Blackfin processors combine a dual-MAC, state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC-like microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture. The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors are completely code and pin compatible. They differ only with respect to their performance, on-chip memory, and presence of the Ethernet MAC module. Specific performance, memory, and feature configurations are shown in Table 1. Table 1. Processor Comparison ADSP-BF534 ADSP-BF536 ADSP-BF537 AUTOMOTIVE PRODUCTS Some ADSP-BF534 models are available for automotive applications with controlled manufacturing. Note that these special models may have specifications which differ from the general release models. For information on which models are available as automotive, see the Ordering Guide on Page 67. PORTABLE LOW POWER ARCHITECTURE Blackfin processors provide world-class power management and performance. They are produced with a low power and low voltage design methodology and feature on-chip dynamic power management, which is the ability to vary both the voltage and frequency of operation to significantly lower overall power consumption. This capability can result in a substantial reduction in power consumption, compared with just varying the frequency of operation. This allows longer battery life for portable appliances. SYSTEM INTEGRATION The Blackfin processor is a highly integrated system-on-a-chip solution for the next generation of embedded network-connected applications. By combining industry-standard interfaces with a high performance signal processing core, cost-effective applications can be developed quickly, without the need for costly external components. The system peripherals include an IEEE-compliant 802.3 10/100 Ethernet MAC (ADSP-BF536 and ADSP-BF537 only), a CAN 2.0B controller, a TWI controller, two UART ports, an SPI port, two serial ports (SPORTs), nine general-purpose 32-bit timers (eight with PWM capability), a real-time clock, a watchdog timer, and a parallel peripheral interface (PPI).

The processors contain dedicated network communication modules and high speed serial and parallel ports, an interrupt controller for flexible management 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 system to many application scenarios. All of the peripherals, except for the general-purpose I/O, CAN, TWI, real-time clock, and timers, are supported by a flexible DMA structure. There are also separate memory DMA channels dedicated to data transfers between the processor’s various memory spaces, including external SDRAM and asynchronous memory. Multiple on-chip buses running at up to 133 MHz provide enough bandwidth to keep the processor core running along with activity on all of the on-chip and external peripherals. 48K bytes 48K bytes 32K bytes 32K bytes — 4K bytes 2K bytes 400 MHz 208-Ball 182-Ball 32K bytes 4K bytes 2K bytes 600 MHz 208-Ball 182-Ball By integrating a rich set of industry-leading system peripherals and memory, the Blackfin processors are the platform of choice for next-generation applications that require RISC-like programmability, multimedia support, and leading-edge signal processing in one integrated package. Rev. E | Page 3 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 The Blackfin processors include an on-chip voltage regulator in support of the processors’ dynamic power management capability. The voltage regulator provides a range of core voltage levels when supplied from a single 2.25 V to 3.6 V input. The voltage regulator can be bypassed at the user’s discretion. tasks. These include bit operations such as field extract and population count, modulo 232 multiply, divide primitives, saturation and rounding, and sign/exponent detection. The set of video instructions include byte alignment and packing operations, 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 performed simultaneously on register pairs (a 16-bit high half and 16-bit low half of a compute register). If the second ALU is used, quad 16-bit operations are possible. 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 execution, 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-overhead looping. The architecture is fully interlocked, meaning that the programmer need not manage the pipeline when executing instructions with data dependencies. BLACKFIN PROCESSOR CORE As shown in Figure 2, 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 computation units process 8-, 16-, 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 ADDRESS ARITHMETIC UNIT I3 I2 I1 I0 DA1 32 DA0 32 TO MEMORY L3 L2 L1 L0 B3 B2 B1 B0 M3 M2 M1 M0 DAG1 DAG0 SP FP P5 P4 P3 P2 P1 P0 32 RAB 32 PREG SD 32 LD1 32 LD0 32 R7.H R6.H R5.H R4.H R3.H R2.H R1.H R0.H 32 32 R7.L R6.L R5.L R4.L R3.L R2.L R1.L R0.L BARREL SHIFTER 40 A0 32 40 40 40 A1 8 16 8 8 16 ASTAT SEQUENCER ALIGN 8 DECODE LOOP BUFFER CONTROL UNIT 32 DATA ARITHMETIC UNIT Figure 2. Blackfin Processor Core Rev. E | Page 4 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 The address arithmetic unit provides two addresses for simultaneous 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 management 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 instructions, 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 instruction 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 syntax 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. 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-BF534/ADSP-BF536/ADSP-BF537 processors have three blocks of on-chip memory providing high-bandwidth access to the core. The first block is the L1 instruction memory, consisting of 64K bytes SRAM, of which 16K bytes can be configured as a four-way set-associative cache. This memory is accessed at full processor speed. The second on-chip memory block is the L1 data memory, consisting of up to two banks of up to 32K bytes each. Each memory bank is configurable, offering both cache and SRAM functionality. 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. External (Off-Chip) Memory External memory is accessed via the 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 512M bytes of SDRAM. A separate row can be open for each SDRAM internal bank, and the SDRAM controller supports up to 4 internal SDRAM banks, improving overall 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 1M byte segment regardless of the size of the devices used, so that these banks are only contiguous if each is fully populated with 1M byte of memory. MEMORY ARCHITECTURE The ADSP-BF534/ADSP-BF536/ADSP-BF537 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 3). The on-chip L1 memory system is the highest performance memory available to the Blackfin processor. The off-chip memory system, accessed through the external bus interface unit (EBIU), provides expansion with SDRAM, flash memory, and SRAM, optionally accessing up to 516M bytes of physical memory. I/O Memory Space The ADSP-BF534/ADSP-BF536/ADSP-BF537 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 which contains the control MMRs for all core functions, and the other which contains the registers needed for setup and control of the onchip peripherals outside of the core. The MMRs are accessible only in supervisor mode and appear as reserved space to onchip peripherals. Rev.

ADSP-BF534/ADSP-BF536/ADSP-BF537 Memory Maps Booting The Blackfin processor contains a small on-chip boot kernel, which configures the appropriate peripheral for booting. If the Blackfin 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 16. • 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 shutdown of the system. • Exceptions – Events that occur synchronously to program flow (in other words, the exception is 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. 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 Blackfin processor event controller consists of two stages: the core event controller (CEC) and the system interrupt controller (SIC). The core event controller works with the system interrupt controller to prioritize and control all system events. Event Handling The event controller on the Blackfin processor handles all asynchronous and synchronous events to the processor. The Blackfin 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 precedence 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. Rev. E | Page 6 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 Conceptually, interrupts from the peripherals enter into the SIC, and are then routed directly into the general-purpose interrupts of the CEC.

Of these general-purpose interrupts, the two lowest priority interrupts (IVG15–14) are recommended to be reserved for software interrupt handlers, leaving seven prioritized interrupt inputs to support the peripherals of the Blackfin processor. Table 2 describes the inputs to the CEC, identifies their names in the event vector table (EVT), and lists their priorities. Table 2.

Although the processor provides a default mapping, the user can alter the mappings and priorities of interrupt events by writing the appropriate values into the interrupt assignment registers (IAR). Table 3 describes the inputs into the SIC and the default mappings into the CEC. Rev. E | Page 7 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 Table 3.

(For more information, see Dynamic Power Management on Page 13.) Because multiple interrupt sources can map to a single generalpurpose interrupt, multiple pulse assertions can occur simultaneously, before or during interrupt processing for an interrupt event already detected on this interrupt input. The IPEND register 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 processor pipeline. At this point the CEC recognizes and queues 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, depending on the activity within and the state of the processor. Event Control The Blackfin processor provides 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 16 bits wide: • CEC interrupt latch register (ILAT) – 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 be written only when its corresponding IMASK bit is cleared. • CEC interrupt mask register (IMASK) – Controls the masking and unmasking of individual events. When a bit is set in the IMASK register, that event is unmasked and is 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. (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 on Page 7. • SIC interrupt mask register (SIC_IMASK) – Controls the masking and unmasking of each peripheral interrupt event. When a bit is set in the register, that peripheral event is unmasked and is processed by the system when asserted. A cleared bit in the register masks the peripheral event, preventing the processor from servicing 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 indicates the peripheral is not asserting the event. DMA CONTROLLERS The Blackfin processors have 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 DMAcapable peripherals. Additionally, 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 and the asynchronous memory controller. DMA-capable peripherals include the Ethernet MAC (ADSP-BF536 and ADSP-BF537 only), SPORTs, SPI port, UARTs, and PPI. Each individual DMA-capable peripheral has at least one dedicated DMA channel. The DMA controller supports both one-dimensional (1-D) and two-dimensional (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 deinterleaved on the fly. Examples of DMA types supported by the DMA controller include • A single, linear buffer that stops upon completion • A circular, auto-refreshing 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.

E | Page 8 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 In addition to the dedicated peripheral DMA channels, there are two memory DMA channels provided for transfers between the various memories of the 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 methodology or by a standard register-based autobuffer mechanism. The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors also have an external DMA controller capability via dual external DMA request pins when used in conjunction with the external bus interface unit (EBIU). This functionality can be used when a high speed interface is required for external FIFOs and high bandwidth communications peripherals such as USB 2.0. It allows control of the number of data transfers for memDMA. The number of transfers per edge is programmable. This feature can be programmed to allow memDMA to have an increased priority on the external bus relative to the core.

External Components for RTC REAL-TIME CLOCK The 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 processor. The RTC peripheral has dedicated power supply pins so that it can remain powered up and clocked even when the rest of the processor is in a low-power state. The RTC provides several programmable interrupt options, including interrupt per second, minute, hour, or day clock ticks, interrupt on programmable stopwatch countdown, or interrupt at a programmed 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 an 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, while the second alarm is for a day and time of that day. 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 the other peripherals, the RTC can wake up the processor from sleep mode upon generation of any RTC wake-up event. Additionally, an RTC wake-up event can wake up the processor from deep sleep mode, and wake up the on-chip internal voltage regulator from the hibernate operating mode. Connect RTC pins RTXI and RTXO with external components as shown in Figure 4. 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 nine general-purpose programmable timer units in the processor. Eight timers have an external pin that can be configured either as a pulse width modulator (PWM) or timer output, as an input to clock the timer, or as a mechanism for measuring pulse widths and periods of external events. These timers can be synchronized to an external clock input to the several other associated PF pins, to an external clock input to the PPI_CLK input pin, or to the internal SCLK. The timer units can be used in conjunction with the two UARTs and the CAN controller to measure the width of the pulses in the data stream to provide a software auto-baud detect function for the respective serial channels. The timers can generate interrupts to the processor core providing periodic events for synchronization, either to the system clock or to a count of external signals. In addition to the eight general-purpose programmable timers, a ninth timer is also provided. This extra timer is clocked by the internal processor clock and is typically used as a system tick clock for generating periodic interrupts in an operating system. WATCHDOG TIMER The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors include 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 system reset, nonmaskable interrupt (NMI), or Rev.

The SPORTs support the following features: • I2S capable operation. • Bidirectional operation – Each SPORT has two sets of independent 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 significant 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 μ-law companding according to ITU recommendation 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. • 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 channels out of a 1024-channel window and is compatible with the H.100, H.110, MVIP-90, and HMVIP standards. port provides a full-duplex, synchronous serial interface, which supports both master/slave modes and multimaster environments. The SPI port’s baud rate and clock phase/polarities are programmable, and it has an integrated DMA controller, configurable to support transmit or receive data streams. The SPI’s DMA controller can only service unidirectional accesses at any given time. The SPI port’s clock rate is calculated as: f SCLK SPI Clock Rate = ----------------------------------2 × 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 sampling of data on the two serial data lines. UART PORTS The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors provide two full-duplex universal asynchronous receiver and transmitter (UART) ports, which are fully compatible with PCstandard UARTs. Each UART port provides a simplified UART interface to other peripherals or hosts, supporting full-duplex, DMA-supported, asynchronous transfers of serial data. A UART port includes support for five to eight data bits, one or two stop bits, and none, even, or odd parity. Each 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 transfers both transmit and receive data. This reduces the number and frequency of interrupts required to transfer 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. Each UART port’s baud rate, serial data format, error code generation and status, and interrupts are programmable: • Supporting bit rates ranging from (fSCLK/1,048,576) to (fSCLK/16) bits per second. • Supporting data formats from 7 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 × UARTx_Divisor Where the 16-bit UARTx_Divisor comes from the UARTx_DLH register (most significant 8 bits) and UARTx_DLL register (least significant 8 bits). SERIAL PERIPHERAL INTERFACE (SPI) PORT The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors have 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 InputSlave Output, MISO) and a clock pin (serial clock, SCK). An SPI chip select input pin (SPISS) lets other SPI devices select the processor, and seven SPI chip select output pins (SPISEL7–1) let the processor select other SPI devices. The SPI select pins are reconfigured programmable flag pins. Using these pins, the SPI Rev. E | Page 10 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 In conjunction with the general-purpose timer functions, autobaud detection is supported. The capabilities of the UARTs are further extended with support for the infrared data association (IrDA®) serial infrared physical layer link specification (SIR) protocol. 10/100 ETHERNET MAC The ADSP-BF536 and ADSP-BF537 processors offer the capability to directly connect to a network by way of an embedded fast Ethernet Media Access Controller (MAC) that supports both 10-BaseT (10 Mbps) and 100-BaseT (100 Mbps) operation. The 10/100 Ethernet MAC peripheral is fully compliant to the IEEE 802.3-2002 standard, and it provides programmable features designed to minimize supervision, bus use, or message processing by the rest of the processor system. Some standard features are • Support of MII and RMII protocols for external PHYs. • Full duplex and half duplex modes. • Data framing and encapsulation: generation and detection of preamble, length padding, and FCS. • Media access management (in half-duplex operation): collision and contention handling, including control of retransmission of collision frames and of back-off timing. • Flow control (in full-duplex operation): generation and detection of PAUSE frames. • Station management: generation of MDC/MDIO frames for read-write access to PHY registers. • SCLK operating range down to 25 MHz (active and sleep operating modes). • Internal loopback from Tx to Rx. Some advanced features are • Buffered crystal output to external PHY for support of a single crystal system. • Automatic checksum computation of IP header and IP payload fields of Rx frames. • Independent 32-bit descriptor-driven Rx and Tx DMA channels. • Frame status delivery to memory via DMA, including frame completion semaphores, for efficient buffer queue management in software. • Tx DMA support for separate descriptors for MAC header and payload to eliminate buffer copy operations. • Convenient frame alignment modes support even 32-bit alignment of encapsulated Rx or Tx IP packet data in memory after the 14-byte MAC header. • Programmable Ethernet event interrupt supports any combination of • Any selected Rx or Tx frame status conditions. • PHY interrupt condition. • Wake-up frame detected. • Any selected MAC management counter(s) at half-full. • DMA descriptor error. • 47 MAC management statistics counters with selectable clear-on-read behavior and programmable interrupts on half maximum value. CONTROLLER AREA NETWORK (CAN) The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors offer a CAN controller that is a communication controller implementing the CAN 2.0B (active) protocol. This protocol is an asynchronous communications protocol used in both industrial and automotive control systems. The CAN protocol is wellsuited for control applications due to its capability to communicate reliably over a network, since the protocol incorporates CRC checking message error tracking, and fault node confinement. The CAN controller offers the following features: • 32 mailboxes (eight receive only, eight transmit only, 16 configurable for receive or transmit). • Dedicated acceptance masks for each mailbox. • Additional data filtering on first two bytes. • Support for both the standard (11-bit) and extended (29-bit) identifier (ID) message formats. • Support for remote frames. • Active or passive network support. • CAN wake-up from hibernation mode (lowest static power consumption mode). • Interrupts, including: Tx complete, Rx complete, error, global. The electrical characteristics of each network connection are very demanding so the CAN interface is typically divided into two parts: a controller and a transceiver. This allows a single controller to support different drivers and CAN networks. The CAN module represents only the controller part of the interface. The controller interface supports connection to 3.3 V highspeed, fault-tolerant, single-wire transceivers. TWI CONTROLLER INTERFACE The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors include a 2-wire interface (TWI) module for providing a simple exchange method of control data between multiple devices. The TWI is compatible with the widely used I2C® bus standard. The TWI module offers the capabilities of simultaneous master and slave operation, support for both 7-bit addressing and multimedia data arbitration. The TWI interface utilizes two pins for transferring clock (SCL) and data (SDA) and supports the protocol at speeds up to 400 kbps. The TWI interface pins are compatible with 5 V logic levels. Additionally, the processor’s TWI module is fully compatible with serial camera control bus (SCCB) functionality for easier control of various CMOS camera sensor devices. Rev. E | Page 11 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 • Programmable Rx address filters, including a 64-bit address hash table for multicast and/or unicast frames, and programmable filter modes for broadcast, multicast, unicast, control, and damaged frames. • Advanced power management supporting unattended transfer of Rx and Tx frames and status to/from external memory via DMA during low power sleep mode. • System wake-up from sleep operating mode upon magic packet or any of four user-definable wake-up frame filters. • Support for 802.3Q tagged VLAN frames. • Programmable MDC clock rate and preamble suppression. • In RMII operation, 7 unused pins may be configured as GPIO pins for other purposes. GPIO pins defined as inputs can be configured to generate hardware interrupts, while output pins can be triggered by software interrupts. • GPIO interrupt sensitivity registers – The two GPIO interrupt sensitivity registers specify whether individual pins are level- or edge-sensitive and specify—if edge-sensitive— 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. PARALLEL PERIPHERAL INTERFACE (PPI) 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, bidirectional data transfer with up to 16 bits of data. Up to three frame synchronization signals are also provided. In ITU-R 656 mode, the PPI provides half-duplex bidirectional transfer of 8- or 10-bit video data. Additionally, on-chip decode of embedded start-of-line (SOL) and start-offield (SOF) preamble packets is supported. PORTS The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors group the many peripheral signals to four ports—Port F, Port G, Port H, and Port J. Most of the associated pins are shared by multiple signals. The ports function as multiplexer controls. Eight of the pins (Port F7–0) offer high source/high sink current capabilities. General-Purpose I/O (GPIO) The processors have 48 bidirectional, general-purpose I/O (GPIO) pins allocated across three separate GPIO modules— PORTFIO, PORTGIO, and PORTHIO, associated with Port F, Port G, and Port H, respectively. Port J does not provide GPIO functionality. Each GPIO-capable pin shares functionality with other processor peripherals via a multiplexing scheme; however, the GPIO functionality is the default state of the device upon power-up. Neither GPIO output or input drivers are active by default. Each general-purpose port pin can be individually controlled by manipulation of the port control, status, and interrupt registers: • GPIO direction control register – Specifies the direction of each individual GPIO pin as input or output. • GPIO control and status registers – The processors employ 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 pin values, one register is written in order to clear pin values, one register is written in order to toggle pin values, and one register is written in order to specify a pin value. Reading the GPIO status register allows software to interrogate the sense of the pins. • GPIO interrupt mask registers – The two GPIO interrupt mask registers allow each individual GPIO pin to function as an interrupt to the processor. Similar to the two GPIO control registers that are used to set and clear individual 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. 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: 1. Input mode – Frame syncs and data are inputs into the PPI. 2. Frame capture mode – Frame syncs are outputs from the PPI, but data are inputs. 3. Output mode – Frame syncs and data are outputs from the PPI. 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. Rev. E | Page 12 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 Frame Capture Mode Frame capture mode allows the video source(s) to act as a slave (for frame capture for example). The ADSP-BF534/ ADSP-BF536/ADSP-BF537 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 hardware signaling. 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 performance can be achieved. The processor core and all enabled peripherals run at full speed. 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. 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 applications. Three distinct submodes are supported: 1. Active video only mode 2. Vertical blanking only mode 3. Entire field mode Active Video Mode Active video only mode is used when only the active video portion 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). 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 vertical 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. 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. Typically an external event or RTC activity wakes up the processor. When in the sleep mode, asserting wake-up causes the processor to sense the value of the BYPASS bit in the PLL control register (PLL_CTL). If BYPASS is disabled, the processor transitions to the full on mode. If BYPASS is enabled, the processor transitions to the active mode. System DMA access to L1 memory is not supported in sleep mode. Table 4. Power Settings PLL PLL Bypassed Enabled No Enabled/ Yes Disabled Enabled — Disabled — — Core Clock (CCLK) Enabled Enabled System Clock (SCLK) Enabled Enabled Internal Power (VDDINT) On On Mode Full On Active Sleep Deep Sleep Hibernate Disabled Disabled Enabled On Disabled Disabled On Disabled Disabled Off DYNAMIC POWER MANAGEMENT The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors provide five operating modes, each with a different performance and power profile. In addition, dynamic power management provides the control functions to dynamically alter the processor core supply voltage, further reducing power dissipation. Control of clocking to each of the peripherals also reduces power consumption. See Table 4 for a summary of the power settings for each mode. Also, see Table 15, Table 16 and Table 17. Rev. E | Deep Sleep Operating Mode—Maximum Dynamic Power Savings The deep sleep mode maximizes dynamic power savings by disabling the clocks to the processor core (CCLK) and to all synchronous peripherals (SCLK). Asynchronous peripherals, such as the RTC, may still be running but cannot access internal resources or external memory. This powered-down 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 interrupt causes the Page 13 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 processor to transition to the active mode. Assertion of RESET while in deep sleep mode causes the processor to transition to the full-on mode. reduction in power dissipation, while reducing the voltage by 25% reduces 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, as shown in the following equations. The power savings factor (PSF) is calculated as: V DDINTRED 2 f CCLKRED T RED PSF = -------------------- × ⎛ ------------------------- ⎞ × ⎛ ------------ ⎞ f CCLKNOM ⎝ V DDINTNOM⎠ ⎝ T NOM ⎠ where: 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 – PSF ) × 100 % 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 of the synchronous peripherals (SCLK). The internal voltage regulator for the processor can be shut off by writing b#00 to the FREQ bits of the VR_CTL register. This disables both CCLK and SCLK. Furthermore, it sets the internal power supply voltage (VDDINT) to 0 V to provide the greatest power savings. To preserve the processor state, prior to removing power, any critical information stored internally (memory contents, register contents, etc.) must be written to a nonvolatile storage device. Since VDDEXT is still supplied in this mode, all of the external pins three-state, unless otherwise specified. This allows other devices that are connected to the processor to still have power applied without drawing unwanted current. The Ethernet or CAN modules can wake up the internal supply regulator. If the PH6 pin does not connect as PHYINT signal to an external PHY device, it can be pulled low by any other device to wake the processor up. The regulator can also be woken up by a real-time clock wake-up event or by asserting the RESET pin. All hibernate wake-up events initiate the hardware reset sequence. Individual sources are enabled by the VR_CTL register. With the exception of the VR_CTL and the RTC registers, all internal registers and memories lose their content in the hibernate state. State variables may be held in external SRAM or SDRAM. The SCKELOW bit in the VR_CTL register controls whether SDRAM operates in self-refresh mode which allows it to retain its content while the processor is in reset. VOLTAGE REGULATION The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors provide an on-chip voltage regulator that can generate appropriate VDDINT voltage levels from the VDDEXT supply. See Operating Conditions on Page 23 for regulator tolerances and acceptable VDDEXT ranges for specific models. Figure 5 shows the typical external components required to complete the power management system. The regulator controls 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 supplied. While in hibernate mode, VDDEXT can still be applied, eliminating the need for external buffers. The voltage regulator can be activated from this power-down state by asserting the RESET pin, which then initiates a boot sequence. The regulator can also be disabled and bypassed at the user’s discretion. For additional information on voltage regulation, see Switching Regulator Design Considerations for the ADSP-BF533 Blackfin Processors (EE-228). Power Savings As shown in Table 5, the processors support three different power domains which maximizes flexibility, 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 management, 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 The dynamic power management feature allows both the processor’s input voltage (VDDINT) and clock frequency (fCCLK) to be dynamically controlled. The power dissipated by a processor is largely a function of its clock frequency and the square of the operating voltage. For example, reducing the clock frequency by 25% results in a 25% Rev.

Voltage Regulator Circuit CLOCK SIGNALS The ADSP-BF534/ADSP-BF536/ADSP-BF537 processors 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 specified 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 processors include an on-chip oscillator circuit, an external crystal may be used. For fundamental frequency operation, use the circuit shown in Figure 6. 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 kΩ range. Further parallel resistors are typically not recommended. The two capacitors and the series resistor shown in Figure 6 fine-tune phase and amplitude of the sine frequency. The capacitor and resistor values shown in Figure 6 are typical values only. The capacitor values are dependent upon the crystal manufacturers’ load capacitance recommendations and the PCB physical layout. The resistor value depends on the drive level specified by the crystal manufacturer. The user should verify the customized values based on careful investigations of multiple devices over temperature range. A third-overtone crystal can be used for 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 6. A design procedure for third-overtone operation is discussed in detail in the application note Using Third Overtone Crystals with the ADSP-218x DSP (EE-168). The CLKBUF pin is an output pin, and is a buffer version of the input clock. This pin is particularly useful in Ethernet applications to limit the number of required clock sources in the system. In this type of application, a single 25 MHz or 50 MHz crystal may be applied directly to the processors. The 25 MHz or 50 MHz output of CLKBUF can then be connected to an external Ethernet MII or RMII PHY device. Because of the default 10× PLL multiplier, providing a 50 MHz CLKIN exceeds the recommended operating conditions of the lower speed grades. Because of this restriction, an RMII PHY requiring a 50 MHz clock input cannot be clocked directly from the CLKBUF pin for the lower speed grades. In this case, either provide a separate 50 MHz clock source, or use an RMII PHY with 25 MHz clock input options. The CLKBUF output is active by default and can be disabled using the VR_CTL register for power savings. The Blackfin core runs at a different clock rate than the on-chip peripherals. As shown in Figure 7, 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 programmable 0.5× to 64× multiplication factor (bounded by specified minimum and maximum VCO frequencies). The default multiplier is 10×, but it can be modified by a software instruction sequence in the PLL_CTL register. On-the-fly CCLK and SCLK frequency changes can be effected by simply writing to the PLL_DIV register. Whereas the maximum allowed CCLK and SCLK rates depend on the applied voltages VDDINT and VDDEXT, the VCO is always permitted to run up to the frequency specified by the part’s speed grade. The CLKOUT pin reflects the SCLK frequency to the off-chip world. It belongs to the SDRAM interface, but it functions as reference signal in other timing specifications as well. While active by default, it can be disabled using the EBIU_SDGCTL and EBIU_AMGCTL registers. 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. Rev. E | Page 15 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 Table 8.

The SSEL value can be changed dynamically without any PLL lock latencies by writing the appropriate values to the PLL divisor register (PLL_DIV). Table 6. Example System Clock Ratios Example Frequency Ratios (MHz) VCO SCLK 100 100 300 50 500 50 The BMODE pins of the reset configuration register, sampled during power-on resets and software-initiated resets, implement the following modes: • Execute from 16-bit external memory – Execution starts from address 0x2000 0000 with 16-bit packing. 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 and 16-bit external flash memory – The 8-bit or 16-bit flash boot routine located in Boot ROM memory space is set up using asynchronous memory bank 0. All configuration settings are set for the slowest device possible (3-cycle hold time; 15-cycle R/W access times; 4-cycle setup). The Boot ROM evaluates the first byte of the boot stream at address 0x2000 0000. If it is 0x40, 8-bit boot is performed. A 0x60 byte assumes a 16-bit memory device and performs 8-bit DMA. A 0x20 byte also assumes 16-bit memory but performs 16-bit DMA. • Boot from serial SPI memory (EEPROM or flash) – 8-, 16-, or 24-bit addressable devices are supported as well as AT45DB041, AT45DB081, AT45DB161, AT45DB321, AT45DB642, and AT45DB1282 DataFlash® devices from Atmel. The SPI uses the PF10/SPI SSEL1 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 24-bit, or Atmel addressable device is detected, and begins clocking data into the processor. • Boot from SPI host device – The Blackfin processor operates in SPI slave mode and is configured to receive the bytes of the .LDR file from an SPI host (master) agent. 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 flag is chosen by the user and this information is transferred to the Blackfin processor via bits 10:5 of the FLAG header. • Boot from UART – Using an autobaud handshake sequence, a boot-stream-formatted program is downloaded by the host. The host agent selects a baud rate within the UART’s clocking capabilities. When performing the autobaud, the UART expects an “@” (boot stream) character Signal Name SSEL3–0 0001 0110 1010 Divider Ratio VCO/SCLK 1:1 6:1 10:1 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. Core Clock Ratios Example Frequency Ratios (MHz) VCO CCLK 300 300 300 150 500 125 200 25 Signal Name CSEL1–0 00 01 10 11 Divider Ratio VCO/CCLK 1:1 2:1 4:1 8:1 The maximum CCLK frequency not only depends on the part’s speed grade (see Ordering Guide on Page 67), it also depends on the applied VDDINT voltage (see Table 10, Table 11, and Table 12 on Page 24 for details). The maximal system clock rate (SCLK) depends on the chip package and the applied VDDEXT voltage (see Table 14 on Page 24). BOOTING MODES The ADSP-BF534/ADSP-BF536/ADSP-BF537 processor has six mechanisms (listed in Table 8) for automatically loading internal and external memory after a reset. A seventh mode is provided to execute from external memory, bypassing the boot Rev. E | Page 16 of 68 | March 2008 ADSP-BF534/ADSP-BF536/ADSP-BF537 (8 bits data, 1 start bit, 1 stop bit, no parity bit) on the RXD pin to determine the bit rate. It then replies with an acknowledgement that is composed of 4 bytes: 0xBF, the value of UART_DLL, the value of UART_DLH, and 0x00. The host can then download the boot stream. When the processor needs to hold off the host, it deasserts CTS. Therefore, the host must monitor this signal. • Boot from serial TWI memory (EEPROM/flash) – The Blackfin processor operates in master mode and selects the TWI slave with the unique ID 0xA0. It submits successive read commands to the memory device starting at 2-byte internal address 0x0000 and begins clocking data into the processor. The TWI memory device should comply with Philips I2C Bus Specification version 2.1 and have the capability to auto-increment its internal address counter such that the contents of the memory device can be read sequentially. • Boot from TWI host – The TWI host agent selects the slave with the unique ID 0x5F. The processor replies with an acknowledgement and the host can then download the boot stream. The TWI host agent should comply with Philips I2C Bus Specification version 2.1. An I2C multiplexer can be used to select one processor at a time when booting multiple processors from a single TWI. For each of the boot modes, a 10-byte header is first brought in from an external 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. To augment the boot modes, a secondary software loader can be added to provide additional booting mechanisms. This secondary loader could provide the capability to boot from flash, variable baud rate, and other sources. In all boot modes except bypass, program execution starts from on-chip L1 memory address 0xFFA0 0000. The assembly language, which takes advantage of the processor’s unique architecture, offers the following advantages: • Seamlessly integrated DSP/MCU 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 programming model. • 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 Blackfin processors are supported with a complete set of CROSSCORE®† software and hardware development tools, including Analog Devices emulators and the VisualDSP++®‡ development environment. The same emulator hardware that supports other Analog Devices processors also fully emulates the Blackfin processor family. The VisualDSP++ project management environment lets programmers develop and debug an application. This environment includes an easy to use assembler that is based on an algebraic 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 Blackfin assembly. The Blackfin processor has architectural features that improve the efficiency of compiled C/C++ code. The VisualDSP++ debugger has a number of important features. Data visualization is enhanced by a plotting package that offers a significant level of flexibility. This graphical representation of user data enables the programmer to quickly determine the performance of an algorithm. As algorithms grow in complexity, 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 passively gather important code execution metrics without interrupting the real-time characteristics of the program. Essentially, the developer can identify bottlenecks in software quickly and effi- 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 provide 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 programmer 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 compiling 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 operation, allowing multiple levels of access to core processor resources. † ‡ CROSSCORE is a registered trademark of Analog Devices, Inc.

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. • 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++ IDE lets programmers define and manage software development. Its dialog boxes and property pages let programmers configure and manage all development tools, including color syntax highlighting in the VisualDSP++ editor. These capabilities permit 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 memory and timing constraints of embedded, real-time 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 with 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 generation of various VDK-based objects, and visualizing the system state when debugging an application that uses the VDK. The expert linker can be used to visually manipulate the placement of code and data in the embedded system. Memory utilization can be viewed in a color-coded graphical form. Code and data can be easily moved to different areas of the processor or external memory with the drag of the mouse. Runtime stack and heap usage can be examined. The expert linker is fully compatible with existing linker definition 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 Blackfin to monitor and control the target board processor during emulation. The emulator provides full-speed emulation, allowing inspection and modification of memory, registers, and processor 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. Third party software tools include DSP libraries, real-time operating systems, and block diagram design tools. EZ-KIT Lite® Evaluation Board For evaluation of ADSP-BF534/ADSP-BF536/ADSP-BF537 processors, use the ADSP-BF537 EZ-KIT Lite board available from Analog Devices. Order part number ADDS-BF537-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 system developer needs in order 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, allowing the developer to load code, set breakpoints, observe variables, observe memory, and examine registers. The processor 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. For details on target board design issues including mechanical layout, single processor connections, multiprocessor scan chains, signal buffering, signal termination, and emulator pod logic, see Analog Devices JTAG Emulation Technical Reference (EE-68) on the Analog Devices website under www.analog.com/ee-notes. This document is updated regularly to keep pace with improvements to emulator support.

In order to maintain maximum functionality and reduce package size and pin count, some pins have dual, multiplexed functions. In cases where pin function is reconfigurable, the default state is shown in plain text, while the alternate function is shown in italics. Pins shown with an asterisk after their name (*) offer high source/high sink current capabilities. All pins are three-stated during and immediately after reset, with the exception of the external memory interface, asynchronous and synchronous memory control, and the buffered XTAL output pin (CLKBUF).

All I/O pins have their input buffers disabled with the exception of the pins noted in the data sheet that need pull-ups or pulldowns if unused. The SDA (serial data) and SCL (serial clock) pins are open drain and therefore require a pull-up resistor. Consult version 2.1 of the I2C specification for the proper resistor value. Rev.

All topics discussed in this section are described in detail in EE-297. Total power dissipation has two components: 1. Static, including leakage current 2. Dynamic, due to transistor switching characteristics Many operating conditions can also affect power dissipation, including temperature, voltage, operating frequency, and processor activity. Electrical Characteristics on Page 25 shows the Table 15.

IDDDEEPSLEEP specifies static power dissipation as a function of voltage (VDDINT) and temperature (see Table 15 or Table 16), and IDDINT specifies the total power specification for the listed test conditions, including the dynamic component as a function of voltage (VDDINT) and frequency (Table 18). The dynamic component is also subject to an Activity Scaling Factor (ASF) which represents application code running on the processor (Table 17). 0.85 V 3.20 7.80 13.50 19.00 27.80 41.30 58.30 82.30 91.20 111.80 123.60 0.90 V 3.70 8.40 14.80 20.60 30.90 44.80 63.70 88.50 98.20 120.30 132.20 0.95 V 4.50 9.90 16.40 22.90 33.70 48.90 69.00 95.80 106.00 127.60 141.90 1.00 V 5.50 10.90 18.20 25.90 37.30 53.90 75.90 104.00 114.20 138.00 152.30 1.05 V 6.60 12.30 19.90 28.20 41.40 58.60 82.90 112.50 123.00 148.50 163.70 Voltage (VDDINT) 1.10 V 1.15 V 7.90 9.30 13.80 15.50 22.70 25.60 31.60 34.90 44.80 50.00 63.90 69.70 90.50 98.40 121.80 130.60 132.40 143.30 159.60 171.40 175.60 189.30 1.20 V 10.50 17.50 28.40 38.90 54.80 76.90 106.40 141.30 155.00 184.60 202.80 1.25 V 12.50 19.60 31.80 42.90 59.40 84.00 115.30 153.20 167.40 198.80 217.70 1.30 V 13.90 21.70 35.70 47.60 66.10 92.20 124.60 164.80 179.80 213.40 232.30 1.32 V 14.80 23.11 37.21 49.50 68.40 94.98 128.12 169.73 185.43 219.66 238.65 1.35 V 16.10 25.40 39.60 52.50 72.00 99.30 133.60 177.40 194.20 229.40 248.50 1.40 V 18.20 28.40 43.60 58.20 79.90 108.40 144.70 191.90 209.20 244.90 266.20 Values are guaranteed maximum IDDDEEPSLEEP specifications for 300 MHz and 400 MHz speed-grade devices.

Time tTRIP is the interval from when the output starts driving to when the output reaches the 1.0 V or 2.0 V 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 measurement value is that of the first pin to start driving. - 30 V OL - 40 - 50 - 60 Output Disable Time 0 0.5 1.0 1.5 2.0 2.5 3.0 SOURCE VOLTAGE (V) Figure 44.

The time for the voltage on the bus to decay by ΔV is dependent on the capacitive load, CL, and the load current, IL. This decay time can be approximated by the equation: t DECAY = ( C L ΔV ) ⁄ I L The output disable time tDIS is the difference between tDIS_MEASURED and tDECAY as shown in Figure 46. The time tDIS_MEASURED is the interval from when the reference signal switches to when the output voltage decays ΔV from the measured output-high or output-low voltage. The time tDECAY is calculated with the test loads CL and IL, and with ΔV equal to 0.5 V.
