The Blackfin processor combines a dualMAC 16-bit 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. New enhancements to the Blackfin+ core add 32-bit MAC and 16-bit complex MAC support, cache enhancements, branch prediction and other instruction set improvements—all while maintaining instruction set compatibility to previous Blackfin products. The processor offers performance up to 400 MHz, as well as low static power consumption. Produced with a low-power and lowvoltage design methodology, they provide world-class power management and performance. By integrating a rich set of industry-leading system peripherals and memory (shown in Table 1), the Blackfin processor is the platform of choice for next-generation applications that require RISC-like programmability, multimedia support, and leadingedge signal processing in one integrated package. These applications span a wide array of markets, from automotive systems to embedded industrial, instrumentation, video/image analysis, biometric and power/motor control applications. Table 1.

The core, shown in Figure 2, contains two 16-bit multipliers, one 32-bit multiplier, two 40-bit accumulators (which may be used together as a 72-bit accumulator), two  40-bit ALUs, one 72-bit ALU, four video ALUs, and a 40-bit shifter. The computation units process 8-, 16-, or 32-bit data from the register file. 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, 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. 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. 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 a second ALU is used, quad 16-bit operations are possible. The core can perform two 16-bit by 16-bit multiply-accumulates or one 32-bit multiply-accumulate in each cycle. Signed and unsigned formats, rounding, saturation, and complex multiplies are supported. The 40-bit shifter can perform shifts and rotates and is used to support normalization, field extract, and field deposit instructions.

For program flow control, the sequencer supports PC relative and indirect conditional jumps (with dynamic branch prediction), and subroutine calls. Hardware supports zero-overhead 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 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). The Blackfin processor supports 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 data memory holds 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. INSTRUCTION SET DESCRIPTION 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. The Blackfin processor supports 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 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. Rev. D | Page 5 of 114 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. • Control of all asynchronous and synchronous events to the processor is handled by two subsystems: the core event controller (CEC) and the system event controller (SEC). • 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. PROCESSOR INFRASTRUCTURE The following sections provide information on the primary infrastructure components of the ADSP-BF70x processor. DMA Controllers The processor uses direct memory access (DMA) to transfer data within memory spaces or between a memory space and a peripheral. The processor can specify data transfer operations and return to normal processing while the fully integrated DMA controller carries out the data transfers independent of processor activity. DMA transfers can occur between memory and a peripheral or between one memory and another memory. Each memory-tomemory DMA stream uses two channels, where one channel is the source channel, and the second is the destination channel. All DMAs can transport data to and from all on-chip and offchip memories. Programs can use two types of DMA transfers, descriptor-based or register-based. Register-based DMA allows the processor to directly program DMA control registers to initiate a DMA transfer. On completion, the control registers may be automatically updated with their original setup values for continuous transfer. Descriptor-based DMA transfers require a set of parameters stored within memory to initiate a DMA sequence. Descriptor-based DMA transfers allow multiple DMA sequences to be chained together and a DMA channel can be programmed to automatically set up and start another DMA transfer after the current sequence completes. The DMA controller supports the following DMA operations. • A single linear buffer that stops on completion. • A linear buffer with negative, positive, or zero stride length. • A circular, auto-refreshing buffer that interrupts when each buffer becomes full. | February 2019 ADSP-BF700/701/702/703/704/705/706/707 • A similar buffer that interrupts on fractional buffers (for example, 1/2, 1/4). • 1D DMA—uses a set of identical ping-pong buffers defined by a linked ring of two-word descriptor sets, each containing a link pointer and an address. • 1D DMA—uses a linked list of 4 word descriptor sets containing a link pointer, an address, a length, and a configuration. • 2D DMA—uses an array of one-word descriptor sets, specifying only the base DMA address. • 2D DMA—uses a linked list of multi-word descriptor sets, specifying everything. Trigger Routing Unit (TRU) The TRU provides system-level sequence control without core intervention. The TRU maps trigger masters (generators of triggers) to trigger slaves (receivers of triggers). Slave endpoints can be configured to respond to triggers in various ways. Common applications enabled by the TRU include: • Automatically triggering the start of a DMA sequence after a sequence from another DMA channel completes • Software triggering • Synchronization of concurrent activities General-Purpose I/O (GPIO) Each general-purpose port pin can be individually controlled by manipulation of the port control, status, and interrupt registers: Event Handling The 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 processor 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 through the JTAG interface. • Reset—This event resets the processor. • Nonmaskable interrupt (NMI)—The NMI event can be generated either by the software watchdog timer, by the NMI input signal to the processor, or by software. 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 signals, timers, and other peripherals, as well as by an explicit software instruction. System Event Controller (SEC) The SEC manages the enabling, prioritization, and routing of events from each system interrupt or fault source. Additionally, it provides notification and identification of the highest priority active system interrupt request to the core and routes system fault sources to its integrated fault management unit. The SEC triggers core general-purpose interrupt IVG11. It is recommended that IVG11 be set to allow self-nesting. The four lower priority interrupts (IVG15-12) may be used for software interrupts. • GPIO direction control register—Specifies the direction of each individual GPIO pin as input or output. • GPIO control and status registers—A write one to modify mechanism allows any combination of individual GPIO pins to be modified in a single instruction, without affecting the level of any other GPIO pins. • GPIO interrupt mask registers—Allow each individual GPIO pin to function as an interrupt to the processor. 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—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. Pin Interrupts Every port pin on the processor can request interrupts in either an edge-sensitive or a level-sensitive manner with programmable polarity. Interrupt functionality is decoupled from GPIO operation. Three system-level interrupt channels (PINT0–3) are reserved for this purpose. Each of these interrupt channels can manage up to 32 interrupt pins. The assignment from pin to interrupt is not performed on a pin-by-pin basis. Rather, groups of eight pins (half ports) can be flexibly assigned to interrupt channels. Every pin interrupt channel features a special set of 32-bit memory-mapped registers that enable half-port assignment and interrupt management. This includes masking, identification, and clearing of requests. These registers also enable access to the respective pin states and use of the interrupt latches, regardless of whether the interrupt is masked or not. Most control registers feature multiple MMR address entries to write-one-to-set or write-one-to-clear them individually. Pin Multiplexing The processor supports a flexible multiplexing scheme that multiplexes the GPIO pins with various peripherals. A maximum of 4 peripherals plus GPIO functionality is shared by each GPIO pin. All GPIO pins have a bypass path feature—that is, when the Rev.

All L1 memory is protected by a multi-parity-bit concept, regardless of whether the memory is operating in SRAM or cache mode. Outside of the L1 domain, L2 and L3 memories are arranged using a Von Neumann topology. The L2 memory domain is a unified instruction and data memory and can hold any mixture of code and data required by the system design. The L2 memory domain is accessible by the Blackfin+ core through a dedicated 64-bit interface. It operates at SYSCLK frequency. The processor features up to 1M byte of L2 SRAM, which is ECC-protected and organized in eight banks. Individual banks can be made private to any system master.

The modified Harvard architecture supports two concurrent 32-bit data accesses along with an instruction fetch at full processor speed which provides high-bandwidth processor performance. In the core, a 64K byte block of data memory partners with an 64K byte memory block for instruction storage. Each data block is multibanked for efficient data exchange through DMA and can be configured as SRAM. Alternatively, 16K bytes of each block can be configured in L1 cache mode. The four-way set-associative instruction cache and the 2 two-way set-associative data caches greatly accelerate memory access performance, especially when accessing external memories. 0x 7000 0000 - L1 Instruction The L1 memory system is the highest-performance memory available to the Blackfin+ processor core.

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 core-accessible memory as cache or SRAM, and larger, lower-cost and performance interface-accessible memory systems.

ADSP-BF706/ADSP-BF707 Internal/External Memory Map | February 2019 ADSP-BF700/701/702/703/704/705/706/707 Static Memory Controller (SMC) The SMC can be programmed to control up to two blocks of external memories or memory-mapped devices, with very flexible timing parameters. Each block occupies a 8K byte segment regardless of the size of the device used. The following hardware-accelerated cryptographic ciphers are supported: • AES in ECB, CBC, ICM, and CTR modes with 128-, 192-, and 256-bit keys • DES in ECB and CBC mode with 56-bit key • 3DES in ECB and CBC mode with 3x 56-bit key Dynamic Memory Controller (DMC) The DMC includes a controller that supports JESD79-2E compatible double-data-rate (DDR2) SDRAM and JESD209A lowpower DDR (LPDDR) SDRAM devices. The DMC PHY features on-die termination on all data and data strobe pins that can be used during reads. The following hardware-accelerated hash functions are supported: • SHA-1 • SHA-2 with 224-bit and 256-bit digest • HMAC transforms for SHA-1 and SHA-2 I/O Memory Space The processor does not define a separate I/O space. All resources are mapped through the flat 32-bit address space. Onchip I/O devices have their control registers mapped into memory-mapped registers (MMRs) at addresses in a region 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 on-chip peripherals outside of the core. The MMRs are accessible only in supervisor mode and appear as reserved space to on-chip peripherals. Booting Public key accelerator is available to offload computation-intensive public key cryptography operations. Both a hardware-based nondeterministic random number generator and pseudo-random number generator are available. The TRNG also provides HW post-processing to meet NIST requirements of FIPS 140-2, while the PRNG is ANSI X9.31 compliant. Secure boot is also available with 224-bit elliptic curve digital signatures ensuring integrity and authenticity of the boot stream. Optionally, confidentiality is also ensured through AES128 encryption. The processor has several mechanisms for automatically loading internal and external memory after a reset. The boot mode is defined by the SYS_BMODE input pins dedicated for this purpose. There are two categories of boot modes. In master boot mode, the processor actively loads data from serial memories. In slave boot modes, the processor receives data from external host devices. The boot modes are shown in Table 2. These modes are implemented by the SYS_BMODE bits of the reset configuration register and are sampled during power-on resets and softwareinitiated resets. Table 2. Boot Modes SYS_BMODE Setting 00 01 10 11 CAUTION This product includes security features that can be used to protect embedded nonvolatile memory contents and prevent execution of unauthorized code. When security is enabled on this device (either by the ordering party or the subsequent receiving parties), the ability of Analog Devices to conduct failure analysis on returned devices is limited. Contact Analog Devices for details on the failure analysis limitations for this device. Secure debug is also employed to allow only trusted users to access the system with debug tools.

Rev.

However, Analog Devices does not guarantee that this technology provides absolute security.

While the level of safety is mainly dominated by the system concept, the following primitives are provided by the devices to build a robust safety concept. Multi-Parity-Bit-Protected L1 Memories In the processor’s L1 memory space, whether SRAM or cache, each word is protected by multiple parity bits to detect the single event upsets that occur in all RAMs. This applies both to L1 instruction and data memory spaces. ECC-Protected L2 Memories Error correcting codes (ECC) are used to correct single event upsets. The L2 memory is protected with a single error correctdouble error detect (SEC-DED) code. By default ECC is enabled, but it can be disabled on a per-bank basis. Single-bit errors are transparently corrected. Dual-bit errors can issue a system event or fault if enabled. ECC protection is fully transparent to the user, even if L2 memory is read or written by 8-bit or 16-bit entities. CRC-Protected Memories Synonymously, the system memory protection unit (SMPU) provides memory protection against read and/or write transactions to defined regions of memory. There are two SMPU units in the ADSP-BF70x processors. One is for the L2 memory and the other is for the external DDR memory. The SMPU is also part of the security infrastructure. It allows the user to not only protect against arbitrary read and/or write transactions, but it also allows regions of memory to be defined as secure and prevent non-secure masters from accessing those memory regions. Watchpoint Protection The primary purpose of watchpoints and hardware breakpoints is to serve emulator needs. When enabled, they signal an emulator event whenever user-defined system resources are accessed or the core executes from user-defined addresses. Watchpoint events can be configured such that they signal the events to the fault management unit of the SEC. Watchdog The on-chip software watchdog timer can supervise the Blackfin+ core. Bandwidth Monitor While parity bit and ECC protection mainly protect against random soft errors in L1 and L2 memory cells, the CRC engines can be used to protect against systematic errors (pointer errors) and static content (instruction code) of L1, L2, and even L3 memories (DDR2, LPDDR). The processor features two CRC engines which are embedded in the memory-to-memory DMA controllers. CRC checksums can be calculated or compared on the fly during memory transfers, or one or multiple memory regions can be continuously scrubbed by a single DMA work unit as per DMA descriptor chain instructions. The CRC engine also protects data loaded during the boot process. Memory Protection The Blackfin+ core features a memory protection concept, which grants data and/or instruction accesses to enabled memory regions only. A supervisor mode vs. user mode programming model supports dynamically varying access rights. Increased flexibility in memory page size options supports a simple method of static memory partitioning. System Protection Memory-to-memory DMA channels are equipped with a bandwidth monitor mechanism. They can signal a system event or fault when transactions tend to starve because system buses are fully loaded with higher-priority traffic. Signal Watchdogs The eight general-purpose timers feature modes to monitor offchip signals. The watchdog period mode monitors whether external signals toggle with a period within an expected range. The watchdog width mode monitors whether the pulse widths of external signals are within an expected range. Both modes help to detect undesired toggling (or lack thereof) of  system-level signals. Up/Down Count Mismatch Detection The GP counter can monitor external signal pairs, such as request/grant strobes. If the edge count mismatch exceeds the expected range, the GP counter can flag this to the processor or to the fault management unit of the SEC. Fault Management The system protection unit (SPU) guards against accidental or unwanted access to the MMR space of a peripheral by providing a write-protection mechanism. The user is able to choose and configure the peripherals that are protected as well as configure which ones of the four system MMR masters (core, memory DMA, the SPI host port, and Coresight debug) the peripherals are guarded against. The SPU is also part of the security infrastructure. Along with providing write-protection functionality, the SPU is employed to define which resources in the system are secure or non-secure and to block access to secure resources from non-secure masters. Rev. D | Page 9 of 114 The fault management unit is part of the system event controller (SEC). Any system event, whether a dual-bit uncorrectable ECC error, or any peripheral status interrupt, can be defined as being a fault. Additionally, the system events can be defined as an interrupt to the core. If defined as such, the SEC forwards the event to the fault management unit, which may automatically reset the entire device for reboot, or simply toggle the  SYS_FAULT output pin to signal off-chip hardware. Optionally, the fault management unit can delay the action taken through a keyed sequence, to provide a final chance for the Blackfin+ core to resolve the issue and to prevent the fault action from being taken. | February 2019 ADSP-BF700/701/702/703/704/705/706/707 ADDITIONAL PROCESSOR PERIPHERALS The processor contains a rich set of peripherals connected to the core through several high-bandwidth buses, providing flexibility in system configuration as well as excellent overall system performance (see the block diagram on Page 1). The processor contains 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. The following sections describe additional peripherals that were not previously described. Timers The processor includes several timers which are described in the following sections. General-Purpose Timers There is one GP timer unit, and it provides eight general-purpose programmable timers. Each timer has 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 on the TIMER_TMRx pins, an external TIMER_CLK input pin, or to the internal SCLK0. These timer units can be used in conjunction with the 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 GP timers can generate interrupts to the processor core, providing periodic events for synchronization to either the system clock or to external signals. Timer events can also trigger other peripherals through the TRU (for instance, to signal a fault). Each timer may also be started and/or stopped by any TRU master without core intervention. Core Timer The processor core also has its own dedicated timer. This extra timer is clocked by the internal processor clock and is typically used as a system tick clock for generating periodic operating system interrupts. Watchdog Timer The core includes a 32-bit timer, which may 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 down to zero from the programmed value. This protects the system from remaining in an unknown state where software that would normally reset the timer has stopped running due to an external noise condition or software error. After a reset, software can determine if the watchdog was the source of the hardware reset by interrogating a status bit in its timer control register that is set only upon a watchdog-generated reset. Serial Ports (SPORTs) Two synchronous serial ports (comprised of four half-SPORTs) provide an inexpensive interface to a wide variety of digital and mixed-signal peripheral devices such as Analog Devices’ audio codecs, ADCs, and DACs. Each half-SPORT is made up of two data lines, a clock, and frame sync. The data lines can be programmed to either transmit or receive and each data line has a dedicated DMA channel. Serial port data can be automatically transferred to and from on-chip memory/external memory through dedicated DMA channels. Each of the serial ports can work in conjunction with another serial port to provide TDM support. In this configuration, one SPORT provides two transmit signals while the other SPORT provides the two receive signals. The frame sync and clock are shared. Serial ports operate in six modes: • Standard DSP serial mode • Multichannel (TDM) mode • I2S mode • Packed I2S mode • Left-justified mode • Right-justified mode General-Purpose Counters A 32-bit counter is provided that can operate in general-purpose up/down count modes and can sense 2-bit quadrature or binary codes as typically emitted by industrial drives or manual thumbwheels. Count direction is either controlled by a levelsensitive input pin or by two edge detectors. A third counter input can provide flexible zero marker support and can alternatively be used to input the push-button signal of thumbwheel devices. All three pins have a programmable debouncing circuit. Internal signals forwarded to a GP timer enable this timer to measure the intervals between count events. Boundary registers enable auto-zero operation or simple system warning by interrupts when programmed count values are exceeded. Parallel Peripheral Interface (PPI) The processor provides a parallel peripheral interface (PPI) that supports data widths up to 18 bits. The PPI supports direct connection to TFT LCD panels, parallel analog-to-digital and digital-to-analog converters, video encoders and decoders, image sensor modules, and other general-purpose peripherals. Rev. D | Page 10 of 114 | February 2019 ADSP-BF700/701/702/703/704/705/706/707 The following features are supported in the PPI module: • Programmable data length: 8 bits, 10 bits, 12 bits, 14 bits, 16 bits, and 18 bits per clock. memory-mapped resources of the processor through a SPI SRAM/FLASH style protocol. The following features are included: • Various framed, non-framed, and general-purpose operating modes. Frame syncs can be generated internally or can be supplied by an external device. • Direct read/write of memory and memory-mapped registers • ITU-656 status word error detection and correction for ITU-656 receive modes and ITU-656 preamble and status word decode. • Support for SPI controllers that implement hardwarebased SPI memory protocol • Optional packing and unpacking of data to/from 32 bits from/to 8 bits, 16 bits and 24 bits. If packing/unpacking is enabled, endianness can be configured to change the order of packing/unpacking of bytes/words. • Support for pre-fetch for faster reads • Error capture and reporting for protocol errors, bus errors, and over/underflow UART Ports Serial Peripheral Interface (SPI) Ports The processor provides two full-duplex universal asynchronous receiver/transmitter (UART) ports, which are fully compatible with PC-standard 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, and none, even, or odd parity. Optionally, an additional address bit can be transferred to interrupt only addressed nodes in multi-drop bus (MDB) systems. A frame is terminated by a configurable number of stop bits. The processors have three industry-standard SPI-compatible ports that allow it to communicate with multiple SPI-compatible devices. The UART ports support automatic hardware flow control through the clear to send (CTS) input and request to send (RTS) output with programmable assertion FIFO levels. The baseline SPI peripheral is a synchronous, four-wire interface consisting of two data pins, one device select pin, and a gated clock pin. The two data pins allow full-duplex operation to other SPI-compatible devices. An additional two (optional) data pins are provided to support quad SPI operation. Enhanced modes of operation such as flow control, fast mode, and dual I/O mode (DIOM) are also supported. In addition, a direct memory access (DMA) mode allows for transferring several words with minimal CPU interaction. To help support the local interconnect network (LIN) protocols, a special command causes the transmitter to queue a break command of programmable bit length into the transmit buffer. Similarly, the number of stop bits can be extended by a programmable inter-frame space. With a range of configurable options, the SPI ports provide a glueless hardware interface with other SPI-compatible devices in master mode, slave mode, and multimaster environments. The SPI peripheral includes programmable baud rates, clock phase, and clock polarity. The peripheral can operate in a multimaster environment by interfacing with several other devices, acting as either a master device or a slave device. In a multimaster environment, the SPI peripheral uses open-drain outputs to avoid data bus contention. The flow control features enable slow slave devices to interface with fast master devices by providing an SPI Ready pin which flexibly controls the transfers. 2-Wire Controller Interface (TWI) The SPI port’s baud rate and clock phase/polarities are programmable, and it has integrated DMA channels for both transmit and receive data streams. Additionally, the TWI module is fully compatible with serial camera control bus (SCCB) functionality for easier control of various CMOS camera sensor devices. • RGB888 can be converted to RGB666 or RGB565 for transmit modes. • Various de-interleaving/interleaving modes for receiving/transmitting 4:2:2 YCrCb data. • Configurable LCD data enable (DEN) output available on Frame Sync 3. The capabilities of the UARTs are further extended with support for the Infrared Data Association (IrDA®) serial infrared physical layer link specification (SIR) protocol. The processor includes a 2-wire interface (TWI) module for providing a simple exchange method of control data between multiple devices. The TWI module is compatible with the widely used I2C bus standard. The TWI module offers the capabilities of simultaneous master and slave operation and support for both 7-bit addressing and multimedia data arbitration. The TWI interface utilizes two pins for transferring clock (TWI_SCL) and data (TWI_SDA) and supports the protocol at speeds up to 400k bits/sec. The TWI interface pins are compatible with 5 V logic levels. SPI Host Port (SPIHP) The processor includes one SPI host port which may be used in conjunction with any available SPI port to enhance its SPI slave mode capabilities. The SPIHP allows a SPI host device access to Rev.

The following list describes the main features of the MSI controller: The USB clock is provided through a dedicated external crystal or crystal oscillator. The USB OTG dual-role device controller includes a phase locked loop with programmable multipliers to generate the necessary internal clocking frequency for USB. • Support for a single MMC, SD memory, and SDIO card Housekeeping ADC (HADC) • Support for 1-bit and 4-bit SD modes The HADC provides a general-purpose, multichannel successive approximation analog-to-digital converter. It supports the following features: • Support for 1-bit, 4-bit, and 8-bit MMC modes • Support for eMMC 4.5 embedded NAND flash devices • Support for power management and clock control • An eleven-signal external interface with clock, command, optional interrupt, and up to eight data lines • Card interface clock generation from SCLK0 or SCLK1 • SDIO interrupt and read wait features • 12-bit ADC core with built-in sample and hold • 4 single-ended input channels • Throughput rates up to 1 MSPS • Single external reference with analog inputs between 0 V and 3.3 V • Selectable ADC clock frequency including the ability to program a prescaler Controller Area Network (CAN) A CAN controller implements 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 well suited for control applications due to its capability to communicate reliably over a network. This is because the protocol incorporates CRC checking, message error tracking, and fault node confinement. The CAN controller offers the following features: • 32 mailboxes (8 receive only, 8 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 • Adaptable conversion type: allows single or continuous conversion with option of autoscan • Auto sequencing capability with up to 4 autoconversions in a single session. Each conversion can be programmed to select any input channel. • Four data registers (individually addressable) to store conversion values System Crossbars (SCB) The system crossbars (SCB) are the fundamental building blocks of a switch-fabric style for (on-chip) system bus interconnection. The SCBs connect system bus masters to system bus slaves, providing concurrent data transfer between multiple bus masters and multiple bus slaves. A hierarchical model— built from multiple SCBs—provides a power and area efficient system interconnect, which satisfies the performance and flexibility requirements of a specific system. The SCBs provide the following features: • CAN wake-up from hibernation mode (lowest static power consumption mode) • Interrupts, including: TX complete, RX complete, error and global An additional crystal is not required to supply the CAN clock, as the CAN clock is derived from a system clock through a programmable divider. USB 2.0 On-the-Go Dual-Role Device Controller The USB 2.0 on-the-go (OTG) dual-role device controller provides a low-cost connectivity solution for the growing adoption of this bus standard in industrial applications, as well as consumer mobile devices such as cell phones, digital still cameras, and MP3 players. The USB 2.0 controller allows these devices to transfer data using a point-to-point USB connection without the need for a PC host. The module can operate in a traditional USB peripheral-only mode as well as the host mode presented in the OTG supplement to the USB 2.0 specification. • Highly efficient, pipelined bus transfer protocol for sustained throughput • Full-duplex bus operation for flexibility and reduced latency • Concurrent bus transfer support to allow multiple bus masters to access bus slaves simultaneously • Protection model (privileged/secure) support for selective bus interconnect protection POWER AND CLOCK MANAGEMENT The processor provides three operating modes, each with a different performance/power profile. Control of clocking to each of the processor peripherals also reduces power consumption. See Table 5 for a summary of the power settings for each mode. Rev.

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 SYS_CLKIN pin of the processor. When an external clock is used, the SYS_XTAL pin must be left unconnected. Alternatively, because the processor includes an on-chip oscillator circuit, an external crystal may be used. 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. Connect RTC pins RTC_CLKIN and RTC_XTAL with external components as shown in Figure 5. For fundamental frequency operation, use the circuit shown in Figure 4. A parallel-resonant, fundamental frequency, microprocessor grade crystal is connected across the SYS_CLKIN and SYS_XTAL pins. The on-chip resistance between SYS_CLKIN and the SYS_XTAL pin is in the 500 kΩ range. Further parallel resistors are typically not recommended. 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. RTC_CLKIN 0ȍ The two capacitors and the series resistor shown in Figure 4 fine-tune phase and amplitude of the sine frequency. The capacitor and resistor values shown in Figure 4 are typical values only. The capacitor values are dependent upon the load capacitance recommendations of the crystal manufacturer 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 on multiple devices over the required temperature range.

External Components for RTC 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 the alarm interrupt is 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 specific day and time of that day. TO PLL CIRCUITRY SYS_CLKIN RTC_XTAL R1 FOR OVERTONE OPERATION ONLY: 18 pF* The stopwatch function counts down from a programmed value, with one-second resolution. When the stopwatch interrupt is enabled and the counter underflows, an interrupt is generated. Clock Generation NOTE: VALUES MARKED WITH * MUST BE CUSTOMIZED, DEPENDING ON THE CRYSTAL AND LAYOUT. ANALYZE CAREFULLY. FOR FREQUENCIES ABOVE 33 MHz, THE SUGGESTED CAPACITOR VALUE OF 18pF SHOULD BE TREATED AS A MAXIMUM. Figure 4. External Crystal Connection 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 4. A design procedure for third-overtone operation is discussed in detail in application note (EE-168) Using Third Overtone Crystals with the ADSP-218x DSP (www.analog.com/ee-168). The clock generation unit (CGU) generates all on-chip clocks and synchronization signals. Multiplication factors are programmed to define the PLLCLK frequency. Programmable values divide the PLLCLK frequency to generate the core clock (CCLK), the system clocks (SYSCLK, SCLK0, and SCLK1), the LPDDR or DDR2 clock (DCLK), and the output clock (OCLK). Writing to the CGU control registers does not affect the behavior of the PLL immediately. Registers are first programmed with a new value, and the PLL logic executes the changes so that it transitions smoothly from the current conditions to the new ones. The same recommendations may be used for the USB crystal oscillator. Rev. D | Page 13 of 114 | February 2019 ADSP-BF700/701/702/703/704/705/706/707 SYS_CLKIN oscillations start when power is applied to the VDD_EXT pins. The rising edge of SYS_HWRST can be applied after all voltage supplies are within specifications, and SYS_CLKIN oscillations are stable. Clock Out/External Clock The SYS_CLKOUT output pin has programmable options to output divided-down versions of the on-chip clocks. By default, the SYS_CLKOUT pin drives a buffered version of the SYS_ CLKIN input. Clock generation faults (for example, PLL unlock) may trigger a reset by hardware. The clocks shown in Table 3 can be output on the SYS_CLKOUT pin. Table 3.

There are no sequencing requirements for the various power domains, but all domains must be powered according to the appropriate Specifications table for processor operating conditions; even if the feature/peripheral is not used. Table 4. Power Domains Power Domain All Internal Logic DDR2/LPDDR USB OTP Memory HADC RTC All Other I/O (Includes SYS, JTAG, and Ports Pins) VDD Range VDD_INT VDD_DMC VDD_USB VDD_OTP VDD_HADC VDD_RTC VDD_EXT The dynamic power management feature of the processor allows the processor’s core 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% reduction in dynamic power dissipation. 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. Deep Sleep Operating Mode—Maximum Dynamic Power Savings The deep sleep mode maximizes dynamic power savings by disabling the clocks to the processor core and to all synchronous peripherals. Asynchronous peripherals may still be running but cannot access internal resources or external memory. Table 5. Power Settings fSYSCLK, fDCLK, PLL fSCLK0, fSCLK1 Mode/State PLL Bypassed fCCLK Full On Enabled No Enabled Enabled Deep Sleep Disabled — Disabled Disabled Hibernate Disabled — Disabled Disabled Core Power On On Off Hibernate State—Maximum Static Power Savings The hibernate state maximizes static power savings by disabling the voltage and clocks to the processor core and to all of the peripherals. This setting signals the external voltage regulator supplying the VDD_INT pins to shut off using the SYS_ EXTWAKE signal, which provides the lowest static power dissipation. Any critical information stored internally (for example, memory contents, register contents, and other information) must be written to a nonvolatile storage device (or self-refreshed DRAM) prior to removing power if the processor state is to be preserved. Because the VDD_EXT pins can still be 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. Reset Control Unit Reset is the initial state of the whole processor or the core and is the result of a hardware- or software-triggered event. In this state, all control registers are set to their default values and functional units are idle. Exiting a full system reset starts with the core being ready to boot. The reset control unit (RCU) controls how all the functional units enter and exit reset. Differences in functional requirements and clocking constraints define how reset signals are generated. Programs must guarantee that none of the reset functions puts the system into an undefined state or causes resources to stall. This is particularly important when the core is reset (programs must ensure that there is no pending system activity involving the core when it is being reset). See Table 5 for a summary of the power settings for each mode. Rev. D | Page 14 of 114 | February 2019 ADSP-BF700/701/702/703/704/705/706/707 From a system perspective, reset is defined by both the reset target and the reset source described as follows in the following list. Target defined: • Hardware Reset—All functional units are set to their default states without exception. History is lost. • System Reset—All functional units except the RCU are set to their default states. • Core-only Reset—Affects the core only. The system software should guarantee that the core, while in reset state, is not accessed by any bus master. Source defined: • Hardware Reset—The SYS_HWRST input signal is asserted active (pulled down). • System Reset—May be triggered by software (writing to the RCU_CTL register) or by another functional unit such as the dynamic power management (DPM) unit (hibernate) or any of the system event controller (SEC), trigger routing unit (TRU), or emulator inputs. • Core-only Reset—Triggered by software. • Trigger request (peripheral). Voltage Regulation The processor requires an external voltage regulator to power the VDD_INT pins. To reduce standby power consumption, the external voltage regulator can be signaled through  SYS_EXTWAKE to remove power from the processor core. This signal is high-true for power-up and may be connected directly to the low-true shut-down input of many common regulators. While in the hibernate state, all external supply pins (VDD_ EXT, VDD_USB, and VDD_DMC) can still be powered, eliminating the need for external buffers. The external voltage regulator can be activated from this power down state by asserting the SYS_HWRST pin, which then initiates a boot sequence. SYS_EXTWAKE indicates a wake-up to the external voltage regulator. SYSTEM DEBUG The processor includes various features that allow for easy system debug. These are described in the following sections. System Watchpoint Unit The system watchpoint unit (SWU) is a single module which connects to a single system bus and provides for transaction monitoring. One SWU is attached to the bus going to each system slave. The SWU provides ports for all system bus address channel signals. Each SWU contains four match groups of registers with associated hardware. These four SWU match groups operate independently, but share common event (interrupt, trigger, and others) outputs. Rev. D | Page 15 of 114 Debug Access Port The debug access port (DAP) provides IEEE-1149.1 JTAG interface support through its JTAG debug and serial wire debug port (SWJ-DP). SWJ-DP is a combined JTAG-DP and SW-DP that enables either serial wire debug (SWD) or a JTAG emulator to be connected to a target. SWD signals share the same pins as JTAG. The DAP provides an optional instrumentation trace for both the core and system. It provides a trace stream that conforms to MIPI System Trace Protocol version 2 (STPv2). DEVELOPMENT TOOLS Analog Devices supports its processors with a complete line of software and hardware development tools, including integrated development environments (CrossCore® Embedded Studio), evaluation products, emulators, and a wide variety of software add-ins. Integrated Development Environments (IDEs) CrossCore Embedded Studio is based on the EclipseTM framework. Supporting most Analog Devices processor families, it is the IDE of choice for future processors, including multicore devices. CrossCore Embedded Studio seamlessly integrates available software add-ins to support real time operating systems, file systems, TCP/IP stacks, USB stacks, algorithmic software modules, and evaluation hardware board support packages.

It also supports in-circuit programming of the on-board Flash device to store user-specific boot code, enabling standalone operation. With the full version of CrossCore Embedded Studio installed (sold separately), engineers can develop software for supported EZ-KITs or any custom system utilizing supported Analog Devices processors. | February 2019 ADSP-BF700/701/702/703/704/705/706/707 ADSP-BF706 EZ-KIT Mini Designing an Emulator-Compatible DSP Board (Target) TM The ADSP-BF706 EZ-KIT Mini product (ADZS-BF706EZMini) contains the ADSP-BF706 processor and is shipped with all of the necessary hardware. Users can start their evaluation immediately. The EZ-KIT Mini product includes the standalone evaluation board and USB cable. The EZ-KIT Mini ships with an on-board debug agent. The evaluation board is designed to be used in conjunction with the CrossCore Embedded Studio (CCES) development tools to test capabilities of the ADSP-BF706 Blackfin processor. Blackfin Low Power Imaging Platform (BLIP) The Blackfin low power imaging platform (BLIP) integrates the ADSP-BF707 Blackfin processor and Analog Devices software code libraries. The code libraries are optimized to detect the presence and behavior of humans or vehicles in indoor and outdoor environments. The BLIP hardware platform is delivered preloaded with the occupancy software module. Software Add-Ins for CrossCore Embedded Studio Analog Devices offers software add-ins which seamlessly integrate with CrossCore Embedded Studio to extend its capabilities and reduce development time. Add-ins include board support packages for evaluation hardware, various middleware packages, and algorithmic modules. Documentation, help, configuration dialogs, and coding examples present in these add-ins are viewable through the CrossCore Embedded Studio IDE once the add-in is installed. For embedded system test and debug, Analog Devices provides a family of emulators. On each DAP-enabled processor, Analog Devices supplies an IEEE 1149.1 JTAG test access port (TAP), serial wire debug port (SWJ-DP), and trace capabilities.  In-circuit emulation is facilitated by use of the JTAG or SWD interface. The emulator accesses the processor’s internal features through the processor’s TAP, allowing the developer to load code, set breakpoints, and view variables, memory, and registers. The emulators require the target board to include a header(s) that supports connection of the processor’s DAP to the emulator for trace and debug. Analog Devices emulators actively drive JTG_TRST high. Third-party emulators may expect a pull-up on JTG_TRST and therefore will not drive JTG_TRST high. When using this type of third-party emulator JTG_TRST must still be driven low during power-up reset, but should subsequently be driven high externally before any emulation or boundary-scan operations. See Power-Up Reset Timing for more information on POR specifications. For more details on target board design issues including mechanical layout, single processor connections, signal buffering, signal termination, and emulator pod logic, contact the factory for more information.

The columns in this table provide the following information: • Power Domain: The Power Domain column in the table specifies the power supply domain in which the signal resides. • Signal Name: The Signal Name column in the table includes the signal name for every pin and (where applicable) the GPIO multiplexed pin function for every pin. • Description and Notes: The Description and Notes column in the table identifies any special requirements or characteristics for the signal. If no special requirements are listed the signal may be left unconnected if it is not used. Also, for multiplexed general-purpose I/O pins, this column identifies the functions available on the pin. • Pin Type: The Type column in the table identifies the I/O type or supply type of the pin. The abbreviations used in this column are na (none), I/O (input/output), a (analog), s (supply), and g (ground). If an external pull-up or pull-down resistor is required for any signal, 100 kΩ is the maximum value that can be used unless otherwise noted. • Driver Type: The Driver Type column in the table identifies the driver type used by the pin. The driver types are defined in the output drive currents section of this data sheet. Note that for Port A, Port B, and Port C (PA_00 to PC_14), when SYS_HWRST is low, these pads are three-state. After  SYS_HWRST is released, but before code execution begins, these pins are internally pulled up. Subsequently, the state depends on the input enable and output enable which are controlled by software. • Internal Termination: The Int Term column in the table specifies the termination present when the processor is not in the reset or hibernate state. The abbreviations used in this column are wk (weak keeper, weakly retains previous value driven on the pin), pu (pull-up), or pd (pull-down). Software control of internal pull-ups works according to the following settings in the PADS_PCFG0 register. When  PADS_PCFG0 = 0: For PA_15:PA_00, PB_15:PB_00, and  PC_14:PC_00, the internal pull-up is enabled when both the input enable and output enable of a particular pin are  deasserted. When PADS_PCFG0 = 1: For PA_15:PA_00,  PB_15:PB_00, and PC_14:PC_00, the internal pull-up is enabled as long as the output enable of a particular pin is  deasserted. • Reset Termination: The Reset Term column in the table specifies the termination present when the processor is in the reset state. The abbreviations used in this column are wk (weak keeper, weakly retains previous value driven on the pin), pu (pull-up), or pd (pull-down). • Reset Drive: The Reset Drive column in the table specifies the active drive on the signal when the processor is in the reset state. There are some exceptions to this scheme: • Hibernate Termination: The Hiber Term column in the table specifies the termination present when the processor is in the hibernate state. The abbreviations used in this column are wk (weak keeper, weakly retains previous value driven on the pin), pu (pull-up), or pd (pull-down). • Internal pull-ups are always disabled if MSI mode is selected for that signal. • The following signals enabled the internal pull-down when the output enable is de-asserted: SMC0_AMS[1:0],  SMC0_ARE, SMC0_AWE, SMC0_AOE, SMC0_ARDY, SPI0_SEL[6:1], SPI1_SEL[4:1], and SPI2_SEL[3:1]. • Hibernate Drive: The Hiber Drive column in the table specifies the active drive on the signal when the processor is in the hibernate state.

Due to the dependency on these factors the measured jitter may be higher or lower than this typical specification for each end application. 2 The value in the Typ field is the percentage of the SYS_CLKOUT period. 3 The maximum achievable frequency for any peripheral in external clock mode is dependent on being able to meet the setup and hold times in the ac timing specifications section for that peripheral. Pay particular attention to setup and hold times for VDD_EXT = 1.8 V which may preclude the maximum frequency listed here. 4 The peripheral external clock frequency must also be less than or equal to the fSCLK that clocks the peripheral.

The power dissipated by each clock domain is dependent on voltage (VDD_INT), operating frequency and a unique scaling factor. 1. Static, including leakage current (deep sleep) 2. Dynamic, due to transistor switching characteristics for each clock domain Many operating conditions can also affect power dissipation, including temperature, voltage, operating frequency, and processor activity. The following equation describes the internal current consumption. IDDINT_TOT = IDDINT_DEEPSLEEP + IDDINT_CCLK_DYN + IDDINT_PLLCLK_DYN + IDDINT_SYSCLK_DYN +  IDDINT_SCLK0_DYN + IDDINT_SCLK1_DYN +  IDDINT_DCLK_DYN + IDDINT_DMA_DR_DYN +  IDDINT_USBCLK_DYN IDDINT_PLLCLK_DYN (mA) = 0.012 × fPLLCLK (MHz) × VDD_INT (V) IDDINT_SYSCLK_DYN (mA) = 0.120 × fSYSCLK (MHz) × VDD_INT (V) IDDINT_SCLK0_DYN (mA) = 0.110 × fSCLK0 (MHz) × VDD_INT (V) IDDINT_SCLK1_DYN (mA) = 0.068 × fSCLK1 (MHz) × VDD_INT (V) IDDINT_DCLK_DYN (mA) = 0.055 × fDCLK (MHz) × VDD_INT (V) The dynamic component of the USB clock is a unique case. The USB clock contributes a near constant current value when used. IDDINT_DEEPSLEEP is the only item present that is part of the static power dissipation component. IDDINT_DEEPSLEEP is specified as a function of voltage (VDD_INT) and temperature (see Table 21). There are eight different items that contribute to the dynamic power dissipation. These components fall into three broad categories: application-dependent currents, clock currents, and data transmission currents. Table 20. IDDINT_USBCLK_DYN Current Is USB Enabled? IDDINT_USBCLK_DYN (mA) Yes – High-Speed Mode 13.94 Yes – Full-Speed Mode 10.83 Yes – Suspend Mode 5.2 No 0.34 Application-Dependent Current Data Transmission Current The application-dependent currents include the dynamic current in the core clock domain. The data transmission current represents the power dissipated when transmitting data. This current is expressed in terms of data rate. The calculation is performed by adding the data rate (MB/s) of each DMA-driven access to peripherals, L1, L2, and external memory. This number is then multiplied by a weighted data-rate coefficient and VDD_INT: Core clock (CCLK) use is subject to an activity scaling factor (ASF) that represents application code running on the processor cores and L1/L2 memories (Table 22). The ASF is combined with the CCLK frequency and VDD_INT dependent data in Table 23 to calculate this portion. IDDINT_CCLK_DYN (mA) = Table 23 × ASF IDDINT_DMADR_DYN (mA) = Weighted DRC × Total Data Rate (MB/s) × VDD_INT (V) A weighted data-rate coefficient is used because different coefficients exist depending on the source and destination of the transfer. For details on using this equation and calculating the weighted DRC, see the related Engineer Zone material. For a quick maximum calculation, the weighted DRC can be assumed to be 0.0497, which is the coefficient for L1 to L1 transfers. Rev.

A power-up reset is initiated by asserting  SYS_HWRST and JTG_TRST. During power-up reset, all pins are high impedance except for those noted in the ADSP-BF70x Designer Quick Reference. Both JTG_TRST and SYS_HWRST need to be asserted upon power-up, but only SYS_HWRST needs to be released for the device to boot properly. JTG_TRST may be asserted indefinitely for normal operation. JTG_TRST only needs to be released when using an emulator to connect to the DAP for debug or boundary scan. There is an internal pull-down on JTG_TRST to ensure internal emulation logic will always be properly initialized during power-up reset. Table 29 and Figure 8 show the relationship between power supply startup and processor reset timing, related to the clock generation unit (CGU) and reset control unit (RCU). In Figure 8, VDD_SUPPLIES are VDD_INT, VDD_EXT, VDD_DMC, VDD_USB, VDD_RTC, VDD_OTP, and VDD_HADC. There is no power supply sequencing requirement for the ADSP-BF70x processor. However, if saving power during power-on is important, bringing up VDD_INT last is recommended. This avoids a small current drain in the VDD_INT domain during the transition period of I/O voltages from 0 V to within the voltage specification. Table 29.

Driver Type B and Device Driver C (DDR Drive Strength 60 Ω) TEST CONDITIONS All timing parameters appearing in this data sheet were measured under the conditions described in this section. Figure 61 shows the measurement point for ac measurements (except output enable/disable). The measurement point, VMEAS, is VDD_EXT/2 for VDD_EXT (nominal) = 1.8 V/3.3 V. Capacitive Loading Output delays and holds are based on standard capacitive loads of an average of 6 pF on all pins (see Figure 63). VLOAD is equal to VDD_EXT/2.

Voltage Reference Levels for AC Measurements (Except Output Enable/Disable) 0.5pF 2pF 400: Output Enable Time Measurement Output pins are considered enabled when they make 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 62. If multiple pins are enabled, the measurement value is that of the first pin to start driving. NOTES: THE WORST CASE TRANSMISSION LINE DELAY IS SHOWN AND CAN BE USED FOR THE OUTPUT TIMING ANALYSIS TO REFLECT THE TRANSMISSION LINE EFFECT AND MUST BE CONSIDERED. THE TRANSMISSION LINE (TD) IS FOR LOAD ONLY AND DOES NOT AFFECT THE DATA SHEET TIMING SPECIFICATIONS. ANALOG DEVICES RECOMMENDS USING THE IBIS MODEL TIMING FOR A GIVEN SYSTEM REQUIREMENT. IF NECESSARY, A SYSTEM MAY INCORPORATE EXTERNAL DRIVERS TO COMPENSATE FOR ANY TIMING DIFFERENCES. Figure 63. Equivalent Device Loading for AC Measurements (Includes All Fixtures) Output Disable Time Measurement Output pins are considered disabled when they stop driving, enter a high impedance state, and start to decay from the output high or low voltage. The output disable time, tDIS, is the interval from when a reference signal reaches a high or low voltage level to the point when the output stops driving, as shown on the left side of Figure 62.
