Using ADSP-21489 EZ-Board 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.
EZ-Board Session Startup 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.
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.
Evaluation License Restrictions 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.
Using ADSP-21489 EZ-Board (SPI) flash, and parallel flash. See Table 1-2. For more information about a specific memory type, go to the respective section in this chapter. Table 1-1.
SDRAM Interface 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.
Using ADSP-21489 EZ-Board 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.
SPI Interface SPI Interface The ADSP-21489 processor has two SPI ports, which can be accessed via the digital peripheral interface (DPI) pins.
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.
S/PDIF Interface an LED (LED11) for a visual alarm if the temp exceeds the limit. The thermal limit flag and ADM1032 IRQ connect to the flag pins of the processor, but are nonessential for temperature monitoring. Consequently, the SW13 switch positions that control the flag pins are OFF by default. See “DPI [1–8] Enable Switch (SW3)” on page 2-9 and “External Port Enable Switch (SW13)” on page 2-12 for more information.
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.
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.
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.

JTAG Interface The JTAG connector (P1) allows the standalone debug agent module to connect a VisualDSP++ debug session to the ADSP-21489 processor.
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.
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.
Power-On-Self Test 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).
