Every instruction can execute in a single cycle. Fabrication in CMOS results in low power dissipation. The ADSP-2100 Family's flexible architecture and comprehensive instruction set support a high degree of parallelism. In one cycle the ADSP-216x can perform all of the following operations: GENERAL DESCRIPTION The ADSP-216x Family processors are single-chip microcomputers optimized for digital signal processing (DSP) and other high speed numeric processing applications. The ADSP-216x processors are all built upon a common core with ADSP-2100. Each processor combines the core DSP architecture--computation units, data address generators and program sequencer--with features such as on-chip program ROM and data memory RAM, a programmable timer and two serial ports. The ADSP-2165/ADSP-2166 also adds program memory and power-down mode. This data sheet describes the following ADSP-216x Family processors: ADSP-2161/ADSP-2162/ ADSP-2163/ADSP-2164 ADSP-2165/ADSP-2166 Custom ROM-programmed DSPs: ROM-programmed ADSP-216x processors with power-down and larger on-chip memories (12K Program Memory ROM, 1K Program Memory RAM, 4K Data Memory RAM) * Generate the next program address * Fetch the next instruction * Perform one or two data moves * Update one or two data address pointers * Perform a computation * Receive and transmit data via one or two serial ports Table I shows the features of each ADSP-216x processor. The ADSP-216x series are memory-variant versions of the ADSP-2101 and ADSP-2103 that contain factory-programmed on-chip ROM program memory. These devices offer different amounts of on-chip memory for program and data storage. Table I shows the features available in the ADSP-216x series of custom ROM-coded processors. The ADSP-216x products eliminate the need for an external boot EPROM in your system, and can also eliminate the need for any external program memory by fitting the entire application program in on-chip ROM. These devices thus provide an excellent option for volume applications where board space and system cost constraints are of critical concern.

The ADSP-2100 Family Development Software includes C and assembly language tools that allow programmers to write code for any of the ADSP-216x processors. The ANSI C compiler generates ADSP-216x assembly source code, while the runtime C library provides ANSIstandard and custom DSP library routines. The ADSP-216x assembler produces object code modules that the linker combines into an executable file. The processor simulators provide an interactive instruction-level simulation with a reconfigurable, windowed user interface. A PROM splitter utility generates PROM programmer compatible files. EZ-ICE(R) in-circuit emulators allow debugging of ADSP-21xx systems by providing a full range of emulation functions such as modification of memory and register values and execution breakpoints. EZ-LAB(R) demonstration boards are complete DSP systems that execute EPROM-based programs. The EZ-Kit Lite is a very low-cost evaluation/development platform that contains both the hardware and software needed to evaluate the ADSP-21xx architecture. Additional details and ordering information are available in the ADSP-2100 Family Software & Hardware Development Tools data sheet (ADDS-21xx-TOOLS). This data sheet can be requested from any Analog Devices sales office or distributor. Additional Information Figure 1 shows a block diagram of the ADSP-216x architecture. The processors contain three independent computational units: the ALU, the multiplier/accumulator (MAC), and the shifter. The computational units process 16-bit data directly and have provisions to support multiprecision computations. The ALU performs a standard set of arithmetic and logic operations; division primitives are also supported. The MAC performs single-cycle multiply, multiply/add, and multiply/subtract operations. The shifter performs logical and arithmetic shifts, normalization, denormalization, and derive exponent operations. The shifter can be used to efficiently implement numeric format control including multiword floating-point representations. The internal result (R) bus directly connects the computational units so that the output of any unit may be used as the input of any unit on the next cycle. A powerful program sequencer and two dedicated data address generators ensure efficient use of these computational units. The sequencer supports conditional jumps, subroutine calls, and returns in a single cycle. With internal loop counters and loop stacks, the ADSP-216x executes looped code with zero overhead--no explicit jump instructions are required to maintain the loop. Two data address generators (DAGs) provide addresses for simultaneous dual operand fetches (from data memory and program memory). Each DAG maintains and updates four address pointers. Whenever the pointer is used to access data (indirect addressing), it is post-modified by the value of one of four modify registers. A length value may be associated with each pointer to implement automatic modulo addressing for circular buffers. The circular buffering feature is also used by the serial ports for automatic data transfers to (and from) onchip memory. This data sheet provides a general overview of ADSP-216x processor functionality.

ADSP-216x Block Diagram Efficient data transfer is achieved with the use of five internal buses: * * * * * Program Memory Address (PMA) Bus Program Memory Data (PMD) Bus Data Memory Address (DMA) Bus Data Memory Data (DMD) Bus Result (R) Bus external boot memory. Multiple programs can be selected and loaded from the EPROM with no additional hardware. The data receive and transmit pins on SPORT1 (Serial Port 1) can be alternatively configured as a general-purpose input flag and output flag. You can use these pins for event signalling to and from an external device. A programmable interval timer can generate periodic interrupts. A 16-bit count register (TCOUNT) is decremented every n cycles, where n-1 is a scaling value stored in an 8-bit register (TSCALE). When the value of the count register reaches zero, an interrupt is generated and the count register is reloaded from a 16-bit period register (TPERIOD). Serial Ports The two address buses (PMA, DMA) share a single external address bus, allowing memory to be expanded off-chip, and the two data buses (PMD, DMD) share a single external data bus. The BMS, DMS and PMS signals indicate which memory space is using the external buses. Program memory can store both instructions and data, permitting the ADSP-216x to fetch two operands in a single cycle, one from program memory and one from data memory. The processor can fetch an operand from on-chip program memory and the next instruction in the same cycle. The memory interface supports slow memories and memorymapped peripherals with programmable wait state generation. External devices can gain control of the processor's buses with the use of the bus request/grant signals (BR, BG). One bus grant execution mode (GO Mode) allows the ADSP216x to continue running from internal memory. A second execution mode requires the processor to halt while buses are granted. Each ADSP-216x processor can respond to several different interrupts. There can be up to three external interrupts, configured as edge- or level-sensitive. Internal interrupts can be generated by the timer and serial ports. There is also a master RESET signal. Booting circuitry provides for loading on-chip program memory automatically from byte-wide external memory. After reset, three wait states are automatically generated. This allows, for example, a 60 ns ADSP-2161 to use a 200 ns EPROM as The ADSP-216x processors include two synchronous serial ports (SPORTs) for serial communications and multiprocessor communication. All of the ADSP-216x processors have two serial ports (SPORT0, SPORT1). The serial ports provide a complete synchronous serial interface with optional companding in hardware. A wide variety of framed or frameless data transmit and receive modes of operation are available. Each SPORT can generate an internal programmable serial clock or accept an external serial clock. Each serial port has a 5-pin interface consisting of the following signals: Signal Name SCLK RFS TFS DR DT Function Serial Clock (I/O) Receive Frame Synchronization (I/O) Transmit Frame Synchronization (I/O) Serial Data Receive Serial Data Transmit -4- REV. 0 ADSP-216x The ADSP-216x serial ports offer the following capabilities: Bidirectional--Each SPORT has a separate, double-buffered transmit and receive function. Flexible Clocking--Each SPORT can use an external serial clock or generate its own clock internally. Flexible Framing--The SPORTs have independent framing for the transmit and receive functions; each function can run in a frameless mode or with frame synchronization signals internally generated or externally generated; frame sync signals may be active high or inverted, with either of two pulsewidths and timings. Different Word Lengths--Each SPORT supports serial data word lengths from 3 to 16 bits. Companding in Hardware--Each SPORT provides optional A-law and -law companding according to CCITT recommendation G.711. Flexible Interrupt Scheme--Receive and transmit functions can generate a unique interrupt upon completion of a data word transfer. Autobuffering with Single-Cycle Overhead--Each SPORT can automatically receive or transmit the contents of an entire circular data buffer with only one overhead cycle per data word; an interrupt is generated after the transfer of the entire buffer is completed. Multichannel Capability (SPORT0 Only)--SPORT0 provides a multichannel interface to selectively receive or transmit a 24-word or 32-word, time-division multiplexed serial bit stream; this feature is especially useful for T1 or CEPT interfaces, or as a network communication scheme for multiple processors. Alternate Configuration--SPORT1 can be alternatively configured as two external interrupt inputs (IRQ0, IRQ1) and the Flag In and Flag Out signals (FI, FO). Interrupts The ADSP-216x uses a vectored interrupt scheme: when an interrupt is acknowledged, the processor shifts program control to the interrupt vector address corresponding to the interrupt received. Interrupts can be optionally nested so that a higher priority interrupt can preempt the currently executing interrupt service routine. Each interrupt vector location is four instructions in length so that simple service routines can be coded entirely in this space. Longer service routines require an additional JUMP or CALL instruction. Individual interrupt requests are logically ANDed with the bits in the IMASK register; the highest-priority unmasked interrupt is then selected. The interrupt control register, ICNTL, allows the external interrupts to be set as either edge- or level-sensitive. Depending on Bit 4 in ICNTL, interrupt service routines can either be nested (with higher priority interrupts taking precedence) or be processed sequentially (with only one interrupt service active at a time). The interrupt force and clear register, IFC, is a write-only register that contains a force bit and a clear bit for each interrupt. When responding to an interrupt, the ASTAT, MSTAT and IMASK status registers are pushed onto the status stack and the PC counter is loaded with the appropriate vector address. The status stack is seven levels deep to allow interrupt nesting. The stack is automatically popped when a return from the interrupt instruction is executed. Pin Definitions Pin Function Descriptions show pin definitions for the ADSP216x processors. Any inputs not used must be tied to VDD. SYSTEM INTERFACE Figure 3 shows a typical system for the ADSP-216x with two serial I/O devices, an optional external program and data memory. A total of 12K words of data memory and 15K words of program memory is addressable. Programmable wait-state generation allows the processors to easily interface to slow external memories. The ADSP-216x processors also provide either: one external interrupt (IRQ2) and two serial ports (SPORT0, SPORT1), or three external interrupts (IRQ2, IRQ1, IRQ0) and one serial port (SPORT0). Clock Signals The ADSP-216x's interrupt controller lets the processor respond to interrupts with a minimum of overhead. Up to three external interrupt input pins, IRQ0, IRQ1 and IRQ2, are provided. IRQ2 is always available as a dedicated pin; IRQ1 and IRQ0 may be alternately configured as part of Serial Port 1. The ADSP-216x also supports internal interrupts from the timer and the serial ports. The interrupts are internally prioritized and individually maskable (except for RESET which is nonmaskable). The IRQx input pins can be programmed for either level- or edge-sensitivity. The interrupt priorities for each ADSP-216x processor are shown in Table II. Table II. Interrupt Vector Addresses and Priority The ADSP-216x processors' CLKIN input may be driven by a crystal or by a TTL-compatible external clock signal. The CLKIN input may not be halted or changed in frequency during operation, nor operated below the specified low frequency limit. If an external clock is used, it should be a TTL-compatible signal running at the instruction rate. The signal should be connected to the processor's CLKIN input; in this case, the XTAL input must be left unconnected. Because the ADSP-216x processors include an on-chip oscillator circuit, an external crystal may also be used. The crystal should be connected across the CLKIN and XTAL pins, with two capacitors connected as shown in Figure 2. A parallelresonant, fundamental frequency, microprocessor-grade crystal should be used. ADSP-216x Interrupt Source RESET Startup IRQ2 or Power-Down SPORT0 Transmit SPORT0 Receive SPORT1 Transmit or IRQ1 SPORT1 Receive or IRQ0 Timer Interrupt Vector Address 0x0000 0x0004 (High Priority) 0x0008 0x000C 0x0010 0x0014 0x0018 (Low Priority) REV. 0 -5- ADSP-216x CLKIN XTAL CLKOUT ADSP-216x Figure 2. External Crystal Connections A clock output signal (CLKOUT) is generated by the processor, synchronized to the processor's internal cycles. Reset The power-up sequence is defined as the total time required for the crystal oscillator circuit to stabilize after a valid VDD is applied to the processor and for the internal phase-locked loop (PLL) to lock onto the specific crystal frequency. A minimum of 2000 tCK cycles will ensure that the PLL has locked (this does not, however, include the crystal oscillator start-up time). During this power-up sequence the RESET signal should be held low. On any subsequent resets, the RESET signal must meet the minimum pulsewidth specification, tRSP. To generate the RESET signal, use either an RC circuit with an external Schmidt trigger or a commercially available reset IC. (Do not use only an RC circuit.) The RESET input resets all internal stack pointers to the empty stack condition, masks all interrupts, and clears the MSTAT register. When RESET is released, the boot loading sequence is performed (provided there is no pending bus request and the chip is configured for booting, with MMAP = 0). The first instruction is then fetched from internal program memory location 0x0000. The RESET signal initiates a complete reset of the ADSP-216x. The RESET signal must be asserted when the chip is powered up to assure proper initialization. If the RESET signal is applied during initial power-up, it must be held long enough to allow the processor's internal clock to stabilize. If RESET is activated at any time after power-up and the input clock frequency does not change, the processor's internal clock continues and does not require this stabilization time.

The external data bus is bidirectional and is 24 bits wide to allow instruction fetches from external program memory. Program memory may contain code and data. The external address bus is 14 bits wide. For the ADSP-216x, these lines can directly address up to 16K words, of which 2K are on-chip. The data lines are bidirectional. The program memory select (PMS) signal indicates accesses to program memory and can be used as a chip select signal. The write (WR) signal indicates a write operation and is used as a write strobe. The read (RD) signal indicates a read operation and is used as a read strobe or output enable signal. The ADSP-216x processors write data from their 16-bit registers to 24-bit program memory using the PX register to provide the lower eight bits. When the processor reads 16-bit data from 24-bit program memory to a 16-bit data register, the lower eight bits are placed in the PX register. The program memory interface can generate 0 to 7 wait states for external memory devices; default is to 7 wait states after RESET. Program Memory Maps MMAP = 0 MMAP = 1 Figure 4.

Control and status registers for the system, timer, wait-state configuration, and serial port operations are located in this region of memory. The remaining 8K of data memory is located off-chip. This external data memory is divided into three zones, each associated with its own wait-state generator. This allows slower peripherals to be memory-mapped into data memory for which wait states are specified. By mapping peripherals into different zones, you can accommodate peripherals with different waitstate requirements. All zones default to 7 wait states after RESET. Figure 8.

All zones default to seven wait states after RESET. -8- REV. 0 ADSP-216x Bus Interface The ADSP-216x processors can relinquish control of their data and address buses to an external device. When the external device requires control of the buses, it asserts the bus request signal (BR). If the ADSP-216x is not performing an external memory access, it responds to the active BR input in the next cycle by: * Three-stating the data and address buses and the PMS, DMS, BMS, RD, WR output drivers, * Asserting the bus grant (BG) signal, and halting program execution. If the Go mode is set, however, the ADSP-216x will not halt program execution until it encounters an instruction that requires an external memory access. If the ADSP-216x is performing an external memory access when the external device asserts the BR signal, it will not threestate the memory interfaces or assert the BG signal until the cycle after the access completes (up to eight cycles later depending on the number of wait states). The instruction does not need to be completed when the bus is granted; the ADSP-21xx will grant the bus between two memory accesses if an instruction requires more than one external memory access. When the BR signal is released, the processor releases the BG signal, re-enables the output drivers and continues program execution from the point at which it stopped. The bus request feature operates at all times, including when the processor is booting and when RESET is active. If this feature is not used, the BR input should be tied high (to VDD). POWER-DOWN * Low-to-high transition of the power-down flag input pin (PWDFLAG) can be used to terminate power-down. * The RESET pin also can also be used to terminate power-down. Power-Down Control Several parameters of power-down operation can be controlled through control bits of the "power-down/sportl autobuffer control register." This control register is memory-mapped at location 0x3FEF and the power-down control bits are as follows: bit[15] xtal: xtal pin disable during power-down 1 = disabled, 0 = enable (default) bit[14] pwdflag: (read only ) when pwdena = 1, the value of bit [14] pwdflag is equal to the status of the pwdflag input pin. when pwdena = 0, the value of bit [14] pwdflag is equal to 0. bit[13] pwdena: power-down enable 1 = enable, 0 = disable (default) if pwdena is set to 0, then the output pin PWDACK is driven low and the input pin PWDFLAG is disabled Note: It is not recommended that power-down enable be set or cleared during an IRQ2 interrupt. bit[12] pucr: power-up context reset 1 = soft reset, 0 = resume execution (default) Entering Power-Down The power-down sequence is defined as follows: * Enable power-down logic by setting the pwdena bit in the power-down/sportl autobuffer control register. Note: In order to power-down, the PWDENA bit must be set before the IRQ2 interrupt is initiated. * Initiate the power-down sequence by generating an IRQ2 interrupt either externally or by software use of the IFC register. * The processor vectors to the IRQ2 interrupt vector located at 0x0004. * Any number of housekeeping instructions, starting at location 0x0004 can be executed prior to the processor entering the power-down mode. * The processor enters the power-down mode when the processor executes an IDLE instruction while executing the IRQ2 interrupt routine. Notes: * If an RTI instruction is executed before the processor encounter an IDLE instruction, then the processor returns from the IRQ2 interrupt and the power-down sequence is aborted. * The user can differentiate between a "normal" IRQ2 interrupt and a "power-down" IRQ2 interrupt by resetting the PWDFLAG pin and checking the status of this pin by testing the PWDFLAG bit in the power-down/SPORT1 autobuffer control register located at DM[0x3FEF]. The ADSP-2165/ADSP-2166 processors have a low power feature that lets the processor enter a very low power dormant state through hardware or software control. A list of powerdown features follows: * Processor registers and on-chip memory contents are maintained during power-down. * Power-down mode holds the processor in CMOS standby with a maximum current of less than 100 A in some modes. * Support for an externally generated TTL or CMOS processor clock. The external clock can continue running during power-down without affecting the lowest power rating. * Support for crystal operation includes disabling the oscillator to save power. (The processor automatically waits 4096 CLKIN cycles for the crystal oscillator to start and stabilize). * When power-down mode is enabled, powering down of the processor can be initiated either by externally generated IRQ2 interrupt or by using the IRQ2 force bit in the IFC register. * Power-Down Acknowledge Pin (PWDACK) indicates when the processor has entered power-down. * Interrupt support allows an unlimited number of instructions to be executed before optionally powering down. * Context clear/save control allows the processor to continue where it left off or start with a clean context when leaving the power-down state. REV. 0 -9- ADSP-216x Exiting Power-Down ADSP-216x Prototyping The power-down mode can be exited with the use of the PWDFLAG or RESET pin. Applying a low-to-high transition to the PWDFLAG pin takes the processor out of power-down mode. In this case, a delay of 4096 cycles is automatically induced by the processor. Also, depending on the status of the power-up context reset bit (pucr), the processor either 1) continues to execute instructions following the IDLE instruction that caused the power-down. A RTI instruction is required to pass control back to the main routine (pucr = 0) or 2) resumes operation from power-down by clearing the PC, STATUS, LOOP and CNTR stack. The IMASK and ASTAT registers are set to 0 and the SSTAT goes to 0x55. The processor then starts executing instructions from the address zero (pucr = 1). In the case where the power-down mode is exited by asserting the RESET pin, the processor state is reset and instruction are executed from address 0x0000. The RESET pin in this case must be held low long enough for the external crystal (if any) and the on-chip PLL to stabilize and lock. Low Power IDLE Instruction You can prototype your ADSP-216x system with either ADSP2101 or ADSP-2103 RAM-based processors. When code is fully developed and debugged, it can be submitted to Analog Devices for conversion into an ADSP-216x ROM product. The ADSP-2101 EZ-ICE emulator can be used for development of ADSP-216x systems. For the 3.3 V ADSP-2162/ADSP-2164 and ADSP-2166, a voltage converter interface board provides 3.3 V emulation. Additional overlay memory is used for emulation of ADSP2161/ADSP-2162 systems. It should be noted that due to the use of off-chip overlay memory to emulate the ADSP-2161/ ADSP-2162, a performance loss may be experienced when both executing instructions and fetching program memory data from the off-chip overlay memory in the same cycle. This can be overcome by locating program memory data in on-chip memory. Ordering Procedure for ADSP-216x ROM Processors To place an order for a custom ROM-coded ADSP-2161, ADSP-2162, ADSP-2163, ADSP-2164 , ADSP-2165 or ADSP2166 processor, you must: 1. Complete the following forms contained in the ADSP ROM Ordering Package, available from your Analog Devices sales representative: ADSP-216x ROM Specification Form ROM Release Agreement ROM NRE Agreement & Minimum Quantity Order (MQO) Acceptance Agreement for Preproduction ROM Products 2. Return the forms to Analog Devices along with two copies of the Memory Image File (.EXE file) of your ROM code. The files must be supplied on two 3.5" or 5.25" floppy disks for the IBM PC (DOS 2.01 or higher). 3. Place a purchase order with Analog Devices for nonrecurring engineering changes (NRE) associated with ROM product development. After this information is received, it is entered into Analog Devices' ROM Manager System which assigns a custom ROM model number to the product. This model number will be branded on all prototype and production units manufactured to these specifications. To minimize the risk of code being altered during this process, Analog Devices verifies that the .EXE files on both floppy disks are identical, and recalculates the checksums for the .EXE file entered into the ROM Manager System. The checksum data, in the form of a ROM Memory Map, a hard copy of the .EXE file, and a ROM Data Verification form are returned to you for inspection. A signed ROM Verification Form and a purchase order for production units are required prior to any product being manufactured. Prototype units may be applied toward the minimum order quantity. Upon completion of prototype manufacture, Analog Devices will ship prototype units and a delivery schedule update for production units. An invoice against your purchase order for the NRE charges is issued at this time. There is a charge for each ROM mask generated and a minimum order quantity. Consult your sales representative for details. A separate order must be placed for parts of a specific package type, temperature range, and speed grade. -10- REV. 0 The IDLE instruction places the ADSP-216x processor in low power state in which it waits for an interrupt. When an interrupt occurs, it is serviced and execution continues with instruction following IDLE. Typically this next instruction will be a JUMP back to the IDLE instruction. This implements a low power standby loop. The IDLE n instruction is a special version of IDLE that slows the processor's internal clock signal to further reduce power consumption. The reduced clock frequency, a programmable fraction of the normal clock rate, is specified by a selectable divisor, n, given in the IDLE instruction. The syntax of the instruction is: IDLE n; where n = 16, 32, 64 or 128. The instruction leaves the chip in an idle state, operating at the slower rate. While it is in this state, the processor's other internal clock signals, such as SCLK, CLKOUT, and the timer clock, are reduced by the same ratio. Upon receipt of an enabled interrupt, the processor will stay in the IDLE state for up to a maximum of n CLKIN cycles, where n is the divisor specified in the instruction, before resuming normal operation. When the IDLE n instruction is used, it slows the processor's internal clock and thus its response time to incoming interrupts- the 1-cycle response time of the standard IDLE state is increased by n, the clock divisor. When an enabled interrupt is received, the ADSP-216x will remain in the IDLE state for up to a maximum of n CLKIN cycles (where n = 16, 32, 64 or 128) before resuming normal operation. When the IDLE n instruction is used in systems that have an externally generated serial clock (SCLK), the serial clock rate may be faster than the processor's reduced internal clock rate. Under these conditions, interrupts must not be generated at a faster rate than can be serviced, due to the additional time the processor takes to come out of the IDLE state (a maximum of n CLKIN cycles). ADSP-216x Instruction Set The ADSP-216x assembly language uses an algebraic syntax for ease of coding and readability. The sources and destinations of computations and data movements are written explicitly in each assembly statement, eliminating cryptic assembler mnemonics. Every instruction assembles into a single 24-bit word and executes in a single cycle. The instructions encompass a wide variety of instruction types along with a high degree of operational ALU Instructions parallelism. There are five basic categories of instructions: data move instructions, computational instructions, multifunction instructions, program flow control instructions and miscellaneous instructions. Multifunction instructions perform one or two data moves and a computation. The instruction set is summarized below. The ADSP-2100 Family Users Manual contains a complete reference to the instruction set.

The output enable time (tENA) is the interval from when a reference signal reaches a high or low voltage level to when the output has reached a specified high or low trip point, as shown in Figure 13.

Section 10.2.4, "Bus Request/Grant," of the ADSP-2100 Family User's Manual, Third Edition, states that, "When BR is recognized, the processor responds immediately by asserting BG during the same cycle." This is incorrect for the current versions of all ADSP-21xx processors: BG is asserted in the cycle after BR is recognized.
