mode, the adc? serial data clock (sclk) and left/right select (l/r) word clock pins are outputs. the l/r word clock output is the opposite polarity of i 2 s. it is inverted in the programmable logic device (pld) to create true i 2 s. the adc receives its oversampling clock on the digital section clock input (iclkd), which is then internally divided by two, and this signal is provided to the analog section clock input (iclka). iclkd can be driven from the 11.2896 mhz clock, the 12.288 mhz clock, or the 256 f s clock produced by the cs8412 aes/ebu receiver. the audio power down input (apd) and digital power down input (dpd) pins are wired to the cntl_mute signal of the pld. when pulled high, the adc will be muted. when first pulled low, the adc will be reset, then it will be enabled. the other possible input source comes from the spdif inputs (j14 for electrical input and j17 for optical input). jumper jp4 selects the source (see table 2-1 below). when receiving valid spdif input, the spdif receiver drives the master clock (mck) output that is 256 times the frame sync frequency of the received data. the cs8412 operates in mode 3, the i 2 s slave mode. table 2-1 jp4 jumpers

provides a means for the user to select which clock controls the reception and transmission of digital audio (see table 2-2 below). jp2 selects the adc and dac clocks which, when jumpered, are set at 44.1 khz and, when not jumpered, at 48 khz. the expansion connector, j5, can be used to directly access the dsp. the receive sai bus may be clocked by the selection made at jp2 (44.1 khz or 48 khz) or be clocked by the received spdif signal. the transmit sai bus may be clocked by either the clock selected at jp2 or by the received spdif signal. it is the user? responsibility to ensure that data is output at the desired rate. see table 2-2 , below. table 2-2 jp5 jumpers 2.1.2 serial audio interface (sai) the dsp56009 sai transmitter drives the six analog outputs and the spdif output. i 2 s is the default mode for the dacs. the master clock (mclk) rate for the dacs is 256 f s . the dual rc networks after the dacs serve as ac couplers for audio data, optical spdif jp4.3 to jp4.5 jp4.4 to

waveforms. the digitally controlled analog domain attenuators receive the audio data and attenuate or amplify the data as determined by the microcontroller. the attenuators receive the serial clock input (sclk), serial data input (sdatai), and the chip select/latch (cs) from the microcontroller. 2.1.3 sony-philips digital interface format (spdif) the spdif transmitter receives data from the dsp through the serial data input (sdata) using the frame sync (fsync) and the serial data clock (sck). the transmitter outputs spdif audio signals through j15 (electrical) and j16 (optical). fs_sens from the clock select appears at the expansion connector in order to read the sampling rate with the dsp? general purpose i/o (gpio1) at j5.41 and also at u21-2 to select the state of the ?ample-rate?bits transmitted within the channel status block. see the spdif specification for more information. the channel status bits and block sync signals (drcv_blk, dtrn_blk, drcv_cs, and dtrn_cs) are available at j5.43 to allow the dsp to read one of them, as well. isolation transformers are used on both input and output, although they are not strictly required for spdif because this evaluation module is intended to be used as a development system. 2.1.4 other inputs and outputs the clock master is derived from one of two sources: the 11.2896 mhz clock or the 12.288 mhz clock. the microcontroller also receives commands from either the soft switches (s1, s2, s3, or s4) or from the keypad expansion port, j18. the current user screen or the results of these commands are then displayed by a modular lcd panel with a 2 16 character display. the microcontroller code is capable of driving larger lcd displays, but all user screens are designed for a 2 16 character display. the mc68hc711e9 communicates with the dsp via the serial host interface (shi) port in spi mode. when ss is pulled low, the microcontroller can write to the dsp. the mosi and miso lines pass control data through the dsp shi in 24-bit mode. sck is the spi shift clock from the dsp. again, the expansion connector, j5, can be used to access or intercept host port communications. 2-6 DSP56009EVMUM motorola evaluation module theory of operation inputs and outputs the control_data, control_clock, and control_latch lines from the microcontroller control the digitally controlled analog domain attenuators. the control_mute line mutes the adc and the dacs; low is muted, high is enabled. 2.1.5 operating mode selection dsp56009evm modes can be selected at jp3, as shown in table 2-3 . once the mode has been selected, the pld can receive interrupts from the network attached to j19. x = jumper installed; - = no jumper 2.1.6 once port the once tm port interface operates by receiving the serial data from the rs-232 transceiver and executing commands sent by the host computer. these commands can reset the dsp, put the dsp in debug mode, release the dsp from debug mode, read and write to the once tm port, and read and write to the dsp itself. the serial bit rate is 19,200 bits/second. the rs-232 serial communications are performed in software on the mc68705k1. port a of the mc68705k1 communicates with the dsp, and port b communicates with the host computer. the acknowledge signal from the once tm port is a low-going pulse on ds0. since the 68705k1 is too slow to reliably table 2-3 jp3 jumpers mode jp3.5 to

the pulse is latched in the pld and the output of the latch appears on the ack pin (pa2). when this occurs, the 68705k1 illuminates red led d5 to indicate that the dsp is in the debug mode. for more information on the once port, see the dsp56000 family manual. the reset switch will reset the microcontroller, which will subsequently reset the dsp56009. the mc68705k1 source and object code are available from the motorola dsp division; contact your local motorola fae. 2.1.7 rs232 connections and jp1 rs-232 is an often-abused standard, and the direction of the signals present on pins 2 and 3 of the db9 connector do not always conform to the standard. jp1 provides the user with the ability to reverse these two pin connections without resorting to null modem adapters or rewiring cable connectors. as shipped, jp1.1 is connected via shorting jumpers to jp1.3 and jp1.2 is connected to jp1.4. this connects j4.2 to the output of the evaluation module? rs-232 level converter (u4) and j4.3 to the input of the board? rs-232 receiver. these directions can be reversed by reorienting the shorting jumpers and turning them 90 degrees (one-quarter turn), thereby connecting jp1.1 to jp1.2 and jp1.3 to jp1.4. the user should never need to rewire an rs-232 connector in order to establish evaluation module communications with a host computer. 2.1.8 operating modes and sram refresh in the 56009 in modes 0, 1, 2, and 3 the sram is refreshed from the nvram and the dsp can bootstrap from the sram via the emi if a valid bootstrap mode is used. when in modes 4, 5, 6, and 7 the sram is not refreshed. refreshes are not affected by jumpers on the expansion connector, j5. jumpers j5.37 and j5.39 must be inserted to have full dsp control of the sram and nvram after bootstrap. 2.1.9 evaluation module parts the parts list of the dsp56009evm is shown in section 5 . 2-8 DSP56009EVMUM motorola evaluation module theory of operation inputs and outputs 2.1.10 power supplies the evaluation module requires power sources, for both analog and digital circuits, in order to operate. bipolar analog power (use a linear power supply for best results) is received through screw terminals at j3. digital power is received through screw terminals at j2 or via a 2.1mm connector (j1). when the power is on, d6 (green led) is illuminated. analog power input may be 8 to 12 volts and digital power input may be 8 to 15 volts. while the voltage regulator can accommodate higher input voltage potentials, the added heat dissipation required at these input voltage levels will result in the regulator becoming dangerously warm, and it is not recommended that the user subject the board to power inputs in excess of the maximum levels listed. note: always supply the evaluation module with analog power prior to or simultaneous with the application of digital power. if digital power is supplied before the analog power, the dacs may go into one of three possible error modes (no long-term damage to the device will occur), and will not function correctly. if analog power is supplied first, or if both analog power and digital power are applied simultaneously, these problems do not appear and the dacs are properly initialized. 2.1.11 memory the evaluation module has 8192 bytes each of fast static ram (sram) and of nonvolatile ram (nvram). the sram operates at zero wait states at a 40 mhz dsp clock speed, one wait state at 50, 66 mhz and two wait states at 81 mhz. the contents of the sram may be block-loaded into nvram and the contents of the nvram may be block- loaded into the sram. the lowest 3072 bytes of the nvram may also be used to store code to load into the dsp via emi bootstrap. motorola DSP56009EVMUM 3-1 section 3 peripheral specifications 3-2

peripheral devices is included along with the parts listing in section 5 . 3.1 cs5390 stereo adc the cs5390 is a complete analog-to-digital converter (adc) for stereo digital audio systems. it performs sampling, analog-to-digital conversion and anti-alias filtering, generating 20-bit values for both left and right inputs in serial form. the output word rate can be up to 50 khz per channel. the cs5390 uses fifth-order, delta-sigma modulation with 64 times oversampling followed by digital filtering and decimation, which removes the need for an external anti-alias filter, beyond the simple balanced rc filter formed by r25, r26, and c8 (r31, r32, and c20 for the right channel). the adc uses a differential architecture that provides excellent noise rejection. the cs5390 has a filter passband of dc to 21.7 khz. the filters are linear phase, have 0.005 db passband ripple, and greater than 100 db stopband rejection. the operating temperature range is 0 o to 70 o . figure 3-1 cs5390

resolution, including interpolation, 1-bit digital-to-analog conversion, and output analog filtering in an 8-pin package. the cs4331 is based on delta-sigma modulation where the modulator output controls the reference voltage input to an ultra-linear analog low-pass filter. this architecture allows for infinite adjustment of sample rate between 1 khz and 50 khz while maintaining linear phase response, simply by changing the master clock frequency. the cs4331 contains optional on-chip de-emphasis and operates from a single +5 v power supply. the cs4331 has a 96 db dynamic range, less than 0.003% thd, low clock jitter sensitivity and completely filtered line level outputs that use linear-phase filtering. . figure 3-2 cs4331 dac 3.3 cs3310 stereo digital volume control the cs3310 is a complete stereo digital volume control designed specifically for audio systems. it features a 16-bit serial interface that controls two independent, low distortion (0.001% thd + n) audio channels. the cs3310 includes an array of well-matched resistors and a low-noise active output stage that is capable of driving a 600 w load. a total adjustable range of 127 db, in 0.5 db steps, is achieved through

test program overview motorola DSP56009EVMUM 6-3 6.1 overview this section contains an example that illustrates how to develop a very simple program for the dsp56009. this example has been designed for users who have little or no experience with the dsp development tools. the example demonstrates the form of assembly programs, gives instructions on how to assemble programs, and shows how the debugger can be used to verify the operation of programs. the rounded blocks represent the assembly and object files. the white blocks represent software programs to assemble and link the assemble programs. the gray blocks represent hardware products. the following sections give basic information regarding the assembly program, the assembler, the linker and the object files. detailed information about these subjects can be found in the assembler and linker manuals provided with the motorola dsp clas software package, available through your motorola sales office or distributor. the documentation is also available through the motorola dsp internet url http://www.motorola-dsp.com . figure 6-1 development process flow assembly program assembler relocatable linker executable object

sections describe the format of assembly language source statements and give an example assembly program. 6.2.1 source statement format programs written in assembly language consist of a sequence of source statements. each source statement may include up to six fields separated by one or more spaces or tabs: a label field, an operation field, an operand field, up to two data transfer fields, and a comment field. for example, the following source statement shows all six possible fields: 6.2.1.1 label field the label field is the first field of a source statement and can take one of the following forms: a space or tab as the first character on a line ordinarily indicates that the label files is empty and that the line has no label. an alphabetic character as the first character indicates that the line contains a symbol called a label. an underscore as the first character indicated that the label is a local label. with the exception of some directives, a label is assigned the value of the location counter of the first word of the instruction or data being assembled. a line consisting of a label only is a valid line and has the effect of assigning the value of the location counter to the label. 6.2.1.2 operation field the operation field appears after the label field and must be preceded by at least one space or tab. entries in the operation field may be one of three types: opcode ?nemonics that correspond directly to dsp machine instructions directive ?pecial operation codes known to the assembler which control the assembly process trm mac x0,y0,a x:(r0)+,x0 y:(r4)+,y0 ;text l abel operation operand x data transfer y data transfer comment example test program writing the program motorola DSP56009EVMUM 6-5 macro call invocation of a previously defined macro which is to be inserted in place of the macro call 6.2.1.3 operand field the interpretation of the operand field is dependent on the contents of the operation field. the operand field, if present, must follow the operation field and must be preceded by at least one space or tab. 6.2.1.4 data transfer fields most opcodes can specify one or more data transfers to occur during the execution of the instruction. these data transfers are indicated by two addressing mode operands separated by a comma, with no embedded blanks. if two data transfers are specified, they must be separated by one or more blanks or tabs. refer to the dsp56000 family manual for a complete discussion of addressing modes that are applicable to data transfer specifications. 6.2.1.5 comment field comments are not considered significant to the assembler, but can be included in the source file for documentation purposes. a comment field is composed of any characters that are preceded by a semicolon. 6.2.2 example program this program takes two lists of data, one in x memory, and one in y memory, and calculates the sum of the products of the two lists. calculating the sum of products is the basis for many dsp functions. therefore, the dsp56009 has a special instruction (mac) that multiplies two values and adds the result to the contents of an accumulator. this program is provided as example.asm on the dsp56009evm demos diskette and is placed in the evm56007 directory by the installation procedure. 6-6 DSP56009EVMUM motorola example test program writing the program example 6-1

give a list of assembler special characters and directives, and give instructions to assemble the example program. 6.3.1 assembler command format the motorola dsp assembler is included with the dsp56009evm on the motorola 3-1/2 inch diskette and can be installed by following the instructions in section 1.4.3 . the motorola dsp assembler is a program that translates assembly language source statements into object programs compatible with the dsp56009. the general format of the command line to invoke the assembler is: asm56000[options] 6-8 DSP56009EVMUM motorola example test program assembling the program 6.3.2 assembler options -a this option indicates that the assembler should run in absolute mode, generating an absolute object file when the -b command line option is given. by default, the assembler produces a relocatable object file that is subsequently processed by the motorola dsp linker. -b example test program assembling the program motorola DSP56009EVMUM 6-9 optional pathname. the -ea option causes the standard error stream to be written to 6-10 DSP56009EVMUM motorola example test program assembling the program this example uses ibm pc pathname conventions, and would cause the assembler to prefix any include files not found in the current directory with the \project\ pathname. -l example test program assembling the program motorola DSP56009EVMUM 6-11 6.3.3 assembler directives in addition to the dsp56009 instruction set, the assembly programs can contain mnemonic directives that specify auxiliary actions to be performed by the assembler. these are the assembler directives. these directives are not always translated into machine language. the following sections briefly describe the various types of assembler directives. 6.3.3.1 assembler significant characters there are several one and two character sequences that are significant to the assembler. the assembler significant characters are: ; - comment delimiter ;; - unreported comment delimiter \ - line continuation character or macro dummy argument concatenation operator ? - macro value substitution operator % - macro hex value substitution operator ^ - macro local label override operator - macro string delimiter or quoted string define expansion character @ - function delimiter * - location counter substitution ++ - string concatenation operator [] - substring delimiter << - i/o short addressing mode force operator < - short addressing mode force operator > - long addressing mode force operator # - immediate addressing mode operator #< - immediate short addressing mode force operator #> - immediate long addressing mode force operator 6-12 DSP56009EVMUM motorola example test program assembling the program 6.3.3.2 assembly control the directives used for assembly control are: comment - start comment lines define - define substitution string end - end of source program fail - programmer generated error message force - set operand forcing mode himem - set high memory bounds include - include secondary file lomem - set low memory bounds mode - change relocation mode msg - programmer generated message org - initialize memory space and location counters radix - change input radix for constants rdirect - remove directive or mnemonic from table scsjmp - set structured control branching mode scsreg - reassign structured control statement registers undef - undefine define symbol warn - programmer generated warning example test program assembling the program motorola DSP56009EVMUM 6-13 6.3.3.3 symbol definition the directives used to control symbol definition are: endsec - end section equ - equate symbol to a value global - global section symbol declaration gset - set global symbol to a value local - local section symbol declaration section - start section set - set symbol to a value xdef - external section symbol definition xref - external section symbol reference 6.3.3.4 data definition/storage allocation the directives used to control constant data definition and storage allocation are: baddr - set buffer address bsb - block storage bit-reverse bsc - block storage of constant bsm - block storage modulo buffer - start buffer dc - define constant dcb - define constant byte ds - define storage dsm - define modulo storage dsr - define reverse carry storage endbuf - end buffer 6-14 DSP56009EVMUM motorola example test program assembling the program 6.3.3.5 listing control and options the directives used to control the output listing are: list - list the assembly lstcol - set listing field widths nolist - stop assembly listing opt - assembler options page - top of page/size page prctl - send control string to printer stitle - initialize program subtitle tabs - set listing tab stops title - initialize program title 6.3.3.6 object file control the directives used for control of the object file are: cobj - comment object code ident - object code identification record symobj - write symbol information to object file example test program assembling the program motorola DSP56009EVMUM 6-15 6.3.3.7 macros and conditional assembly the directives used for macros and conditional assembly are: dup - duplicate sequence of source lines dupa - duplicate sequence with arguments dupc - duplicate sequence with characters dupf - duplicate sequence in loop endif - end of conditional assembly endm - end of macro definition exitm - exit macro if - conditional assembly directive maclib - macro library macro - macro definition pmacro - purge macro definition 6.3.3.8 structured programming the directives used for structured programming are: .break - exit from structured loop construct .continue - continue next iteration of structured loop .else - perform following statements when .if false .endf - end of .for loop .endi - end of .if condition .endl - end of hardware loop .endw - end of .while loop .for - begin .for loop .if - begin .if condition .loop - begin hardware loop .repeat - begin .repeat loop .until - end of .repeat loop .while - begin .while loop 6-16 DSP56009EVMUM motorola example test program motorola dsp linker 6.3.4 assembling the example program the assembler is a ms-dos based program, thus to use the assembler you will need to exit windows or open a ms-dos prompt window. to assemble the example program, type asm56000 -a -b -l -g example.asm in the evm007 directory created by the installation process from section 1.4.3 . this will create two additional files: example.cld and example.lst. the example.cld file is the absolute object file of the program, and this is what will be downloaded into the dsp56009. the example.lst file is the listing file and gives full details of where the program and data will be placed in the dsp56009 memory. 6.4 motorola dsp linker though not needed for our simple example, the motorola dsp linker is also discussed here in the dsp56009evm user? manual. the dsp linker may be obtained through your motorola sales office or distributor. the motorola dsp linker is a program that processes relocatable object files produced by the motorola dsp assembler, generating an absolute executable file that can be downloaded to the dsp56009. the general format of the command line to invoke the linker is: dsplnk [options] example test program motorola dsp linker motorola DSP56009EVMUM 6-17 6.4.1 linker options -a this option auto-aligns circular buffers. any modulo or reverse-carry buffers defined in the object file input sections are relocated independently in order to optimize placement in memory. code and data surrounding the buffer are packed to fill the space formerly occupied by the buffer and any corresponding alignment gaps. example: dsplnk -a myprog.cln this example links the file myprog.cln and optimally aligns any buffers encountered in the input. -b 6-18 DSP56009EVMUM motorola example test program motorola dsp linker this example redirects the standard error output to the file errors. if the file already exists, it will be overwritten. -f example test program motorola dsp linker motorola DSP56009EVMUM 6-19 -l 6-20 DSP56009EVMUM motorola example test program motorola dsp linker in this example, the files filter.cln, fft.cln, and fio.cln are linked to produce the absolute executable file filetr.cld. all symbol references are mapped to lower case. -o |
