QUICK START A PC with an ECP parallel port, a stereo analog audio source, and powered speakers are required to use the CRD42528 in the mode specified in this Quick Start. 1) Install the drivers supplied with the board on the PC. Refer to “UDSP Schematics” on page 37 for details on installing the drivers. 2) Connect the supplied parallel port cable to J46 on the UDSP MainBoard (marked P PORT) and to the computer’s ECP parallel port. 3) Connect the analog output from an audio source to AIO7-8 (Left and Right Inputs) The input channels are mapped as follows: - AIO8 - Left - AIO7 - Right - AIO6 - Left Surround - AIO5 - Right Surround - AIO4 - Center - AIO3 - Subwoofer / Low Frequency Effects (LFE) - AIO2 - Surround Back Left - AIO1 - Surround Back Right 4) Connect powered speakers to AIO15-16. The output channels are mapped as follows (more speakers can be connected to the line level outputs as required by each application): - AIO16 - Left - AIO15 - Right - AIO14 - Left Surround - AIO13 - Right Surround - AIO12 - Center - AIO11 - Subwoofer or Low Frequency Effects (LFE) - AIO10 - Surround Back Left or Lt - AIO9 - Surround Back Right or Rt 5) Connect the supplied power supply to the power connector on the board and to an appropriate power outlet. 6) Verify that LEDs D1, D7, D9, and D11 on the UDSP board are lit. LED D2 will flash to indicate that the PLD on the UDSP is functional. 7) Open a DOS window and navigate to the C:\CS49300\CRD42528\Configs directory. 8) Type in “setpld -r 99” on the DOS prompt. (This reads the PLD version register and verifies that the PC can communicate with the board). If the driver generates the error message “!!! Board does not appear to be connected !!!”, then your parallel port address may not be 0x378 or your port is not ECP capable. If your parallel port address is not 0x378, depress the reset switch S3 and type in “setpld -r 99 -p3bc” or “setpld -r 99 -p278” to communicate using a different parallel port address. 9) Verify that LED D1 (marked ERR) has turned OFF, indicating that the driver has successfully communicated with the board. 10) If the above steps give an error, refer to “UDSP Schematics” on page 37 and verify that the drivers and PC have been set up as described (and that the parallel port address is correct / set to ECP mode). 11) If the above steps give the expected results, ty p e in “an alo g _ in_ 9 6 kH z”, “an alo g _in_ 9 6k H z p 3b c”, or “analog_in_96kHz -p278” (depending on your parallel port address) at the DOS prompt. This batch file will configure the PLD, boot the DSP, and configure the CS42528 for 8 channel analog processing at 96 kHz. 12) The audio data on the Left and Right Input connectors (AIO7-8) should now be heard on the output. 13) The batch files use various files to configure the software, board, and the DSP code. Each batch 5 file has been commented. Various batch files for the commonly used applications have been supplied with the software. These batch files can be run from the DOS prompt like the “analog_in_96kHz.bat” file. Please note that while only license-free code is supplied with the CRD42528, a complete list of algorithms supported by the CRD42528 (including Dolby 6 Digital EX and DTS-ES) is available from your local Cirrus Logic, Inc. Field Applications Engineer. Caution:Use caution while editing and making changes to these files (editing a copy will always insure an easily accessible backup). It is strongly recommended that jumpers and switches on the UDSP MainBoard be left in their default positions. 2. DESIGN DESCRIPTION 2.1 Clock and Data Connections There are 2 main modes of operation of the CRD42528, Analog Input Mode and Digital Input Mode. In Analog Input Mode, up to 8 channels of analog input can be processed by the DSP. In Digital Input Mode, S/PDIF (IEC61937/IEC60958) data is sent to the DSP for decoding or processing. In both cases, the output from the DSP is sent back to the CS42528 to generate analog output. 2.1.1 Analog Input Mode A detailed diagram of the clock and data connections for analog input mode can be found in Figure 4, “Data and Clock Connections for 8 Channel Analog Input and Output,” on page 10. When Analog Input Mode is used, the CRD42528 will process up to 8 channels of analog input. The analog source is the analog I/O connectors on the UDSP MainBoard, which are routed directly to the CRD42528. The Left (L) and Right (R) analog inputs are connected, via input filters, to the CS42528’s analog input pins. When 6 channel (referred to as 5.1 channel) input is desired, two external CS5351 Analog to Digital Converters are used. These external ADCs receive the RMCK output from the CS42528. In this mode, RMCK will pass through the 12.288 MHz oscillator connected to OMCK. The external ADC serial ports are driven from the CS42528’s CX port clocks. The Left Surround (Ls), Right Surround (Rs), Center (C), and Subwoofer (Sub) inputs to the CRD42528 are connected to the external CS5351’s analog inputs, and the digital outputs from the two external CS5351s is then connected to the CS42528’s ADCIN1/2 pins. The CS42528 will incorporate all of the data from the external ADCs and it’s own analog input data onto a single line and send it to the DSP via the CS42528’s SAI port. In this way, the DSP gets the L, R, Ls, Rs, C, and Sub channels into it’s CDI port. For 7 or 8 channel (6.1 or 7.1 channel) operation, another external CS5351 is used to convert the Surround Back Left (SBL) and Surround Back Right (SBR) analog inputs. Please note that many appli- cations use a single mono surround channel, referred to as Surround Back (SB). The digital output from the CS5351 is sent directly to the DSP’s DAI port. Once the DSP has processed the incoming digital inputs, data is returned to the CS42528 to be converted back to analog. The data, coming from the DSP’s DAO port, is clocked by the CS42528’s CX port clocks. 2.1.2 Digital Input Mode A detailed diagram of the clock and data connections for analog input mode can be found in Figure 5, “Clock and Data Connections for S/PDIF (IEC61937 / IEC60958) Input,” on page 11. To process incoming S/PDIF (IEC61937/IEC60958) data streams, digital input is wired directly from the UDSP’s optical receivers to the CS42528. The CS42528 will then lock to the incoming stream and convert it to an I2S data stream, which is then sent to the DSP from the CS42528’s SAI port. This data is input on the DSP’s CDI port. The DSP will process this stream (i.e., decode the compressed stream or process the PCM data), and then send up to 8 channels of I2S data to the CS42528 on it’s DAO port. This PCM data is input on the CS42528’s CX port. The CS42528 then converts the audio data back to analog. 2.2 Control Control of the CRD42528 is done via the UDSP headers (J2 and J3) in either SPI or I2C mode. Different resistors must be populated or not populated according to the desired communication mode. These options can be found in Table 1. For I2C mode, please note that the DSP defaults to address checking disabled. This can only be changed after a firmware image has been loaded onto the DSP (either via host boot or autoboot). Please see the CS49300 datasheet for more details on I2C address checking. 7 Mode SPI I2C Do Not Populate Populate R98, R99, R10, R12, R16, R143 R13, R14, R18, R100, R144,R168, R166 R13, R14, R18, R100, R144,R168, R166 R98, R99, R10, R12, R16, R143 Table 1. Communication Mode Options 2.3 Assembly Options for Ease of Manufacture There are variety of options available on a build of the CRD42528 that allow for different input and output options, as well as performance differentiation. This allows the same board to be used in both low-end and high-end applications. Please note that systems with lower performance may require external analog Bass Management circuitry to comply with Dolby specifications. 2.3.1 Analog Input Options The CRD42528 supports 2, 6, or 8 channels of analog input. A list of components that needs to be populated for each configuration is shown in Table 2.

Analog Output Assembly Options 8 2.3.3 Memory Options There are many available applications that can run on the CS49300 family DSP. DSP applications require a 32k-byte page in an external ROM, Flash, or other non-volatile storage. Some applications, called Internal Boot Assisted (IBA) codes, consist of a few hundred bytes of download firmware. When using IBA codes ONLY, the external Flash or ROM may be omitted from the design IF AND ONLY IF the IBA codes are stored in the host microcontroller’s available non-volatile memory. In these applications, U24 and C132 may be omitted. For a full AAC 5.1 discrete channels of output, external SRAM must be used. For all other applications, the SRAM U16 and support component C133 may be omitted. Other options exist for AAC multichannel, including a stereo downmixed AAC output following by Dolby ProLogic II processor, which generates 5.1 channels of output. For a full list of codes (including IBA codes) and their requirements, please contact your local Cirrus Field Applications Engineer. as shown in Figure 2 should be modified as shown in Figure 3.

The Direct Hardware version will communicate directly with the PC’s parallel port to control the UDSP board. The DLPortIO version uses the DLPortIO driver to access the parallel port on hardware protected operating systems. In general, direct hardware capable operating systems (such as Microsoft® Windows 95®, Windows 98®, and Windows ME®) allow any program to directly control any of the PC’s peripherals. With the UDSP board, this allows for faster interface speeds (up to 4 times faster). For protected operating systems (such as Microsoft® Windows NT®, Windows 2000®, and Windows XP®), the UDSP driver set requires the use of the DLPortIO driver. This utility allows the UDSP drivers to access the parallel port safely. The UDSP driver set requires bidirectional communication with the UDSP board, and hence a bidirectional capable parallel port is needed. An ECP-type port is required. Please note that an SPPtype port will not work with the UDSP board. The type and location (I/O address) of the parallel port installed can be found in the Windows Control Panel (please see Windows Help for more information on these settings). The UDSP drivers assume by default that the parallel port address is 0x378. Other ports may be used with the -pXXX option, where XXX is 3bc or 278. 12 Installation on Microsoft® Windows 95®, 98®, ME® and other direct hardware capable Windows® versions 1.

These software tools are designed to so that they can be scripted using the MS-DOS batch language. They will work with any of the 3 standard parallel port addresses (0x378, 0x3bc, 0x278). The default address for all of the programs is 0x378 (typically LPT1). The port address can be changed by using the '-p' option. Each time a program is executed, the address that was used can be shown on the screen using the ‘-v’ option. If a program seems to fail, verificatio n o f th e p arallel po rt ad dress sh ou ld alw ay s be the first step in trou blesho otin g. All of these programs are designed to access the daughter card connected to the UDSP board using SPI or I2C® serial communication. The communication mode can be chosen from the command line with the '-m' option. The mode chosen must correspond to the communication mode used by the devices on the daughter card. If the device on the board is set up for one communication mode, and the drivers are used with another, results will be unpredictable. All devices on the daughter card are configured for SPI serial communication mode by default, and that is also the default mode for the software. The usage of each program will vary, depending on the type of UDSP daughter card that is installed. The URST, URD, and UCMD programs get a valid list of devices for the installed daughter card from the file specified by the “uINI_path” DOS environment variable. This file will list all of the devices available to the UDSP parallel port drivers, along with each device’s I 2C address, SPI address, chip select number, and reset number (for reset capable devices). It also specifies how messages from the device should be read. For DSP-style reads, the driver will read until the INTREQ line goes high. For non-DSP devices, the read operation will read out 1 byte. Please note that most non-DSP devices require an aborted write operation to properly set the MAP pointer before reading. The device list file, called CRD42528.INI, must follow a very specific format. An example of this can be found “CRD42528.INI” on page 13. This file should not be changed. A list of available drivers and their usage is found below: UCMD.exe - Send commands or configuration files to a target device. Usage: ucmd <[ABCDEF..] or [-fX]> [-dZZZZ..] [-mY] [-pWWW] [-v] -d = device ZZZZ.. = device designator, eg dspab, dspc, 8415a, etc. -m = communication mode Y = mode designator (i=I2C, s=SPI*, m=MOT, n=INT) ABCDEF.. = hex data (1-100 bytes) -f = send configuration file X = .cfg file containing configuration parameters -p = parallel port address WWW = address in hex (278, 378* or 3bc) -v = enable verbose mode * = default value Example: ucmd 000001 -d4341 -p3bc Notes: A configuration file is a list of commands, contained in an ASCII text file. This file can be any length, and should list the commands in hex, with an even number of characters per line. Comments can be made in the file by putting a # at the beginning of the line.

If a DSP-type device is selected and the INTREQ pin is not low when URD.exe is executed, the program will wait until INTREQ drops. Press the ‘Enter’ key to exit the read wait loop. Usage: urd [-dZZZZ..] [-mY] [-pXXX] [-v] [-h] -d = device ZZZZ = device designator, eg dspab, dspc, 8415a, etc. -m = communication mode Y = mode designator (i=I2C, s=SPI*, m=MOT, n=INT) -p = parallel port address XXX = address in hex (278, 378* or 3bc) -v = enable verbose mode -h = this message * = default value EXAMPLE: urd -d4940c -p378 Notes: If the associated INTREQ pin is not low when URD is executed, the program will wait until INTREQ drops for DSP devices ONLY. Press the ‘Enter’ key to exit the program in this case. URST.exe - Program used to perform hard reset or soft reset on the target device. Usage: urst [-dZZZZ..] [-mY] [-s] [-pXXX] [-v] [-h] -d = device ZZZZ = device designator, eg dspab, dspc, 8415a -m = communication mode Y = mode designator (i = I2C, s = SPI*, n = INTEL, m = MOTOROLA) -s = Soft Reset -p = parallel port address XXX = address in hex (278, 378* or 3bc) -v = enable verbose mode -h = this message * = default value SetPLD.exe - Program used to read and write PLD registers. Usage: setpld -r/-w RR [DD] Where -r is to read from register RR, -w is to write data DD into register RR. RR and DD are in hex. 15 16 APPENDIX D: SCHEMATICS Figure 6. Control and Data I/O Figure 7.
