33 Figure - Target Options.5 Using the Flag Pins The ADSP-6N has asynchronous Flags I/O pins. 0 of these pins (FLAG0-9) are available to let you interact with the running program. After the DSP is reset, the flags are configured as inputs. The directions of the flags are configured though the MODE register and are set and read though the FLAGS register. For more information on configuring the flag pins, see the ADSP-6N DSP Hardware Reference. Flags and their uses are described in Table -. Table -: Flag Pin Summary Flag Connected Use to FLAG0 SW FLAG0- are connected to the push buttons to supply FLAG SW feedback for program execution. For instance, you FLAG SW can write your code to trigger a flag when a routine is FLAG SW complete. FLAG- FLAG9 LED- LED7 FLAG-9 are connected to LEDs on the EZ-KIT Lite board and are for user output. FLAG0 & Not Connected Not Available! Note: FLAG0 FLAG are available on connector P0. ADSP-6N EZ-KIT Lite Evaluation System Manual -

34 .6 Using the Interrupt Pins The ADSP-6N has interrupt pins (IRQ0-) that let you interact with the running program. Each of the three external interrupts are directly accessible through the push button switches SW5 - SW7 on the EZ-KIT Lite board.. For more information on configuring the interrupt pins, see the ADSP-6N DSP Hardware Reference. Interrupts and their uses are described in Table -. Table -: Interrupt Pin Summary Interrupt Connected Use to IRQ0 SW5 IRQ0- are connected to the push buttons and supply IRQ SW6 feedback for program execution. For instance, you IRQ SW7 can write your code to trigger a flag when a routine is complete.! Note: IRQ0 IRQ are available on connector P0..7 Using the Audio Interface The audio interface on the EZ-KIT Lite board allows you to interface to the codec and digital receiver through various connectors. See section.5. for more information about the connectors. The audio interface consists of three main ICs, an AD86, AD85 and a CS8. The AD86 multi-channel codec features six digital-to-analog converters (DACs) and four analog-to-digital converters (ADCs), support multiple digital stereo channels with -bit conversion resolution and a 96 khz sample rate. The AD86 features a 08 d dynamic range for each of its six DACs, and a 0 d dynamic range for its four ADCs. The AD85 is a complete 8/0/-bit single-chip stereo digital audio playback system. It is comprised of a multibit sigma-delta modulator, digital interpolation filters, and analog output drive circuitry. Other features include an on-chip stereo attenuator and mute, programmed through an SPI-compatible serial control port. The AD85 is fully compatible with all known DVD formats including 9kHz and 96kHz sample frequencies and -bits. It also is backwards compatible by supporting 50/5µs digital de-emphasis intended for "redbook" Compact Discs, as well as de-emphasis at khz and 8kHz sample rate. The CS8 is a monolithic CMOS device that receives and decodes audio data up to 96kHz according to the AES/EU, IEC958, S/PDIF, and EIAJ CP0/0 interface standards. The CS8 receives data from a transmission line, recovers the clock and synchronization signals, and de-multiplexes the audio and digital data. The CS8 is setup to operate in I S compatible mode.

35 The Microphone and Line-In jacks connect to the left and right ADC channel on the AD86, depending on the setting of jumpers. See sections..9 and..8 for more information about configuring the jumpers. Two RCA jacks connect to ADC on the AD86. This input is configured though the input mode selection jumpers see section..7 for more information. The Line-Out jacks connect to the left and right DAC outputs of the AD86 and AD85. The CS8 has an error flag (VERF) that is used to indicate that the audio output may not be valid. This signal is connected to an LED (LED9) on the board. This signal may also be used by interpolation filters to provide error correction..8 Example Programs Example programs are provided with the ADSP-6N EZ-KIT Lite to demonstrate various capabilities of the evaluation board. These programs are installed with the EZ-KIT Lite software and can be found in \ \VisualDSP\xx\EZ-KITs\ADSP-6N\Examples. Please refer to the example program readme files for more information..9 Using the Flash Programmer Utility The ADSP-6N EZ-KIT Lite evaluation system includes a flash programmer utility. The utility allows you to program the flash on the EZ-KIT Lite. This utility must be installed separately from the debug software. To install the utility, insert the EZ-KIT Lite CD-ROM and follow the steps in the installation wizard.

37 . System Architecture The EZ-KIT Lite has been designed to demonstrate the capabilities of the ADSP- 6N DSP. This section will describe the DSP s configuration on the EZ-KIT Lite board. Figure -: System Architecture The DSP core voltage is.8v and the external interface operates at.v. A.5MHz through-hole oscillator supplies the input clock to the DSP. Footprints are provided on the board for a surface-mount oscillator and a throughhole crystal for alternate user installed clocks. The speed at which the core operates is determined by the location of the Clock Mode jumpers (JP). (See section...) y default, the DSP core runs at 00MHz.

38 .. External Port The external port is connected to a 5K x 8-bit flash memory. This memory is connected to the boot memory select (~MS) pin and the memory select (~MS) pin, allowing the flash memory to be used to boot the DSP as well as store information during normal operation. Refer to section. for information about the location of the flash memory in the DSP s memory map. The external memory interface is also connected to M x 8-bit SDRAM memory. This memory is connected to the memory select 0 (~MS0) pin. Refer to section.. for information about configuring the width of the SDRAM. Refer to section. for information about the location of the flash memory in the DSP s memory map. Some of the address, data, and control signals are available externally via two offboard connectors. The pinout of the EP connectors (P9 and P0) can be found in APPENDIX : SCHEMATIC... Host Processor Interface (HPI) The Host Port Interface (HPI) signals are brought to an unpopulated off board connector P9. This allows the HPI to interface to a user application. The pinout of the host port connector (P9) can be found in APPENDIX : SCHEMATIC... SPORT0 and SPORT Audio Interface SPORT0 and SPORT are connected to the AD86 codec (U0). A.5mm stereo jack and four RCA mono jacks allow audio to be input. A.5mm stereo jack and eight RCA mono jacks allow audio to be output. The codec contains two input channels. One channel is connected to a.5mm stereo jack and two RCA jacks. The.5mm stereo jack can be connected to a microphone. The two RCA jacks can be connected to a line out from an audio device. You can supply an audio input to the codec microphone input channel (MIC) or to the LINE_IN input channel. The jumper settings of JP determine the codec channel driven by the input jack (P)...
