Memory Map u Two types of External Memory n SDRAM u 64 Mbytes (#2 M x 16 -bits) u Processor’s memory select pin (~SMS 0) is configured for the SDRAM n Flash Memory u Implemented with dual-bank flash memory devices. u Primary and Secondary flash memory as well as internal SRAM and registers. n Primary Flash Memory n 2 Mbytes mapped into two separate asynchronous memory banks of 1 Mbyte each. n Secondary Flash Memory + SRAM and Memory Mapped Registers u Occupies the third bank of asynchronous memory space. u Processor’s ~AMS 0, ~AMS 1, and ~AMS 2 memory select pins are used for that purpose. 05 November 2020 Veton Këpuska 16

SRAM Interface u Three SDRAM control registers must be initialized in order to use the MT 48 LC 32 M 16 – 64 MB (32 M x 16 bits) SDRAM memory. u SDRAM registers after reset are set automatically to default (optimal) values (see listed values in Table of ADSP-BF 533 EX-Kit Lite Evaluation System Manual). n To set other values Use Target Options dialog box of the Setting pull-down menu. 05 November 2020 Veton Këpuska 17

Flash Memory u Flash memory usage requires configuration of such devices. u The ADSP-BF 533 EZ-KIT Lite board employs two PSD 4256 G 6 V flash general-purpose IO devices. u Example code is provided in the EZ-Kit installation directory to demonstrate how to program the flash memory. 05 November 2020 Veton Këpuska 18

LEDs and Push Buttons u EZ-KIT Lite provides: n four push buttons and n six LEDs for general- purpose IO. u LEDs: n The six LEDs, labeled LED 4 through LED 9, are accessed via some of the general-purpose IO pins of the flash memory interface. n For information on how to program the pins, see “Flash General-Purpose IO” on page 1 -12 of EZKit Lite Manual. 05 November 2020 Veton Këpuska 19

LEDs and Push Buttons u Push Buttons n The four general-purpose push button are labeled SW 4 through SW 7. n A status of each individual button can be read through programmable flag (PF) inputs, PF 8 through PF 11. u A PF reads 1 when a corresponding switch is being pressed-on. When the switch is released, the PF reads 0. u A connection between the push button and PF input is established through the SW 9 DIP switch. See “Push Button Enable Switch (SW 9)” on page 2 -12 of the Manual for details. n An example program is included in the EZ-KIT installation directory to demonstrate the functionality of the LEDs and push buttons. 05 November 2020 Veton Këpuska 20

Audio Interface u 3 channel of stereo audio output u 2 channel of multi-channel of audio input is provided by AD 1836 audio codec u Input sample rate of 96 or 48 k. Hz u SPORT 0 interface of the processor links with the stereo audio data input and output pins of the AD 1836 codec. u Processor is capable of transferring data to the audio codec in: n TDM – Time division multiplexed or u Operates at a maximum of 48 k. Hz sample rate but allows simultaneous use of all input and output channels n TWI – Twin Wire Interface mode u The TWI mode allows the codec to operate at a 96 k. Hz sample rate but limits the output channels to two. 05 November 2020 Veton Këpuska 21

Audio Interface u When using TWI mode, the TSCLK 0 and RSCLK 0 pins, as well as the TFS 0 and RFS 0 pins of the processor, must be tied together external to the processor. u This is accomplished with the SW 9 DIP switch (see “Push Button Enable Switch (SW 9)” on page 2 -12 for more in ADSP-BF 533 EZ-KIT Lite Evaluation System Manual 05 November 2020 Veton Këpuska 22

Audio Interface Cofiguration u The AD 1836 audio codec’s internal configuration registers are configured using the SPI port of the processor. The processor’s PF 4 programmable flag pin is used as the select for this device. For information on how to configure the multichannel codec, go to www. analog. com/Uploaded. Files/Datasheets/344740003 AD 1 836_prc. pdf. u The general-purpose IO pin PA 0 of flash A is a source for the AD 1836 codec reset. See “Flash General-Purpose IO” on page 1 -12 of the Manual for more information about the pin. u Example programs are included in the EZ-KIT installation directory to demonstrate AD 1836 codec capabilities. 05 November 2020 Veton Këpuska 23

Video Interface u The board supports video input and output via ADV 7171 encoder and ADV 7183 decoder. u Both encoder and decoder connect to the parallel peripheral interface (PPI) of the processor. u For additional information on video interface hardware, refer to “PPI interface” on page 2 -5 of the ADSP-BF 533 EZ-KIT Lite Evaluation System Manual 05 November 2020 Veton Këpuska 24

Video Interface Set-Up 1. Configure the SW 3 DIP switch as required by the application. Refer to “Video Configuration Switch (SW 3)” on page 2 -11 of the ADSP-BF 533 EZ-KIT Lite Evaluation System Manual for details. 2. Remove reset to the video device. Refer to “Flash General-Purpose IO” on page 1 -12 ADSP-BF 533 EZ-KIT Lite Evaluation System Manual for details. 3. If using the decoder: u u Enable device by driving programmable flag output PF 2 to 0. Select PPI clock (see Table 1 -7 on page 1 -13). 4. Program internal registers of the video device in use. Both video encoder and decoder use a two-wire serial interface to access internal registers. A programmable flag PF 0 functions as a serial clock (SCL), and PF 1 functions as a serial data (SDAT). 5. Program the processor’s PPI interface (configuration registers, DMA, etc. ). 05 November 2020 Veton Këpuska 25

Example Programs u Example programs are provided with the ADSP-BF 533 EZ-KIT Lite to demonstrate various capabilities of the evaluation board. These programs are installed with the EZKIT Lite software and can be found in the …BlackfinExamplesADSP-BF 533 EZ-KIT Lite subdirectory of the Visual. DSP++ installation directory. Please refer to the readme file provided with each example for more information. 05 November 2020 Veton Këpuska 26
