Blackfin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISClike microprocessor instruction set, and single instruction, mul tiple data (SIMD) multimedia capabilities into a single instruction set architecture. The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are completely code and pin-compatible, differing only with respect to their performance and on-chip memory. Specific perfor mance and memory configurations are shown in Table 1. Table 1. Processor Comparison ADSP-BF531 ADSP-BF532 ADSP-BF533 power consumption. Varying the voltage and frequency can result in a substantial reduction in power consumption, com pared with just varying the frequency of operation. This translates into longer battery life for portable appliances. SYSTEM INTEGRATION The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are highly integrated system-on-a-chip solutions for the next gener ation of digital communication and consumer multimedia applications. By combining industry-standard interfaces with a high performance signal processing core, users can develop cost-effective solutions quickly without the need for costly external components. The system peripherals include a UART port, an SPI port, two serial ports (SPORTs), four general-pur pose timers (three with PWM capability), a real-time clock, a watchdog timer, and a parallel peripheral interface.

The generalpurpose peripherals include functions such as UART, timers with PWM (pulse-width modulation) and pulse measurement capability, general-purpose I/O pins, a real-time clock, and a watchdog timer. This set of functions satisfies a wide variety of typical system support needs and is augmented by the system expansion capabilities of the part. In addition to these generalpurpose peripherals, the ADSP-BF531/ADSP-BF532/ ADSP-BF533 processors contain high speed serial and parallel ports for interfacing to a variety of audio, video, and modem codec functions; an interrupt controller for flexible manage ment of interrupts from the on-chip peripherals or external sources; and power management control functions to tailor the performance and power characteristics of the processor and sys tem to many application scenarios. All of the peripherals, except for general-purpose I/O, real-time clock, and timers, are supported by a flexible DMA structure. There is also a separate memory DMA channel dedicated to data transfers between the processor's various memory spaces, including external SDRAM and asynchronous memory. Multi ple on-chip buses running at up to 133 MHz provide enough bandwidth to keep the processor core running along with activ ity on all of the on-chip and external peripherals. The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors include an on-chip voltage regulator in support of the proces sor's dynamic power management capability. The voltage regulator provides a range of core voltage levels from a single 2.25 V to 3.6 V input. The voltage regulator can be bypassed at the user's discretion. 2 1 1 3 1 1 1 16 16K bytes 16K bytes 16K bytes 4K bytes 1K bytes 2 1 1 3 1 1 1 16 16K bytes 32K bytes 32K bytes 2 1 1 3 1 1 1 16 16K bytes 64K bytes 32K bytes 32K bytes 4K bytes 4K bytes 1K bytes 1K bytes 400 MHz 400 MHz 600 MHz 160-Ball 160-Ball 160-Ball 169-Ball 169-Ball 169-Ball 176-Lead 176-Lead 176-Lead By integrating a rich set of industry-leading system peripherals and memory, Blackfin processors are the platform of choice for next generation applications that require RISC-like program mability, multimedia support, and leading-edge signal processing in one integrated package. PORTABLE LOW POWER ARCHITECTURE Blackfin processors provide world-class power management and performance. Blackfin processors are designed in a low power and low voltage design methodology and feature dynamic power management--the ability to vary both the volt age and frequency of operation to significantly lower overall Rev. E | Page 3 of 60 | July 2007 ADSP-BF531/ADSP-BF532/ADSP-BF533 BLACKFIN PROCESSOR CORE As shown in Figure 2 on Page 5, the Blackfin processor core contains two 16-bit multipliers, two 40-bit accumulators, two 40-bit ALUs, four video ALUs, and a 40-bit shifter. The compu tation units process 8-bit, 16-bit, or 32-bit data from the register file. The compute register file contains eight 32-bit registers. When performing compute operations on 16-bit operand data, the register file operates as 16 independent 16-bit registers. All operands for compute operations come from the multiported register file and instruction constant fields. Each MAC can perform a 16-bit by 16-bit multiply in each cycle, accumulating the results into the 40-bit accumulators. Signed and unsigned formats, rounding, and saturation are supported. The ALUs perform a traditional set of arithmetic and logical operations on 16-bit or 32-bit data. In addition, many special instructions are included to accelerate various signal processing tasks. These include bit operations such as field extract and population count, modulo 232 multiply, divide primitives, satu ration and rounding, and sign/exponent detection. The set of video instructions includes byte alignment and packing opera tions, 16-bit and 8-bit adds with clipping, 8-bit average operations, and 8-bit subtract/absolute value/accumulate (SAA) operations. Also provided are the compare/select and vector search instructions. For certain instructions, two 16-bit ALU operations can be per formed simultaneously on register pairs (a 16-bit high half and 16-bit low half of a compute register). Quad 16-bit operations are possible using the second ALU. The 40-bit shifter can perform shifts and rotates and is used to support normalization, field extract, and field deposit instructions. The program sequencer controls the flow of instruction execu tion, including instruction alignment and decoding. For program flow control, the sequencer supports PC relative and indirect conditional jumps (with static branch prediction), and subroutine calls. Hardware is provided to support zero-over head looping. The architecture is fully interlocked, meaning that the programmer need not manage the pipeline when executing instructions with data dependencies. The address arithmetic unit provides two addresses for simulta neous dual fetches from memory. It contains a multiported register file consisting of four sets of 32-bit index, modify, length, and base registers (for circular buffering), and eight additional 32-bit pointer registers (for C-style indexed stack manipulation). Blackfin processors support a modified Harvard architecture in combination with a hierarchical memory structure. Level 1 (L1) memories are those that typically operate at the full processor speed with little or no latency. At the L1 level, the instruction memory holds instructions only. The two data memories hold data, and a dedicated scratchpad data memory stores stack and local variable information. In addition, multiple L1 memory blocks are provided, offering a configurable mix of SRAM and cache. The memory manage ment unit (MMU) provides memory protection for individual tasks that may be operating on the core and can protect system registers from unintended access. The architecture provides three modes of operation: user mode, supervisor mode, and emulation mode. User mode has restricted access to certain system resources, thus providing a protected software environment, while supervisor mode has unrestricted access to the system and core resources. The Blackfin processor instruction set has been optimized so that 16-bit opcodes represent the most frequently used instruc tions, resulting in excellent compiled code density. Complex DSP instructions are encoded into 32-bit opcodes, representing fully featured multifunction instructions. Blackfin processors support a limited multi-issue capability, where a 32-bit instruc tion can be issued in parallel with two 16-bit instructions, allowing the programmer to use many of the core resources in a single instruction cycle. The Blackfin processor assembly language uses an algebraic syn tax for ease of coding and readability. The architecture has been optimized for use in conjunction with the C/C++ compiler, resulting in fast and efficient software implementations. MEMORY ARCHITECTURE The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors view memory as a single unified 4G byte address space, using 32-bit addresses. All resources, including internal memory, external memory, and I/O control registers, occupy separate sections of this common address space. The memory portions of this address space are arranged in a hierarchical structure to provide a good cost/performance balance of some very fast, low latency on-chip memory as cache or SRAM, and larger, lower cost and performance off-chip memory systems. See Figure 4 on Page 6, Figure 5 on Page 6, and Figure 3 on Page 6. The L1 memory system is the primary highest performance memory available to the Blackfin processor. The off-chip mem ory system, accessed through the external bus interface unit (EBIU), provides expansion with SDRAM, flash memory, and SRAM, optionally accessing up to 132M bytes of physical memory. The memory DMA controller provides high bandwidth datamovement capability. It can perform block transfers of code or data between the internal memory and the external memory spaces. Internal (On-Chip) Memory The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor has three blocks of on-chip memory providing high bandwidth access to the core. The first is the L1 instruction memory, consisting of up to 80K bytes SRAM, of which 16K bytes can be configured as a four way set-associative cache. This memory is accessed at full processor speed.

Blackfin Processor Core The second on-chip memory block is the L1 data memory, con sisting of one or two banks of up to 32K bytes. The memory banks are configurable, offering both cache and SRAM func tionality. This memory block is accessed at full processor speed. The third memory block is a 4K byte scratchpad SRAM which runs at the same speed as the L1 memories, but is only accessible as data SRAM and cannot be configured as cache memory. 1M byte segment regardless of the size of the devices used, so that these banks will only be contiguous if each is fully popu lated with 1M byte of memory. I/O Memory Space Blackfin processors do not define a separate I/O space. All resources are mapped through the flat 32-bit address space. On-chip I/O devices have their control registers mapped into memory mapped registers (MMRs) at addresses near the top of the 4G byte address space. These are separated into two smaller blocks, one containing the control MMRs for all core functions, and the other containing the registers needed for setup and con trol of the on-chip peripherals outside of the core. The MMRs are accessible only in supervisor mode and appear as reserved space to on-chip peripherals. External (Off-Chip) Memory External memory is accessed via the external bus interface unit (EBIU). This 16-bit interface provides a glueless connection to a bank of synchronous DRAM (SDRAM) as well as up to four banks of asynchronous memory devices including flash, EPROM, ROM, SRAM, and memory mapped I/O devices. The PC133-compliant SDRAM controller can be programmed to interface to up to 128M bytes of SDRAM. The SDRAM con troller allows one row to be open for each internal SDRAM bank, for up to four internal SDRAM banks, improving overall system performance. The asynchronous memory controller can be programmed to control up to four banks of devices with very flexible timing parameters for a wide variety of devices. Each bank occupies a Booting The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor con tains a small boot kernel, which configures the appropriate peripheral for booting. If the ADSP-BF531/ADSP-BF532/ ADSP-BF533 processor is configured to boot from boot ROM memory space, the processor starts executing from the on-chip boot ROM. For more information, see Booting Modes on Page 14. Rev.

ADSP-BF533 Internal/External Memory Map Event Handling The event controller on the ADSP-BF531/ADSP-BF532/ ADSP-BF533 processor handles all asynchronous and synchro nous events to the processor. The ADSP-BF531/ADSP-BF532/ ADSP-BF533 processor provides event handling that supports both nesting and prioritization. Nesting allows multiple event service routines to be active simultaneously. Prioritization ensures that servicing of a higher priority event takes prece dence over servicing of a lower priority event. The controller provides support for five different types of events: * Emulation - An emulation event causes the processor to enter emulation mode, allowing command and control of the processor via the JTAG interface. * Reset - This event resets the processor. * Nonmaskable Interrupt (NMI) - The NMI event can be generated by the software watchdog timer or by the NMI input signal to the processor. The NMI event is frequently used as a power-down indicator to initiate an orderly shut down of the system. * Exceptions - Events that occur synchronously to program flow (i.e., the exception will be taken before the instruction is allowed to complete). Conditions such as data alignment violations and undefined instructions cause exceptions. * Interrupts - Events that occur asynchronously to program flow. They are caused by input pins, timers, and other peripherals, as well as by an explicit software instruction. 0xFFB0 0000 RESERVED Figure 4. ADSP-BF532 Internal/External Memory Map Rev. E | Page 6 of 60 | July 2007 ADSP-BF531/ADSP-BF532/ADSP-BF533 Each event type has an associated register to hold the return address and an associated return-from-event instruction. When an event is triggered, the state of the processor is saved on the supervisor stack. The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor event controller consists of two stages, the core event controller (CEC) and the system interrupt controller (SIC). The core event con troller works with the system interrupt controller to prioritize and control all system events. Conceptually, interrupts from the peripherals enter into the SIC, and are then routed directly into the general-purpose interrupts of the CEC. Table 3.

Of these general-purpose interrupts, the two lowest priority inter rupts (IVG15-14) are recommended to be reserved for software interrupt handlers, leaving seven prioritized interrupt inputs to support the peripherals of the processor. Table 2 describes the inputs to the CEC, identifies their names in the event vector table (EVT), and lists their priorities. Table 2. Core Event Controller (CEC) Priority (0 is Highest) 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Event Class Emulation/Test Control Reset Nonmaskable Interrupt Exception Reserved Hardware Error Core Timer General Interrupt 7 General Interrupt 8 General Interrupt 9 General Interrupt 10 General Interrupt 11 General Interrupt 12 General Interrupt 13 General Interrupt 14 General Interrupt 15 EVT Entry EMU RST NMI EVX IVHW IVTMR IVG7 IVG8 IVG9 IVG10 IVG11 IVG12 IVG13 IVG14 IVG15 Event Control The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor pro vides the user with a very flexible mechanism to control the processing of events. In the CEC, three registers are used to coordinate and control events. Each register is 32 bits wide: * CEC interrupt latch register (ILAT) - The ILAT register indicates when events have been latched. The appropriate bit is set when the processor has latched the event and cleared when the event has been accepted into the system. This register is updated automatically by the controller, but it may also be written to clear (cancel) latched events. This register may be read while in supervisor mode and may only be written while in supervisor mode when the corre sponding IMASK bit is cleared. * CEC interrupt mask register (IMASK) - The IMASK regis ter controls the masking and unmasking of individual events. When a bit is set in the IMASK register, that event is unmasked and will be processed by the CEC when asserted. A cleared bit in the IMASK register masks the event, preventing the processor from servicing the event even though the event may be latched in the ILAT register. This register may be read or written while in supervisor mode. System Interrupt Controller (SIC) The system interrupt controller provides the mapping and rout ing of events from the many peripheral interrupt sources to the prioritized general-purpose interrupt inputs of the CEC. Although the ADSP-BF531/ADSP-BF532/ADSP-BF533 proces sor provides a default mapping, the user can alter the mappings and priorities of interrupt events by writing the appropriate val ues into the interrupt assignment registers (SIC_IARx). Table 3 describes the inputs into the SIC and the default mappings into the CEC. Rev. E | Page 7 of 60 | July 2007 ADSP-BF531/ADSP-BF532/ADSP-BF533 Note that general-purpose interrupts can be globally enabled and disabled with the STI and CLI instructions, respectively. * CEC interrupt pending register (IPEND) - The IPEND register keeps track of all nested events. A set bit in the IPEND register indicates the event is currently active or nested at some level. This register is updated automatically by the controller but may be read while in supervisor mode. The SIC allows further control of event processing by providing three 32-bit interrupt control and status registers. Each register contains a bit corresponding to each of the peripheral interrupt events shown in Table 3. * SIC interrupt mask register (SIC_IMASK) - This register controls the masking and unmasking of each peripheral interrupt event. When a bit is set in this register, that peripheral event is unmasked and will be processed by the system when asserted. A cleared bit in this register masks the peripheral event, preventing the processor from servic ing the event. * SIC interrupt status register (SIC_ISR) - As multiple peripherals can be mapped to a single event, this register allows the software to determine which peripheral event source triggered the interrupt. A set bit indicates the peripheral is asserting the interrupt, and a cleared bit indi cates the peripheral is not asserting the event. * SIC interrupt wakeup enable register (SIC_IWR) - By enabling the corresponding bit in this register, a peripheral can be configured to wake up the processor, should the core be idled when the event is generated. See Dynamic Power Management on Page 11. Because multiple interrupt sources can map to a single generalpurpose interrupt, multiple pulse assertions can occur simulta neously, before or during interrupt processing for an interrupt event already detected on this interrupt input. The IPEND reg ister contents are monitored by the SIC as the interrupt acknowledgement. The appropriate ILAT register bit is set when an interrupt rising edge is detected (detection requires two core clock cycles). The bit is cleared when the respective IPEND register bit is set. The IPEND bit indicates that the event has entered into the proces sor pipeline. At this point the CEC will recognize and queue the next rising edge event on the corresponding event input. The minimum latency from the rising edge transition of the generalpurpose interrupt to the IPEND output asserted is three core clock cycles; however, the latency can be much higher, depend ing on the activity within and the state of the processor. and the asynchronous memory controller. DMA-capable peripherals include the SPORTs, SPI port, UART, and PPI. Each individual DMA-capable peripheral has at least one dedicated DMA channel. The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor DMA controller supports both 1-dimensional (1-D) and 2-dimen sional (2-D) DMA transfers. DMA transfer initialization can be implemented from registers or from sets of parameters called descriptor blocks. The 2-D DMA capability supports arbitrary row and column sizes up to 64K elements by 64K elements, and arbitrary row and column step sizes up to 32K elements. Furthermore, the column step size can be less than the row step size, allowing implementation of interleaved data streams. This feature is especially useful in video applications where data can be de-interleaved on the fly. Examples of DMA types supported by the ADSP-BF531/ ADSP-BF532/ADSP-BF533 processor DMA controller include: * A single, linear buffer that stops upon completion * A circular, autorefreshing buffer that interrupts on each full or fractionally full buffer * 1-D or 2-D DMA using a linked list of descriptors * 2-D DMA using an array of descriptors, specifying only the base DMA address within a common page In addition to the dedicated peripheral DMA channels, there are two pairs of memory DMA channels provided for transfers between the various memories of the ADSP-BF531/ ADSP-BF532/ADSP-BF533 processor system. This enables transfers of blocks of data between any of the memories-- including external SDRAM, ROM, SRAM, and flash memory-- with minimal processor intervention. Memory DMA transfers can be controlled by a very flexible descriptor-based methodol ogy or by a standard register-based autobuffer mechanism. REAL-TIME CLOCK The processor real-time clock (RTC) provides a robust set of digital watch features, including current time, stopwatch, and alarm. The RTC is clocked by a 32.768 kHz crystal external to the ADSP-BF531/ADSP-BF532/ADSP-BF533 processor. The RTC peripheral has dedicated power supply pins so that it can remain powered up and clocked even when the rest of the pro cessor is in a low power state. The RTC provides several programmable interrupt options, including interrupt per sec ond, minute, hour, or day clock ticks, interrupt on programmable stopwatch countdown, or interrupt at a pro grammed alarm time. The 32.768 kHz input clock frequency is divided down to a 1 Hz signal by a prescaler. The counter function of the timer consists of four counters: a 60 second counter, a 60 minute counter, a 24 hour counter, and a 32,768 day counter. When enabled, the alarm function generates an interrupt when the output of the timer matches the programmed value in the alarm control register. There are two alarms: The first alarm is for a time of day. The second alarm is for a day and time of that day. July 2007 DMA CONTROLLERS The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor has multiple, independent DMA channels that support automated data transfers with minimal overhead for the processor core. DMA transfers can occur between the processor's internal memories and any of its DMA-capable peripherals. Addition ally, DMA transfers can be accomplished between any of the DMA-capable peripherals and external devices connected to the external memory interfaces, including the SDRAM controller Rev. E | Page 8 of 60 | ADSP-BF531/ADSP-BF532/ADSP-BF533 The stopwatch function counts down from a programmed value, with one second resolution. When the stopwatch is enabled and the counter underflows, an interrupt is generated. Like other peripherals, the RTC can wake up the processor from sleep mode upon generation of any RTC wakeup event. Additionally, an RTC wakeup event can wake up the processor from deep sleep mode, and wake up the on-chip internal voltage regulator from a powered-down state. Connect RTC pins RTXI and RTXO with external components as shown in Figure 6. RTXI R1 RTXO clock the timer, or as a mechanism for measuring pulse widths and periods of external events. These timers can be synchro nized to an external clock input to the PF1 pin (TACLK), an external clock input to the PPI_CLK pin (TMRCLK), or to the internal SCLK. The timer units can be used in conjunction with the UART to measure the width of the pulses in the data stream to provide an autobaud detect function for a serial channel. The timers can generate interrupts to the processor core provid ing periodic events for synchronization, either to the system clock or to a count of external signals. In addition to the three general-purpose programmable timers, a fourth timer is also provided. This extra timer is clocked by the internal processor clock and is typically used as a system tick clock for generation of operating system periodic interrupts. X1 C1 C2 SERIAL PORTS (SPORTs) The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor incor porates two dual-channel synchronous serial ports (SPORT0 and SPORT1) for serial and multiprocessor communications. The SPORTs support the following features: * I2S capable operation. * Bidirectional operation - Each SPORT has two sets of inde pendent transmit and receive pins, enabling eight channels of I2S stereo audio. * Buffered (8-deep) transmit and receive ports - Each port has a data register for transferring data words to and from other processor components and shift registers for shifting data in and out of the data registers. * Clocking - Each transmit and receive port can either use an external serial clock or generate its own, in frequencies ranging from (fSCLK/131,070) Hz to (fSCLK/2) Hz. * Word length - Each SPORT supports serial data words from 3 bits to 32 bits in length, transferred most-signifi cant-bit first or least-significant-bit first. * Framing - Each transmit and receive port can run with or without frame sync signals for each data word. Frame sync signals can be generated internally or externally, active high or low, and with either of two pulse widths and early or late frame sync. * Companding in hardware - Each SPORT can perform A-law or -law companding according to ITU recommen dation G.711. Companding can be selected on the transmit and/or receive channel of the SPORT without additional latencies. * DMA operations with single-cycle overhead - Each SPORT can automatically receive and transmit multiple buffers of memory data. The processor can link or chain sequences of DMA transfers between a SPORT and memory.

External Components for RTC WATCHDOG TIMER The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor includes a 32-bit timer that can be used to implement a software watchdog function. A software watchdog can improve system availability by forcing the processor to a known state through generation of a hardware reset, nonmaskable interrupt (NMI), or general-purpose interrupt, if the timer expires before being reset by software. The programmer initializes the count value of the timer, enables the appropriate interrupt, then enables the timer. Thereafter, the software must reload the counter before it counts to zero from the programmed value. This protects the system from remaining in an unknown state where software, which would normally reset the timer, has stopped running due to an external noise condition or software error. If configured to generate a hardware reset, the watchdog timer resets both the core and the processor peripherals. After a reset, software can determine if the watchdog was the source of the hardware reset by interrogating a status bit in the watchdog timer control register. The timer is clocked by the system clock (SCLK), at a maximum frequency of fSCLK. TIMERS There are four general-purpose programmable timer units in the ADSP-BF531/ADSP-BF532/ADSP-BF533 processor. Three timers have an external pin that can be configured either as a pulse-width modulator (PWM) or timer output, as an input to Rev. E | Page 9 of 60 | July 2007 ADSP-BF531/ADSP-BF532/ADSP-BF533 * Interrupts - Each transmit and receive port generates an interrupt upon completing the transfer of a data-word or after transferring an entire data buffer or buffers through DMA. * Multichannel capability - Each SPORT supports 128 chan nels out of a 1,024-channel window and is compatible with the H.100, H.110, MVIP-90, and HMVIP standards. An additional 250 mV of SPORT input hysteresis can be enabled by setting Bit 15 of the PLL_CTL register. When this bit is set, all SPORT input pins have the increased hysteresis. data to and from memory. The UART has two dedicated DMA channels, one for transmit and one for receive. These DMA channels have lower default priority than most DMA channels because of their relatively low service rates. The baud rate, serial data format, error code generation and sta tus, and interrupts for the UART port are programmable. The UART programmable features include: * Supporting bit rates ranging from (fSCLK/1,048,576) bits per second to (fSCLK/16) bits per second. * Supporting data formats from seven bits to 12 bits per frame. * Both transmit and receive operations can be configured to generate maskable interrupts to the processor. The UART port's clock rate is calculated as: f SCLK UART Clock Rate = ---------------------------------------------16 x UART_Divisor Where the 16-bit UART_Divisor comes from the UART_DLH register (most significant 8 bits) and UART_DLL register (least significant 8 bits). In conjunction with the general-purpose timer functions, autobaud detection is supported. The capabilities of the UART are further extended with support for the Infrared Data Association (IrDA) serial infrared physical layer link specification (SIR) protocol. SERIAL PERIPHERAL INTERFACE (SPI) PORT The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor has an SPI-compatible port that enables the processor to communicate with multiple SPI-compatible devices. The SPI interface uses three pins for transferring data: two data pins (master output-slave input, MOSI, and master input-slave output, MISO) and a clock pin (serial clock, SCK). An SPI chip select input pin (SPISS) lets other SPI devices select the proces sor, and seven SPI chip select output pins (SPISEL7-1) let the processor select other SPI devices. The SPI select pins are reconfigured general-purpose I/O pins. Using these pins, the SPI port provides a full-duplex, synchronous serial interface which sup ports both master/slave modes and multimaster environments. The baud rate and clock phase/polarities for the SPI port are programmable, and it has an integrated DMA controller, con figurable to support transmit or receive data streams. The SPI DMA controller can only service unidirectional accesses at any given time. The SPI port clock rate is calculated as: f SCLK SPI Clock Rate = ----------------------------------2 x SPI_BAUD Where the 16-bit SPI_BAUD register contains a value of 2 to 65,535. During transfers, the SPI port simultaneously transmits and receives by serially shifting data in and out on its two serial data lines. The serial clock line synchronizes the shifting and sam pling of data on the two serial data lines. GENERAL-PURPOSE I/O PORT F The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor has 16 bidirectional, general-purpose I/O pins on Port F (PF15-0). Each general-purpose I/O pin can be individually controlled by manipulation of the GPIO control, status and interrupt registers: * GPIO direction control register - Specifies the direction of each individual PFx pin as input or output. * GPIO control and status registers - The ADSP-BF531/ ADSP-BF532/ADSP-BF533 processor employs a "write one to modify" mechanism that allows any combination of individual GPIO pins to be modified in a single instruction, without affecting the level of any other GPIO pins. Four control registers are provided. One register is written in order to set GPIO pin values, one register is written in order to clear GPIO pin values, one register is written in order to toggle GPIO pin values, and one register is written in order to specify GPIO pin values. Reading the GPIO sta tus register allows software to interrogate the sense of the GPIO pin. * GPIO interrupt mask registers - The two GPIO interrupt mask registers allow each individual PFx pin to function as an interrupt to the processor. Similar to the two GPIO con trol registers that are used to set and clear individual GPIO pin values, one GPIO interrupt mask register sets bits to enable interrupt function, and the other GPIO interrupt mask register clears bits to disable interrupt function. PFx UART PORT The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor pro vides a full-duplex universal asynchronous receiver/transmitter (UART) port, which is fully compatible with PC-standard UARTs. The UART port provides a simplified UART interface to other peripherals or hosts, supporting full-duplex, DMA-sup ported, asynchronous transfers of serial data. The UART port includes support for 5 data bits to 8 data bits, 1 stop bit or 2 stop bits, and none, even, or odd parity. The UART port supports two modes of operation: * PIO (programmed I/O) - The processor sends or receives data by writing or reading I/O-mapped UART registers. The data is double-buffered on both transmit and receive. * DMA (direct memory access) - The DMA controller trans fers both transmit and receive data. This reduces the number and frequency of interrupts required to transfer Rev. E | Page 10 of 60 | July 2007 ADSP-BF531/ADSP-BF532/ADSP-BF533 pins defined as inputs can be configured to generate hard ware interrupts, while output PFx pins can be triggered by software interrupts. * GPIO interrupt sensitivity registers - The two GPIO inter rupt sensitivity registers specify whether individual PFx pins are level- or edge-sensitive and specify--if edge-sensi tive--whether just the rising edge or both the rising and falling edges of the signal are significant. One register selects the type of sensitivity, and one register selects which edges are significant for edge-sensitivity. Frame Capture Mode Frame capture mode allows the video source(s) to act as a slave (e.g., for frame capture). The ADSP-BF531/ADSP-BF532/ ADSP-BF533 processors control when to read from the video source(s). PPI_FS1 is an HSYNC output and PPI_FS2 is a VSYNC output. Output Mode Output mode is used for transmitting video or other data with up to three output frame syncs. Typically, a single frame sync is appropriate for data converter applications, whereas two or three frame syncs could be used for sending video with hard ware signaling. PARALLEL PERIPHERAL INTERFACE The processor provides a parallel peripheral interface (PPI) that can connect directly to parallel A/D and D/A converters, video encoders and decoders, and other general-purpose peripherals. The PPI consists of a dedicated input clock pin, up to three frame synchronization pins, and up to 16 data pins. The input clock supports parallel data rates up to half the system clock rate and the synchronization signals can be configured as either inputs or outputs. The PPI supports a variety of general-purpose and ITU-R 656 modes of operation. In general-purpose mode, the PPI provides half-duplex, bi-directional data transfer with up to 16 bits of data. Up to three frame synchronization signals are also pro vided. In ITU-R 656 mode, the PPI provides half-duplex bi directional transfer of 8- or 10-bit video data. Additionally, onchip decode of embedded start-of-line (SOL) and start-of-field (SOF) preamble packets is supported. ITU-R 656 Mode Descriptions The ITU-R 656 modes of the PPI are intended to suit a wide variety of video capture, processing, and transmission applica tions. Three distinct submodes are supported: * Active video only mode * Vertical blanking only mode * Entire field mode Active Video Only Mode Active video only mode is used when only the active video por tion of a field is of interest and not any of the blanking intervals. The PPI does not read in any data between the end of active video (EAV) and start of active video (SAV) preamble symbols, or any data present during the vertical blanking intervals. In this mode, the control byte sequences are not stored to memory; they are filtered by the PPI. After synchronizing to the start of Field 1, the PPI ignores incoming samples until it sees an SAV code. The user specifies the number of active video lines per frame (in PPI_COUNT register). General-Purpose Mode Descriptions The general-purpose modes of the PPI are intended to suit a wide variety of data capture and transmission applications. Three distinct submodes are supported: * Input mode - Frame syncs and data are inputs into the PPI. * Frame capture mode - Frame syncs are outputs from the PPI, but data are inputs. * Output mode - Frame syncs and data are outputs from the PPI. Vertical Blanking Interval Mode In this mode, the PPI only transfers vertical blanking interval (VBI) data. Entire Field Mode In this mode, the entire incoming bit stream is read in through the PPI. This includes active video, control preamble sequences, and ancillary data that may be embedded in horizontal and ver tical blanking intervals. Data transfer starts immediately after synchronization to Field 1. Data is transferred to or from the synchronous channels through eight DMA engines that work autonomously from the processor core. Input Mode Input mode is intended for ADC applications, as well as video communication with hardware signaling. In its simplest form, PPI_FS1 is an external frame sync input that controls when to read data. The PPI_DELAY MMR allows for a delay (in PPI_CLK cycles) between reception of this frame sync and the initiation of data reads. The number of input data samples is user programmable and defined by the contents of the PPI_COUNT register. The PPI supports 8-bit and 10-bit through 16-bit data, programmable in the PPI_CONTROL register. DYNAMIC POWER MANAGEMENT The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor pro vides four operating modes, each with a different performance/ power profile. In addition, dynamic power management pro vides the control functions to dynamically alter the processor core supply voltage, further reducing power dissipation. Control of clocking to each of the processor peripherals also reduces power consumption. See Table 4 for a summary of the power settings for each mode. Rev. E | Page 11 of 60 | July 2007 ADSP-BF531/ADSP-BF532/ADSP-BF533 Full-On Operating Mode--Maximum Performance In the full-on mode, the PLL is enabled and is not bypassed, providing capability for maximum operational frequency. This is the power-up default execution state in which maximum per formance can be achieved. The processor core and all enabled peripherals run at full speed. interrupt causes the processor to transition to the active mode. Assertion of RESET while in deep sleep mode causes the proces sor to transition to the full-on mode. Hibernate State--Maximum Static Power Savings The hibernate state maximizes static power savings by disabling the voltage and clocks to the processor core (CCLK) and to all the synchronous peripherals (SCLK). The internal voltage regu lator for the processor can be shut off by writing b#00 to the FREQ bits of the VR_CTL register. In addition to disabling the clocks, this sets the internal power supply voltage (VDDINT) to 0 V to provide the lowest static power dissipation. Any critical information stored internally (memory contents, register con tents, etc.) must be written to a nonvolatile storage device prior to removing power if the processor state is to be preserved. Since VDDEXT is still supplied in this mode, all of the external pins three-state, unless otherwise specified. This allows other devices that may be connected to the processor to still have power applied without drawing unwanted current. The internal supply regulator can be woken up either by a real-time clock wakeup or by asserting the RESET pin. Active Operating Mode--Moderate Power Savings In the active mode, the PLL is enabled but bypassed. Because the PLL is bypassed, the processor's core clock (CCLK) and system clock (SCLK) run at the input clock (CLKIN) frequency. In this mode, the CLKIN to CCLK multiplier ratio can be changed, although the changes are not realized until the full-on mode is entered. DMA access is available to appropriately configured L1 memories. In the active mode, it is possible to disable the PLL through the PLL control register (PLL_CTL). If disabled, the PLL must be re-enabled before transitioning to the full-on or sleep modes. Table 4. Power Settings PLL Mode PLL Bypassed Full-On Enabled No Active Enabled/ Yes Disabled Sleep Enabled Deep Sleep Disabled Hibernate Disabled Core Clock (CCLK) Enabled Enabled System Clock Core (SCLK) Power Enabled On Enabled On Power Savings As shown in Table 5, the ADSP-BF531/ADSP-BF532/ ADSP-BF533 processor supports three different power domains. The use of multiple power domains maximizes flexi bility, while maintaining compliance with industry standards and conventions. By isolating the internal logic of the processor into its own power domain, separate from the RTC and other I/O, the processor can take advantage of dynamic power man agement without affecting the RTC or other I/O devices. There are no sequencing requirements for the various power domains. Table 5. Power Domains Power Domain All internal logic, except RTC RTC internal logic and crystal I/O All other I/O VDD Range VDDINT VDDRTC VDDEXT Disabled Enabled On Disabled Disabled On Disabled Disabled Off Sleep Operating Mode--High Dynamic Power Savings The sleep mode reduces dynamic power dissipation by disabling the clock to the processor core (CCLK). The PLL and system clock (SCLK), however, continue to operate in this mode. Typi cally an external event or RTC activity will wake up the processor. When in the sleep mode, assertion of wakeup will cause the processor to sense the value of the BYPASS bit in the PLL control register (PLL_CTL). If BYPASS is disabled, the pro cessor will transition to the full-on mode. If BYPASS is enabled, the processor will transition to the active mode. When in the sleep mode, system DMA access to L1 memory is not supported. Deep Sleep Operating Mode--Maximum Dynamic Power Savings The deep sleep mode maximizes dynamic power savings by dis abling the clocks to the processor core (CCLK) and to all synchronous peripherals (SCLK). Asynchronous peripherals, such as the RTC, may still be running but will not be able to access internal resources or external memory. This powereddown mode can only be exited by assertion of the reset interrupt (RESET) or by an asynchronous interrupt generated by the RTC. When in deep sleep mode, an RTC asynchronous The power dissipated by a processor is largely a function of the clock frequency of the processor and the square of the operating voltage. For example, reducing the clock frequency by 25% results in a 25% reduction in dynamic power dissipation, while reducing the voltage by 25% reduces dynamic power dissipation by more than 40%. Further, these power savings are additive, in that if the clock frequency and supply voltage are both reduced, the power savings can be dramatic. The dynamic power management feature of the ADSP-BF531/ ADSP-BF532/ADSP-BF533 processor allows both the proces sor's input voltage (VDDINT) and clock frequency (fCCLK) to be dynamically controlled. The savings in power dissipation can be modeled using the power savings factor and % power savings calculations. Rev. E | Page 12 of 60 | July 2007 ADSP-BF531/ADSP-BF532/ADSP-BF533 The power savings factor is calculated as: power savings factor f CCLKRED V DDINTRED 2 t RED = -------------------- x ------------------------- x ---------- f CCLKNOM V DDINTNOM t NOM where the variables in the equation are: fCCLKNOM is the nominal core clock frequency fCCLKRED is the reduced core clock frequency VDDINTNOM is the nominal internal supply voltage VDDINTRED is the reduced internal supply voltage tNOM is the duration running at fCCLKNOM tRED is the duration running at fCCLKRED The percent power savings is calculated as: % power savings = (1 - power savings factor) x 100% Voltage Regulator Layout Guidelines Regulator external component placement, board routing, and bypass capacitors all have a significant effect on noise injected into the other analog circuits on-chip. The VROUT1-0 traces and voltage regulator external components should be consid ered as noise sources when doing board layout and should not be routed or placed near sensitive circuits or components on the board. All internal and I/O power supplies should be well bypassed with bypass capacitors placed as close to the ADSP-BF531/ADSP-BF532/ADSP-BF533 processors as possible. For further details on the on-chip voltage regulator and related board design guidelines, see the Switching Regulator Design Considerations for ADSP-BF533 Blackfin Processors (EE-228) applications note on the Analog Devices web site (www.ana log.com)--use site search on "EE-228". VOLTAGE REGULATION The Blackfin processor provides an on-chip voltage regulator that can generate appropriate VDDINT voltage levels from the VDDEXT supply. See Operating Conditions on Page 21 for regula tor tolerances and acceptable VDDEXT ranges for specific models. Figure 7 shows the typical external components required to complete the power management system. The regulator con trols the internal logic voltage levels and is programmable with the voltage regulator control register (VR_CTL) in increments of 50 mV. To reduce standby power consumption, the internal voltage regulator can be programmed to remove power to the processor core while keeping I/O power (VDDEXT) supplied. While in the hibernate state, I/O power is still being applied, eliminat ing the need for external buffers. The voltage regulator can be activated from this power-down state either through an RTC wakeup or by asserting RESET, both of which will then initiate a boot sequence. The regulator can also be disabled and bypassed at the user's discretion. CLOCK SIGNALS The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor can be clocked by an external crystal, a sine wave input, or a buffered, shaped clock derived from an external clock oscillator. If an external clock is used, it should be a TTL compatible signal and must not be halted, changed, or operated below the speci fied frequency during normal operation. This signal is connected to the processor's CLKIN pin. When an external clock is used, the XTAL pin must be left unconnected. Alternatively, because the ADSP-BF531/ADSP-BF532/ ADSP-BF533 processor includes an on-chip oscillator circuit, an external crystal may be used. For fundamental frequency operation, use the circuit shown in Figure 8.

Voltage Regulator Circuit A parallel-resonant, fundamental frequency, microprocessorgrade crystal is connected across the CLKIN and XTAL pins. The on-chip resistance between CLKIN and the XTAL pin is in the 500 k range. Further parallel resistors are typically not rec ommended. The two capacitors and the series resistor shown in Figure 8 fine tune the phase and amplitude of the sine Rev. E | Page 13 of 60 | July 2007 ADSP-BF531/ADSP-BF532/ADSP-BF533 frequency. The capacitor and resistor values shown in Figure 8 are typical values only. The capacitor values are dependent upon the crystal manufacturer's load capacitance recommendations and the physical PCB layout. The resistor value depends on the drive level specified by the crystal manufacturer. System designs should verify the customized values based on careful investiga tion on multiple devices over the allowed temperature range. A third-overtone crystal can be used at frequencies above 25 MHz. The circuit is then modified to ensure crystal operation only at the third overtone, by adding a tuned inductor circuit as shown in Figure 8. As shown in Figure 9, the core clock (CCLK) and system peripheral clock (SCLK) are derived from the input clock (CLKIN) signal. An on-chip PLL is capable of multiplying the CLKIN signal by a user programmable 0.5x to 64x multiplica tion factor (bounded by specified minimum and maximum VCO frequencies). The default multiplier is 10x, but it can be modified by a software instruction sequence. On-the-fly frequency changes can be effected by simply writing to the PLL_DIV register. "FI NE" ADJUSTMENT REQUI RES PLL SEQ UENCING "CO ARSE" ADJUSTMENT ON-THE-FLY to the PLL divisor register (PLL_DIV). When the SSEL value is changed, it will affect all the peripherals that derive their clock signals from the SCLK signal. The core clock (CCLK) frequency can also be dynamically changed by means of the CSEL1-0 bits of the PLL_DIV register. Supported CCLK divider ratios are 1, 2, 4, and 8, as shown in Table 7. This programmable core clock capability is useful for fast core frequency modifications. Table 7.

A third mode is provided to execute from external memory, bypassing the boot sequence. Table 8.

Frequency Modification Methods All on-chip peripherals are clocked by the system clock (SCLK). The system clock frequency is programmable by means of the SSEL3-0 bits of the PLL_DIV register. The values programmed into the SSEL fields define a divide ratio between the PLL output (VCO) and the system clock. SCLK divider values are 1 through 15. Table 6 illustrates typical system clock ratios. Table 6.

The boot ROM is bypassed in this mode. All configuration settings are set for the slowest device possible (3-cycle hold time; 15-cycle R/W access times; 4-cycle setup). * Boot from 8-bit or 16-bit external flash memory - The flash boot routine located in boot ROM memory space is set up using asynchronous Memory Bank 0. All configuration set tings are set for the slowest device possible (3-cycle hold time; 15-cycle R/W access times; 4-cycle setup). * Boot from SPI serial EEPROM/flash (8-, 16-, or 24-bit addressable, or Atmel AT45DB041, AT45DB081, or AT45DB161) - The SPI uses the PF2 output pin to select a single SPI EEPROM/flash device, submits a read command and successive address bytes (0x00) until a valid 8-, 16-, or Signal Name SSEL3-0 0001 0011 1010 The maximum frequency of the system clock is fSCLK.

To hold off the host device from transmitting while the boot ROM is busy, the Blackfin processor asserts a GPIO pin, called host wait (HWAIT), to signal the host device not to send any more bytes until the flag is deasserted. The GPIO pin is chosen by the user and this information is transferred to the Blackfin processor via bits[10:5] of the FLAG header in the LDR image. For each of the boot modes, a 10-byte header is first read from an external memory device. The header specifies the number of bytes to be transferred and the memory destination address. Multiple memory blocks may be loaded by any boot sequence. Once all blocks are loaded, program execution commences from the start of L1 instruction SRAM. In addition, Bit 4 of the reset configuration register can be set by application code to bypass the normal boot sequence during a software reset. For this case, the processor jumps directly to the beginning of L1 instruction memory. * Microcontroller features, such as arbitrary bit and bit-field manipulation, insertion, and extraction; integer operations on 8-, 16-, and 32-bit data types; and separate user and supervisor stack pointers. * Code density enhancements, which include intermixing of 16-bit and 32-bit instructions (no mode switching, no code segregation). Frequently used instructions are encoded in 16 bits. DEVELOPMENT TOOLS The ADSP-BF531/ADSP-BF532/ADSP-BF533 processor is sup ported by a complete set of CROSSCORE(R) software and hardware development tools, including Analog Devices emula tors and VisualDSP++(R) development environment. The same emulator hardware that supports other Blackfin processors also fully emulates the ADSP-BF531/ADSP-BF532/ADSP-BF533 processor. The VisualDSP++ project management environment lets pro grammers develop and debug an application. This environment includes an easy to use assembler (which is based on an alge braic syntax), an archiver (librarian/library builder), a linker, a loader, a cycle-accurate instruction level simulator, a C/C++ compiler, and a C/C++ runtime library that includes DSP and mathematical functions. A key point for these tools is C/C++ code efficiency. The compiler has been developed for efficient translation of C/C++ code to processor assembly. The processor has architectural features that improve the efficiency of com piled C/C++ code. The VisualDSP++ debugger has a number of important fea tures. Data visualization is enhanced by a plotting package that offers a significant level of flexibility. This graphical representa tion of user data enables the programmer to quickly determine the performance of an algorithm. As algorithms grow in com plexity, this capability can have increasing significance on the designer's development schedule, increasing productivity. Statistical profiling enables the programmer to nonintrusively poll the processor as it is running the program. This feature, unique to VisualDSP++, enables the software developer to pas sively gather important code execution metrics without interrupting the real-time characteristics of the program. Essen tially, the developer can identify bottlenecks in software quickly and efficiently. By using the profiler, the programmer can focus on those areas in the program that impact performance and take corrective action. Debugging both C/C++ and assembly programs with the VisualDSP++ debugger, programmers can: * View mixed C/C++ and assembly code (interleaved source and object information). * Insert breakpoints. * Set conditional breakpoints on registers, memory, and stacks. INSTRUCTION SET DESCRIPTION The Blackfin processor family assembly language instruction set employs an algebraic syntax designed for ease of coding and readability. The instructions have been specifically tuned to pro vide a flexible, densely encoded instruction set that compiles to a very small final memory size. The instruction set also provides fully featured multifunction instructions that allow the pro grammer to use many of the processor core resources in a single instruction. Coupled with many features more often seen on microcontrollers, this instruction set is very efficient when com piling C and C++ source code. In addition, the architecture supports both user (algorithm/application code) and supervisor (O/S kernel, device drivers, debuggers, ISRs) modes of opera tion, allowing multiple levels of access to core processor resources. The assembly language, which takes advantage of the proces sor's unique architecture, offers the following advantages: * Seamlessly integrated DSP/CPU features are optimized for both 8-bit and 16-bit operations. * A multi-issue load/store modified Harvard architecture, which supports two 16-bit MAC or four 8-bit ALU + two load/store + two pointer updates per cycle. * All registers, I/O, and memory are mapped into a unified 4G byte memory space, providing a simplified program ming model.

E | Page 15 of 60 | July 2007 ADSP-BF531/ADSP-BF532/ADSP-BF533 * Trace instruction execution. * Perform linear or statistical profiling of program execution. * Fill, dump, and graphically plot the contents of memory. * Perform source level debugging. * Create custom debugger windows. The VisualDSP++ IDDE lets programmers define and manage software development. Its dialog boxes and property pages let programmers configure and manage all of the Blackfin develop ment tools, including the color syntax highlighting in the VisualDSP++ editor. This capability permits programmers to: * Control how the development tools process inputs and generate outputs * Maintain a one-to-one correspondence with the tool's command line switches The VisualDSP++ Kernel (VDK) incorporates scheduling and resource management tailored specifically to address the mem ory and timing constraints of DSP programming. These capabilities enable engineers to develop code more effectively, eliminating the need to start from the very beginning, when developing new application code. The VDK features include threads, critical and unscheduled regions, semaphores, events, and device flags. The VDK also supports priority-based, pre emptive, cooperative, and time-sliced scheduling approaches. In addition, the VDK was designed to be scalable. If the application does not use a specific feature, the support code for that feature is excluded from the target system. Because the VDK is a library, a developer can decide whether to use it or not. The VDK is integrated into the VisualDSP++ development environment, but can also be used via standard command line tools. When the VDK is used, the development environment assists the developer with many error prone tasks and assists in managing system resources, automating the gen eration of various VDK-based objects, and visualizing the system state, when debugging an application that uses the VDK. Use the expert linker to visually manipulate the placement of code and data on the embedded system. View memory utiliza tion in a color coded graphical form, easily move code and data to different areas of the processor or external memory with the drag of the mouse, and examine runtime stack and heap usage. The expert linker is fully compatible with existing linker defini tion file (LDF), allowing the developer to move between the graphical and textual environments. Analog Devices emulators use the IEEE 1149.1 JTAG test access port of the ADSP-BF531/ADSP-BF532/ADSP-BF533 processor to monitor and control the target board processor during emu lation. The emulator provides full speed emulation, allowing inspection and modification of memory, registers, and proces sor stacks. Nonintrusive in-circuit emulation is assured by the use of the processor's JTAG interface--the emulator does not affect target system loading or timing. In addition to the software and hardware development tools available from Analog Devices, third parties provide a wide range of tools supporting the Blackfin processor family. Hardware tools include Blackfin processor PC plug-in cards. Third party software tools include DSP libraries, real-time oper ating systems, and block diagram design tools. EZ-KIT Lite Evaluation Board Analog Devices offers a range of EZ-KIT Lite(R) evaluation plat forms to use as a cost effective method to learn more about developing or prototyping applications with Analog Devices processors, platforms, and software tools. Each EZ-KIT Lite includes an evaluation board along with an evaluation suite of the VisualDSP++ development and debugging environment with the C/C++ compiler, assembler, and linker. Also included are sample application programs, power supply, and a USB cable. All evaluation versions of the software tools are limited for use only with the EZ-KIT Lite product. The USB controller on the EZ-KIT Lite board connects the board to the USB port of the user's PC, enabling the Visu alDSP++ evaluation suite to emulate the on-board processor incircuit. This permits the customer to download, execute, and debug programs for the EZ-KIT Lite system. It also allows incircuit programming of the on-board flash device to store userspecific boot code, enabling the board to run as a standalone unit without being connected to the PC. With a full version of VisualDSP++ installed (sold separately), engineers can develop software for the EZ-KIT Lite or any cus tom defined system. Connecting one of Analog Devices JTAG emulators to the EZ-KIT Lite board enables high speed, nonintrusive emulation. For evaluation of ADSP-BF531/ADSP-BF532/ADSP-BF533 processors, use the EZ-KIT Lite board available from Analog Devices. Order part number ADDS-BF533-EZLITE. The board comes with on-chip emulation capabilities and is equipped to enable software development. Multiple daughter cards are available. DESIGNING AN EMULATOR-COMPATIBLE PROCESSOR BOARD The Analog Devices family of emulators are tools that every sys tem developer needs to test and debug hardware and software systems. Analog Devices has supplied an IEEE 1149.1 JTAG test access port (TAP) on each JTAG processor. The emulator uses the TAP to access the internal features of the processor, allow ing the developer to load code, set breakpoints, observe variables, observe memory, and examine registers. The proces sor must be halted to send data and commands, but once an operation has been completed by the emulator, the processor system is set running at full speed with no impact on system timing. To use these emulators, the target board must include a header that connects the processor's JTAG port to the emulator. Rev.

All pins are three-stated during and immediately after reset, except the memory interface, asynchronous memory control, and synchronous memory control pins, which are driven high. If BR is active, then the memory pins are also three-stated. All unused I/O pins have their input buffers disabled with the exception of the pins that need pull-ups or pull-downs as noted in the table footnotes. In order to maintain maximum functionality and reduce pack age size and pin count, some pins have dual, multiplexed functionality. In cases where pin functionality is reconfigurable, the default state is shown in plain text, while alternate function ality is shown in italics. Table 9.

Time tTRIP is the interval from when the output starts driving to when the output reaches the VTRIP (high) or VTRIP (low) trip voltage. Time tENA is calculated as shown in the equation: t ENA = t ENA_MEASURED - t TRIP If multiple pins (such as the data bus) are enabled, the measure ment value is that of the first pin to start driving. 50 0 VOH -50 VOL -100 Output Disable Time Measurement Output pins are considered to be disabled when they stop driv ing, go into a high impedance state, and start to decay from their output high or low voltage. The output disable time tDIS is the difference between tDIS_MEASURED and tDECAY as shown on the left side of Figure 42. t DIS = t DIS_MEASURED - t DECAY The time for the voltage on the bus to decay by V is dependent on the capacitive load CL and the load current II. This decay time can be approximated by the equation: t DECAY = (C L V) I L The time tDECAY is calculated with test loads CL and IL, and with V equal to 0.1 V for VDDEXT (nominal) = 1.8 V or 0.5 V for VDDEXT (nominal) = 2.5 V/3.3 V. The time tDIS_MEASURED is the interval from when the reference signal switches, to when the output voltage decays V from the measured output high or output low voltage. -150 0 0.5 1.0 1.5 2.0 SOURCE VOLTAGE (V) 2.5 3.0 3.5 Figure 41. Drive Current D (VDDEXT = 3.3 V) POWER DISSIPATION Many operating conditions can affect power dissipation. System designers should refer to Estimating Power for ADSP-BF531/ BF532/BF533 Blackfin Processors (EE-229) on the Analog Devices website (www.analog.com)--use site search on "EE-229." This document provides detailed information for optimizing your design for lowest power. See the ADSP-BF533 Blackfin Processor Hardware Reference Manual for definitions of the various operating modes and for instructions on how to minimize system power.

Voltage Reference Levels for AC Measurements (Except Output Enable/Disable) OUTPUT STOPS DRIVING OUTPUT STARTS DRIVING HIGH IMPEDANCE STATE Output Enable Time Measurement Output pins are considered to be enabled when they have made a transition from a high impedance state to the point when they start driving. The output enable time tENA is the interval from the point when a reference signal reaches a high or low voltage level to the point when the output starts driving as shown on the right side of Figure 43. The time tENA_MEASURED is the interval, from when the reference signal switches, to when the output voltage reaches VTRIP(high) or VTRIP (low). For VDDEXT (nominal) = 1.8 V--VTRIP (high) is 1.3 V and VTRIP (low) is 0.7 V. For VDDEXT (nominal) = 2.5 V/3.3 V-- Rev. E | Figure 43. Output Enable/Disable Example System Hold Time Calculation To determine the data output hold time in a particular system, first calculate tDECAY using the equation given above. Choose V to be the difference between the ADSP-BF531/ADSP-BF532/ ADSP-BF533 processor's output voltage and the input threshold for the device requiring the hold time. CLis the total bus capacitance (per data line), and IL is the total leakage or three-state current (per data line).
