web site:

ADSP-21489 EZ-Board Evaluation System Manual 1-11

http://www.numonyx.com.

SPI Interface

The ADSP-21489 processor has two SPI ports, which can be accessed via the digital peripheral interface (DPI) pins.

The SPI flash memory, a 16 Mb ST M25P16 device, connects to the SPI port of the processor and designates:

• DPI pin 5 (DPI_P5) as a chip select

• DPI pin 3 (DPI_P3) as the SPI clock

• DPI pin 1 (DPI_P1) as the master out slave in (MOSI) pin

• DPI pin 2 (DPI_P2) as the master in slave out (MISO) pin

The same SPI port and DPI pins are connected to the serial flash memory and audio codec via switch SW3. See “DPI [1–8] Enable Switch (SW3)” on

page 2-9. The DPI pins also are available on the expansion interface II.

By default, the EZ-Board boots from the 8-bit flash parallel memory. SPI flash can be selected as the boot source by setting the boot mode select switch (SW4) to position 1. See “Boot Mode Select Switch (SW4)” on

page 2-10.

The audio codec is set up to use DPI pin 4 as the SPI chip select. For more information, refer to “Audio Interface” on page 1-15.

Watch Dog Timer Interface

The ADSP-21489 processor includes a 32-bit watch dog timer (WDT) that can be used to implement a software watch dog function. A software watch dog can improve system reliability by forcing the processor to a known state through generation of a system reset if the timer expires before being reloaded by software. Software initializes the count value of the timer and then enables the timer.

1-12 ADSP-21489 EZ-Board Evaluation System Manual

Using ADSP-21489 EZ-Board

The watch dog timer resets both the core and internal peripherals. After an external reset, the WDT must be disabled by default. Software must be able to determine if the watch dog has been the source of the hardware reset by interrogating a status bit in the watch dog timer control register.

Be default, the watch timer interface is turned off. In order to use the feature, a user needs to turn switch

SW13 position 8 ON. SW13 connects the

watch dog reset out pin to the ADM708 system reset circuit. See “External

Port Enable Switch (SW13)” on page 2-12. Special attention must be paid

to this function because it can cause the processor and EZ-Board to remain in a permanent reset.

Example programs are included in the EZ-Board installation directory to demonstrate watch dog timer functionality.

Temperature Sensor Interface

Two external pins (THD_P and THD_M) of the processor are connected to an internal thermal diode. The EZ-Board uses ON Semiconductor’s ADM1032 digital thermometer and under/over temperature alarm to monitor the processor’s temperature as well as the thermal diode’s (inside

the ADM1032 device). The thermometer uses the I2C bus, DPI pins, and flag pins of the processor. The following DPI and flag pins are used for temperature monitoring.

• DPI pin 8 (

• DPI pin 7 (

DPI_P8) as the serial clock signal (SCK)

DPI_P7) as the serial data signal (SDA)

• Flag 0 as the IRQ (not used by default)

• Flag 3 as the thermal limit (not used by default)

The two DPI pins are required: the pins are connected to the temperature sensing monitor via a switch (

SW3) and can be shut off if the pins are used

on the expansion II interface. The thermal limit flag is connected to

S/PDIF Interface

The ADSP-21489 processor has a built-in S/PDIF transmitter and receiver for digital audio applications. The EZ-Board supports the S/PDIF interface and brings out both the transmitter and receiver via RCA connectors J6 and J7, respectively. The S/PDIF’s in and out pins are connected by DAI pins via switches SW1 and SW7:

• DAI pin 1 (DAI_P1) as SPDIF_OUT

• DAI pin 18 (DPI_P18) as SPDIF_IN

SW1

and SW7 can be turned OFF to disconnect the DAI pins from the RCA connectors if the pins are used on the expansion II interface. See “DAI [1–

8] Enable Switch (SW1)” on page 2-8 and “DAI [17–20] Enable Switch (SW7)” on page 2-11 for more information.

1-14 ADSP-21489 EZ-Board Evaluation System Manual

Using ADSP-21489 EZ-Board

Audio Interface

The AD1939 device is a high-performance, single-chip codec featuring eight digital-to-analog converters (DACs) for audio output and four analog-to-digital converters (ADCs) for audio input. This translates to four stereo channels of audio out and two stereo channels of audio in. The codec can input and output data at a sample rate of up to 192 kHz on all channels.

The analog audio channels are available via single-ended RCA connectors (J4 and J5) or differential DB25 connectors (P8 and P9). By default, the EZ-Board is shipped with the RCA connectors used by the AD1939 codec for audio in and out. To use the differential connectors, change DIP switches SW15–18. A standard, off the shelf DB25 connector to XLR cables is required to operate in this mode.

For more information, see “Audio In1 Left Selection Switch (SW15)” on

page 2-14 through “Audio In2 Left Selection Switch (SW18)” on page 2-16, and “ADSP-21489 EZ-Board Schematic” on page B-1.

The processor interfaces with the codec via DAI and DPI pins. The DAI pins can be configured to transfer serial data from the codec in Time-Divi-

sion Multiplexing (TDM) or Integrated Interchip Sound (I2S) mode. See

“DAI Interface” on page 2-3 for more information about the AD1939

connection to the DAI. The DPI interface pins can be configured to use the SPI interface of the processor to set up the codec’s control registers. See “DPI Interface” on page 2-4 for more information about the AD1939 connection to the DPI.

The master input clock (MCLK) of the codec is generated by the on-board

12.288 MHz oscillator. The internal PLL of the codec is used to generate varying sample rates. The codec can be set up for 48 KHz, 96 KHz, or 192 KHz frequencies. The codec can run at these frequencies in both

TDM and I

ADSP-21489 EZ-Board Evaluation System Manual 1-15

S modes with all ADCs inputs and DACs outputs. To run

Audio Interface

192 KHz with all ADCs and DACs in TDM mode, the codec must run in dual-line TDM mode.

For information on how to configure the multi-channel codec, refer to the product datasheet at:

http://www.analog.com/en/audiovideo-products/audio-codecs/ad1939/products/product.html

The EZ-Board is connected to the AD1939 codec in master mode. The internal PLL drives the ABCLK and ALRCLK clock signals out. Both clocks are driven back to the codec’s DBCLK and DLRCLK pins via the R257 and R258 resistors. The ABCLK and ALRCLK clocks that are driven by the codec also connect to the processor’s serial ports via the DAI pins. Resistors R262 and

R263 are used to feed the bit clock and frame sync signals of the processor’s

serial ports. Connecting the codec in this manner enables a flexible audio sample rate and allows the processor to run at the maximum core frequency.

The audio interface also has a 3.5 mm connector (J8) for headphones. The headphones share the output with the external DAC5 and DAC6 circuits of the analog audio interface. Switch SW23 must be enabled for the headphones. A volume control potentiometer (R493) is used to increase or decrease the headphone’s volume. For more information, see “Headphone

Enable Switch (SW23)” on page 2-18.

Example programs are included in the EZ-Board installation directory to demonstrate how to configure and use the board’s analog audio interface.

The DAI and DPI pins going to the AD1939 device can be disabled, then used again on the expansion II interface. Refer to “DAI Interface” on

page 2-3 and “DPI Interface” on page 2-4 for more information about the

DAI and DPI switches.

Using ADSP-21489 EZ-Board

UART Interface

The ADSP-21489 processor features a built-in universal asynchronous receiver and transmitter (UART). The UART interface supports full RS-232 functionality via the Analog Devices 3.3V ADM3202 line driver and receiver (U8). The UART signals are available on the EZ-Board via a DIP switch (SW14). The UART signals routed through the DIP switch can be disconnected from the respective DPI interface and used on the expansion II interface. The following DPI pins are used for the RS-232 interface.

• DPI pin 9 (DPI_P9) as UART_TX

• DPI pin 10 (DPI_P10) as UART_RX

• DPI pin 11 (DPI_P11) as UART_RTS

• DPI pin 12 (DPI_P12) as UART_CTS

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 LED connected to the temperature sensing monitor (ADM1032), 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

Two 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 and LEDs are connected to the processor through DIP switches. The DIP switches can disconnect the processor pins, which in turn are connected to the push buttons and LEDs. See the respective switch section in “ADSP-21489 EZ-Board Hardware Reference” on page 2-1.

The state of the push buttons connected to the flag pins can be determined 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 1-3 shows the push button and processor connections.

JTAG Interface

The JTAG connector (P1) allows the standalone debug agent module to connect a VisualDSP++ debug session to the ADSP-21489 processor. The debug agent operates only when the external 5V wall adaptor (P16) is used.

The standalone debug agent can be replaced by an external emulator, such as the Analog Devices high-performance USB-based emulator. Be careful not to damage the connectors when removing the debug agent. The emulator is connected to P1 on the back side of the board. See “EZ-Board

Installation” on page 1-5 for more information.

The ADSP-21489 EZ-Board can be set up as a single- or multi-processor system. By default, the board is set up in single-processor mode. In single-processor mode, create a VisualDSP++ session based on a standalone debug agent or an external emulator. To use the EZ-Board in multi-processor mode, install an external emulator. Only one external emulator is required for the main EZ-Board; other EZ-Boards in the JTAG chain do not require an emulator. In this mode, create a VisualDSP++ platform based on the number of JTAG devices in the JTAG chain using the VisualDSP++ Configurator. Then create a session in VisualDSP++ based on the newly created platform.

ADSP-21489 EZ-Board Evaluation System Manual 1-19

Expansion Interface II

For a dual ADSP-21489 EZ-Board session, connect two EZ-Boards via connectors

J3 and P12. Flip one of the two EZ-Boards by 180 degrees to

allow the boards to mate. To switch between single- and multi-processor modes, use DIP switches SW19–22. For more information, see “JTAG

Switches (SW19–22)” on page 2-16.

For three or more ADSP-21489 EZ-Board sessions, connect each of the EZ-Board with JTAG cables. The cables connect JTAG pins of each EZ-Board. By using the cables, you put the EZ-Board in a JTAG serial chain. For three EZ-Boards, three JTAG cables are required. Similarly, for four EZ-Boards, four JTAG cables are required. Note that each respective EZ-board also requires its own power supply.

Part numbers for Samtec standard, off the shelf link port cables can be found in “MP JTAG Out Connector (P12)” on page 2-28.

Expansion Interface II

The expansion interface II allows an Analog Devices EZ-Extender or a custom-design daughter board to be tested across various hardware platforms with identical expansion interfaces.

The expansion interface II implemented on the ADSP-21489 EZ-Board consists of two connectors: a 0.1 in. shrouded header ( QMS series header (

J1). The connectors contain a majority of the

ADSP-21489 processor’s signals.

For pinout information, go to “ADSP-21489 EZ-Board Schematic” on

Using ADSP-21489 EZ-Board

For more information about daughter boards, visit the Analog Devices Web site at:

http://www.analog.com/en/embedded-processing-dsp/sharc/content/sharc_development_tools/fca.html

Limits to current and interface speed must be taken into consideration when using the expansion interface II. Current for the expansion interface II is sourced from the EZ-Board; therefore, the current should be limited to 1A for 5V and 500 mA for the 3.3V planes. If more current is required, then a separate power connector and a regulator must be designed on a daughter card. Additional circuitry can add extra loading to signals, decreasing their maximum effective speed.

Analog Devices does not support and is not responsible for the effects of additional circuitry.

Power Measurements

Several locations are provided for measuring the current draw from various power planes. Precision 0.05 ohm shunt resistors are available on the VDDINT and VDDEXT voltage domains. For current draw measurements, the associated jumper on connectors P14—15 must be removed. Once the jumper is removed, voltage across the resistor can be measured using an oscilloscope. Once voltage is measured, current can be calculated by dividing voltage by 0.05. For the highest accuracy, a differential probe should be used for measuring voltage across the resistor.

For more information, see “VDDINT Power Connector (P14)” on

page 2-28 and “VDDEXT Power Connector (P15)” on page 2-29.

ADSP-21489 EZ-Board Evaluation System Manual 1-21

Power-On-Self Test

The power-on-self-test program (POST) tests all EZ-Board peripherals and validates functionality as well as connectivity to the processor. Once assembled, each EZ-Board is fully tested for an extended period of time with a POST. All EZ-Boards are shipped with the POST preloaded into one of their on-board flash memories. The POST is executed by resetting the board and pressing the proper push button(s). The POST also can be used for reference in custom software designs or hardware troubleshooting. Note that the source code for the POST program is included in the VisualDSP++ installation directory along with the readme text file, which describes how the board is configured to run a POST.

Example Programs

Example programs are provided with the ADSP-21489 EZ-Board to demonstrate various capabilities of the product. The programs are installed with the VisualDSP++ software and can be found in the

<install_path>\214xx\Examples\ADSP-21489 EZ-Board directory. Refer

to the readme file provided with each example for more information.

Background Telemetry Channel

The USB debug agent supports the background telemetry channel (BTC), which facilitates data exchange between VisualDSP++ and the processor without interrupting processor execution.

The BTC allows you to read and write data in real time while the processor continues to execute. For increased performance of the BTC, including faster reading and writing, please check our latest line of processor emulators at:

Push Buttons and Switches

Programmable Flag Push Buttons (SW8–11)

Four momentary push buttons (SW8–11) are provided for general-purpose user input. The buttons are connected to the GPIO pins of the processor. The push buttons are active high and, when pressed, send a high (1) to the processor. Switches SW7 and SW13 disconnect the push buttons from the responding signals. Refer to “DAI [17–20] Enable Switch (SW7)” on

page 2-11 and “External Port Enable Switch (SW13)” on page 2-12 for

more information.

Reset Push Button (SW12)

The reset push button (SW12) resets the following ICs:

• ADSP-21489 processor (U1)

• AD1939 audio codec (U45)

• Parallel flash memory (U18)

The reset also is linked to the expansion II interface; any daughter card connected to the expansion interface that requires a reset can use SW12.

The reset push button does not reset the standalone debug agent once the debug agent is connected to a personal computer (PC). After communication between the debug agent and PC is initialized, pushing a reset button does not reset the USB chip on the debug agent. The only way to reset the USB chip on the debug agent is to power down the EZ-Board.

External Port Enable Switch (SW13)

The external port enable switch (SW13) disconnects the control pins of the processor from the associated peripherals on the EZ-Board and allows the

ADSP-21489 EZ-Board Evaluation System Manual 2-19

Jumpers

Flash WP Jumper (JP1)

The flash WP jumper (JP1) write-protects block 0 of the parallel flash chip. Block 0 is located at address range 0x0400 0000–0x0400 1FFF. The POST begins at block 0 and continues on to other blocks in flash memory. When the jumper is installed on JP1, and the parallel flash driver from Analog Devices is used, block 0 is read-only. By default, JP1 is not installed.

S/PDIF Loopback Jumper (JP2)

The S/PDIF loop back jumper (JP2) is used for internal testing only. The jumper loops back any digital audio signal from the S/PDIF’s Data Out pin to the S/PDIF’s Data In pin. By default, JP2 is not installed.

UART RTS/CTS Jumper (JP3)

The UART RTS/CTS jumper (JP3) connects the RTS and CTS pins of the RS-232 interface. By default, JP3 is installed.

UART Loopback Jumper (JP4)

The UART loop back jumper (JP4) is used for internal testing only. The jumper loops back UART receive data from UART transmit data. By default,

JP4 is not installed.

DSP Audio Oscillator Jumper (JP5)

The processor audio oscillator jumper (JP5) connects a 24.576 MHz oscillator to the control of the serial port signals connected to the AD1939 audio codec via the oscillator. The jumper can be used to make the processor the master and the AD1939 device—the slave. By default, JP5 is not installed, resulting in the AD1939 being the master, and the processor being the slave.
