The device enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, and high processing performance life through the maximum flexibility of a fully integrated mixed processor solution. The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously. The ARM core has a coprocessor 15 (CP15), protection module, and Data and program Memory Management Units (MMUs) with table look-aside buffers. It has separate 16K-byte instruction and 16K-byte data caches. Both are four-way associative with virtual index virtual tag (VIVT). The ARM core also has a 8KB RAM (Vector Table) and 64KB ROM. ADVANCE INFORMATION The peripheral set includes: a 10/100 Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output (MDIO) module; one USB2.0 OTG interface; one USB1.1 OHCI interface; two inter-integrated circuit (I2C) Bus interfaces; one multichannel audio serial port (McASP) with 16 serializers and FIFO buffers; two multichannel buffered serial ports (McBSP) with FIFO buffers; two SPI interfaces with multiple chip selects; four 64-bit general-purpose timers each configurable (one configurable as watchdog); a configurable 16-bit host port interface (HPI) ; up to 9 banks of 16 pins of general-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; three UART interfaces (each with RTS and CTS); two enhanced high-resolution pulse width modulator (eHRPWM) peripherals; 3 32-bit enhanced capture (eCAP) module peripherals which can be configured as 3 capture inputs or 3 auxiliary pulse width modulator (APWM) outputs; and 2 external memory interfaces: an asynchronous and SDRAM external memory interface (EMIFA) for slower memories or peripherals, and a higher speed DDR2/Mobile DDR controller. The Ethernet Media Access Controller (EMAC) provides an efficient interface between the device and a network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode.

Characteristic data and other specifications are subject to change without notice. 3.2 Device Compatibility The ARM926EJ-S RISC CPU is compatible with other ARM9 CPUs from ARM Holdings plc. ARM Subsystem The ARM Subsystem includes the following features: • ARM926EJ-S RISC processor • ARMv5TEJ (32/16-bit) instruction set • Little endian • System Control Co-Processor 15 (CP15) • MMU • 16KB Instruction cache • 16KB Data cache • Write Buffer • Embedded Trace Module and Embedded Trace Buffer (ETM/ETB) • ARM Interrupt controller 3.3.1 ARM926EJ-S RISC CPU The ARM Subsystem integrates the ARM926EJ-S processor. The ARM926EJ-S processor is a member of ARM9 family of general-purpose microprocessors. This processor is targeted at multi-tasking applications where full memory management, high performance, low die size, and low power are all important. The ARM926EJ-S processor supports the 32-bit ARM and 16 bit THUMB instruction sets, enabling the user to trade off between high performance and high code density. Specifically, the ARM926EJ-S processor supports the ARMv5TEJ instruction set, which includes features for efficient execution of Java byte codes, providing Java performance similar to Just in Time (JIT) Java interpreter, but without associated code overhead. The ARM926EJ-S processor supports the ARM debug architecture and includes logic to assist in both hardware and software debug. The ARM926EJ-S processor has a Harvard architecture and provides a complete high performance subsystem, including: • ARM926EJ -S integer core • CP15 system control coprocessor • Memory Management Unit (MMU) • Separate instruction and data caches • Write buffer • Separate instruction and data (internal RAM) interfaces • Separate instruction and data AHB bus interfaces • Embedded Trace Module and Embedded Trace Buffer (ETM/ETB) For more complete details on the ARM9, refer to the ARM926EJ-S Technical Reference Manual, available at http://www.arm.com Device Overview Copyright © 2010, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AM1808 9 ADVANCE INFORMATION 3.3 AM1808 SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 3.3.2 www.ti.com CP15 The ARM926EJ-S system control coprocessor (CP15) is used to configure and control instruction and data caches, Memory Management Unit (MMU), and other ARM subsystem functions. The CP15 registers are programmed using the MRC and MCR ARM instructions, when the ARM in a privileged mode such as supervisor or system mode. 3.3.3 MMU ADVANCE INFORMATION A single set of two level page tables stored in main memory is used to control the address translation, permission checks and memory region attributes for both data and instruction accesses. The MMU uses a single unified Translation Lookaside Buffer (TLB) to cache the information held in the page tables. The MMU features are: • Standard ARM architecture v4 and v5 MMU mapping sizes, domains and access protection scheme. • Mapping sizes are: – 1MB (sections) – 64KB (large pages) – 4KB (small pages) – 1KB (tiny pages) • Access permissions for large pages and small pages can be specified separately for each quarter of the page (subpage permissions) • Hardware page table walks • Invalidate entire TLB, using CP15 register 8 • Invalidate TLB entry, selected by MVA, using CP15 register 8 • Lockdown of TLB entries, using CP15 register 10 3.3.4 Caches and Write Buffer The size of the Instruction cache is 16KB, Data cache is 16KB. Additionally, the caches have the following features: • Virtual index, virtual tag, and addressed using the Modified Virtual Address (MVA) • Four-way set associative, with a cache line length of eight words per line (32-bytes per line) and with two dirty bits in the Dcache • Dcache supports write-through and write-back (or copy back) cache operation, selected by memory region using the C and B bits in the MMU translation tables • Critical-word first cache refilling • Cache lockdown registers enable control over which cache ways are used for allocation on a line fill, providing a mechanism for both lockdown, and controlling cache corruption • Dcache stores the Physical Address TAG (PA TAG) corresponding to each Dcache entry in the TAG RAM for use during the cache line write-backs, in addition to the Virtual Address TAG stored in the TAG RAM. This means that the MMU is not involved in Dcache write-back operations, removing the possibility of TLB misses related to the write-back address. • Cache maintenance operations provide efficient invalidation of, the entire Dcache or Icache, regions of the Dcache or Icache, and regions of virtual memory. The write buffer is used for all writes to a noncachable bufferable region, write-through region and write misses to a write-back region. A separate buffer is incorporated in the Dcache for holding write-back for cache line evictions or cleaning of dirty cache lines. The main write buffer has 16-word data buffer and a four-address buffer. The Dcache write-back has eight data word entries and a single address entry. 10 Device Overview Copyright © 2010, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AM1808 AM1808 www.ti.com 3.3.5 SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 Advanced High-Performance Bus (AHB) The ARM Subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the Config bus and the external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB by the Config Bus and the external memories bus. 3.3.6 Embedded Trace Macrocell (ETM) and Embedded Trace Buffer (ETB) To support real-time trace, the ARM926EJ-S processor provides an interface to enable connection of an Embedded Trace Macrocell (ETM). The ARM926ES-J Subsystem in the AM1808 also includes the Embedded Trace Buffer (ETB). The ETM consists of two parts: • Trace Port provides real-time trace capability for the ARM9. • Triggering facilities provide trigger resources, which include address and data comparators, counter, and sequencers. 3.3.7 ARM Memory Mapping By default the ARM has access to most on and off chip memory areas, including EMIFA, DDR2, and the additional 128K byte on chip SRAM. Likewise almost all of the on chip peripherals are accessible to the ARM by default. See Table 3-2 for a detailed top level device memory map that includes the ARM memory space. Device Overview Copyright © 2010, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AM1808 11 ADVANCE INFORMATION The AM1808 trace port is not pinned out and is instead only connected to the Embedded Trace Buffer.

Pin Map (Quad D) 3.6 Pin Multiplexing Control Device level pin multiplexing is controlled by registers PINMUX0 - PINMUX19 in the SYSCFG module. For the device family, pin multiplexing can be controlled on a pin-by-pin basis. Each pin that is multiplexed with several different functions has a corresponding 4-bit field in one of the PINMUX registers. Pin multiplexing selects which of several peripheral pin functions controls the pin's IO buffer output data and output enable values only. The default pin multiplexing control for almost every pin is to select 'none' of the peripheral functions in which case the pin's IO buffer is held tri-stated. Note that the input from each pin is always routed to all of the peripherals that share the pin; the PINMUX registers have no effect on input from a pin. 18 Device Overview Copyright © 2010, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): AM1808 AM1808 www.ti.com 3.7 SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 Terminal Functions Table 3-3 to Table 3-29 identify the external signal names, the associated pin/ball numbers along with the mechanical package designator, the pin type (I, O, IO, OZ, or PWR), whether the pin/ball has any internal pullup/pulldown resistors, whether the pin/ball is configurable as an IO in GPIO mode, and a functional pin description. 3.7.1 Device Reset and JTAG Table 3-3.

IPD = Internal Pulldown resistor; IPU = Internal Pullup resistor; CP[n] = configurable pull-up/pull-down (where n is the pin group) using the PUPDENA and PUPDSEL registers in the System Module. The pull-up and pull-down control of these pins is not active until the device is out of reset. During reset, all of the pins associated with these registers are weakly pulled down. If the application requires a pull-up, an external pull-up can be used. This signal is part of a dual-voltage IO group (A, B or C). These groups can be operated at 3.3V or 1.8V nominal. The three groups can be operated at independent voltages but all pins withina group will operate at the same voltage. Group A operates at the voltage of power supply DVDD3318_A. Group B operates at the voltage of power supply DVDD3318_B. Group C operates at the voltage of power supply DVDD3318_C.

Note: The pin type shown refers to the input, output or high-impedance state of the pin function when configured as the signal name highlighted in bold. All multiplexed signals may enter a high-impedance state when the configured function is input-only or the configured function supports high-Z operation. All GPIO signals can be used as input or output. For multiplexed pins where functions have different types (ie., input versus output), the table reflects the pin function direction for that particular peripheral. IPD = Internal Pulldown resistor; IPU = Internal Pullup resistor; CP[n] = configurable pull-up/pull-down (where n is the pin group) using the PUPDENA and PUPDSEL registers in the System Module. The pull-up and pull-down control of these pins is not active until the device is out of reset. During reset, all of the pins associated with these registers are weakly pulled down. If the application requires a pull-up, an external pull-up can be used. This signal is part of a dual-voltage IO group (A, B or C). These groups can be operated at 3.3V or 1.8V nominal. The three groups can be operated at independent voltages but all pins withina group will operate at the same voltage. Group A operates at the voltage of power supply DVDD3318_A. Group B operates at the voltage of power supply DVDD3318_B. Group C operates at the voltage of power supply DVDD3318_C.

This device does not support dedicated hardware boot modes. The input states of the BOOT pins are sampled and latched into the BOOTCFG register, which is part of the system configuration (SYSCFG) module, when device reset is deasserted. Boot mode selection is determined by the values of the BOOT pins. See Using the OMAP-L1x8 Bootloader Application Report (SPRAB41) for more details on the ROM Boot Loader. 4.2 ADVANCE INFORMATION The following boot modes are supported: • NAND Flash boot – 8-bit NAND • NOR Flash boot – NOR Direct boot (8-bit or 16-bit) – NOR Legacy boot (8-bit or 16-bit) – NOR AIS boot (8-bit or 16-bit) • HPI Boot • I2C0/I2C1 Boot – EEPROM (Master Mode) – External Host (Slave Mode) • SPI0/ SPI1 Boot – Serial Flash (Master Mode) – SERIAL EEPROM (Master Mode) – External Host (Slave Mode) • UART0/UART1/UART2 Boot – External Host SYSCFG Module The following system level features of the chip are controlled by the SYSCFG peripheral: • Readable Device, Die, and Chip Revision ID • Control of Pin Multiplexing • Priority of bus accesses different bus masters in the system • Capture at power on reset the chip BOOT pin values and make them available to software • Control of the DeepSleep power management function • Enable and selection of the programmable pin pullups and pulldowns • Special case settings for peripherals: – Locking of PLL controller settings – Default burst sizes for EDMA3 transfer controllers – Selection of the source for the eCAP module input capture (including on chip sources) – McASP AMUTEIN selection and clearing of AMUTE status for the McASP – Control of the reference clock source and other side-band signals for both of the integrated USB PHYs – Clock source selection for EMIFA – DDR2 Controller PHY settings – SATA PHY power management controls • Selects the source of emulation suspend signal (from ARM) of peripherals supporting this function.

This may be achieved via pullup/pulldown resistors. The device features internal pullup (IPU) and internal pulldown (IPD) resistors on most pins to eliminate the need, unless otherwise noted, for external pullup/pulldown resistors. An external pullup/pulldown resistor needs to be used in the following situations: • Boot and Configuration Pins: If the pin is both routed out and 3-stated (not driven), an external pullup/pulldown resistor is strongly recommended, even if the IPU/IPD matches the desired value/state. • Other Input Pins: If the IPU/IPD does not match the desired value/state, use an external pullup/pulldown resistor to pull the signal to the opposite rail. For the boot and configuration pins, if they are both routed out and 3-stated (not driven), it is strongly recommended that an external pullup/pulldown resistor be implemented. Although, internal pullup/pulldown resistors exist on these pins and they may match the desired configuration value, providing external connectivity can help ensure that valid logic levels are latched on these device boot and configuration pins. In addition, applying external pullup/pulldown resistors on the boot and configuration pins adds convenience to the user in debugging and flexibility in switching operating modes. ADVANCE INFORMATION Tips for choosing an external pullup/pulldown resistor: • Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure to include the leakage currents of all the devices connected to the net, as well as any internal pullup or pulldown resistors. • Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of all inputs connected to the net. For a pullup resistor, this should be above the highest VIH level of all inputs on the net. A reasonable choice would be to target the VOL or VOH levels for the logic family of the limiting device; which, by definition, have margin to the VIL and VIH levels. • Select a pullup/pulldown resistor with the largest possible value; but, which can still ensure that the net will reach the target pulled value when maximum current from all devices on the net is flowing through the resistor. The current to be considered includes leakage current plus, any other internal and external pullup/pulldown resistors on the net. • For bidirectional nets, there is an additional consideration which sets a lower limit on the resistance value of the external resistor.

Clock PLLs The device has two PLL controllers that provide clocks to different parts of the system. PLL0 provides clocks (though various dividers) to most of the components of the device. PLL1 provides clocks to the mDDR/DDR2 Controller and provides an alternate clock source for the ASYNC3 clock domain. This allows the peripherals on the ASYNC3 clock domain to be immune to frequency scaling operation on PLL0.

ADVANCE INFORMATION 6.6.2 Device Clock Generation PLL0 is controlled by PLL Controller 0 and PLL1 is controlled by PLL Controller 1. PLLC0 and PLLC1 manage the clock ratios, alignment, and gating for the system clocks to the chip. The PLLCs are responsible for controlling all modes of the PLL through software, in terms of pre-division of the clock inputs (PLLC0 only), multiply factors within the PLLs, and post-division for each of the chip-level clocks from the PLLs outputs. PLLC0 also controls reset propagation through the chip, clock alignment, and test points. PLLC0 provides clocks for the majority of the system but PLLC1 provides clocks to the mDDR/DDR2 Controller and the ASYNC3 clock domain to provide frequency scaling immunity to a defined set or peripherals. The ASYNC3 clock domain can either derive its clock from PLL1_SYSCLK2 (for frequency scaling immunity from PLL0) or from PLL0_SYSCLK2 (for synchronous timing with PLL0) depending on the application requirements. In addition, some peripherals have specific clock options independent of the ASYNC clock domain. 6.6.3 Dynamic Voltage and Frequency Scaling (DVFS) The processor supports multiple operating points by scaling voltage and frequency to minimize power consumption for a given level of processor performance. Frequency scaling is achieved by modifying the setting of the PLL controllers’ multipliers, post-dividers (POSTDIV), and system clock dividers (SYSCLKn). Modification of the POSTDIV and SYSCLK values does not require relocking the PLL and provides lower latency to switch between operating points, but at the expense of the frequencies being limited by the integer divide values (only the divide values are altered the PLL multiplier is left unmodified). Non integer divide frequency values can be achieved by changing both the multiplier and the divide values, but when the PLL multiplier is changed the PLL must relock, incurring additional latency to change between operating points. Detailed information on modifying the PLL Controller settings can be found in SPRUGM9 - AM1808 ARM Microprocessor System Reference Guide . Voltage scaling is enabled from outside the device by controlling an external voltage regulator. The processor may communicate with the regulator using GPIOs, I2C or some other interface. When switching between voltage-frequency operating points, the voltage must always support the desired frequency. When moving from a high-performance operating point to a lower performance operating point, the frequency should be lowered first followed by the voltage. When moving from a low-performance operating point to a higher performance operating point, the voltage should be raised first followed by the frequency. Voltage operating points refer to the CVdd voltage at that point. Other static supplies must be maintained at their nominal voltages at all operating points. 78 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): AM1808 Copyright © 2010, Texas Instruments Incorporated AM1808 www.ti.com SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 The maximum voltage slew rate for CVdd supply changes is 1 mV/us.

PLL0_SYSCLK2:PLL0_SYSCLK4:PLL0_SYSCLK6 are synchronous to each other and the SYSCLKn dividers must always be configured such that the ratio between these domains is 2:4:1. The ASYNC and ASYNC3 clock domains are asynchronous to the other clock domains and have no specific ratio requirement. The table below summarizes the maximum internal clock frequencies at each of the voltage operating points.

See the corresponding peripheral sections of this document for more information. TI provides software components (called the Power Manager) to perform DVFS and abstract the task from the user. The Power Manager controls changing operating points (both frequency and voltage) and handles the related tasks involved such as informing/controlling peripherals to provide graceful transitions between operating points.

Maximum Internal Clock Frequencies at Each Voltage Operating Point AM1808 SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 6.7 www.ti.com Interrupts 6.7.1 ARM CPU Interrupts The ARM9 CPU core supports 2 direct interrupts: FIQ and IRQ. The ARM Interrupt Controller (AINTC) extends the number of interrupts to 100, and provides features like programmable masking, priority, hardware nesting support, and interrupt vector generation. 6.7.1.1 ARM Interrupt Controller (AINTC) Interrupt Signal Hierarchy ADVANCE INFORMATION The ARM Interrupt controller organizes interrupts into the following hierarchy: • Peripheral Interrupt Requests – Individual Interrupt Sources from Peripherals • 101 System Interrupts – One or more Peripheral Interrupt Requests are combined (fixed configuration) to generate a System Interrupt. – After prioritization, the AINTC will provide an interrupt vector based unique to each System Interrupt • 32 Interrupt Channels – Each System Interrupt is mapped to one of the 32 Interrupt Channels – Channel Number determines the first level of prioritization, Channel 0 is highest priority and 31 lowest. – If more than one system interrupt is mapped to a channel, priority within the channel is determined by system interrupt number (0 highest priority) • Host Interrupts (FIQ and IRQ) – Interrupt Channels 0 and 1 generate the ARM FIQ interrupt – Interrupt Channels 2 through 31 Generate the ARM IRQ interrupt • Debug Interrupts – Two Debug Interrupts are supported and can be used to trigger events in the debug subsystem – Sources can be selected from any of the System Interrupts or Host Interrupts 6.7.1.2 AINTC Hardware Vector Generation The AINTC also generates an interrupt vector in hardware for both IRQ and FIQ host interrupts. This may be used to accelerate interrupt dispatch. A unique vector is generated for each of the 100 system interrupts. The vector is computed in hardware as: VECTOR = BASE + (SYSTEM INTERRUPT NUMBER × SIZE) Where BASE and SIZE are programmable. The computed vector is a 32-bit address which may dispatched to using a single instruction of type LDR PC, [PC, #-<offset_12>] at the FIQ and IRQ vector locations (0xFFFF0018 and 0xFFFF001C respectively). 6.7.1.3 AINTC Hardware Interrupt Nesting Support Interrupt nesting occurs when an interrupt service routine re-enables interrupts, to allow the CPU to interrupt the ISR if a higher priority event occurs. The AINTC provides hardware support to facilitate interrupt nesting. It supports both global and per host interrupt (FIQ and IRQ in this case) automatic nesting. If enabled, the AINTC will automatically update an internal nesting register that temporarily masks interrupts at and below the priority of the current interrupt channel. Then if the ISR re-enables interrupts; only higher priority channels will be able to interrupt it. The nesting level is restored by the ISR by writing to the nesting level register on completion. Support for nesting can be enabled/disabled by software, with the option of automatic nesting on a global or per host interrupt basis; or manual nesting. 6.7.1.4 AINTC System Interrupt Assignments System Interrupt assignments are listed in Table 6-6 80 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): AM1808 Copyright © 2010, Texas Instruments Incorporated AM1808 www.ti.com SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 System Interrupt Interrupt Name Source 0 COMMTX ARM 1 COMMRX ARM 2 NINT ARM 3 PRU_EVTOUT0 PRUSS Interrupt 4 PRU_EVTOUT1 PRUSS Interrupt 5 PRU_EVTOUT2 PRUSS Interrupt 6 PRU_EVTOUT3 PRUSS Interrupt 7 PRU_EVTOUT4 PRUSS Interrupt 8 PRU_EVTOUT5 PRUSS Interrupt 9 PRU_EVTOUT6 PRUSS Interrupt 10 PRU_EVTOUT7 PRUSS Interrupt 11 EDMA3_0_CC0_INT0 EDMA3_0 Channel Controller 0 Shadow Region 0 Transfer Completion Interrupt 12 EDMA3_0_CC0_ERRINT EDMA3_0 Channel Controller 0 Error Interrupt 13 EDMA3_0_TC0_ERRINT EDMA3_0 Transfer Controller 0 Error Interrupt 14 EMIFA_INT EMIFA 15 IIC0_INT I2C0 16 MMCSD0_INT0 MMCSD0 MMC/SD Interrupt 17 MMCSD0_INT1 MMCSD0 SDIO Interrupt 18 PSC0_ALLINT PSC0 19 RTC_IRQS[1:0] RTC 20 SPI0_INT SPI0 21 T64P0_TINT12 Timer64P0 Interrupt 12 22 T64P0_TINT34 Timer64P0 Interrupt 34 23 T64P1_TINT12 Timer64P1 Interrupt 12 24 T64P1_TINT34 Timer64P1 Interrupt 34 25 UART0_INT UART0 26 - Reserved 27 PROTERR SYSCFG Protection Shared Interrupt 28 - Reserved 29 - Reserved 30 - Reserved 31 - Reserved 32 EDMA3_0_TC1_ERRINT EDMA3_0 Transfer Controller 1 Error Interrupt 33 EMAC_C0RXTHRESH EMAC - Core 0 Receive Threshold Interrupt 34 EMAC_C0RX EMAC - Core 0 Receive Interrupt 35 EMAC_C0TX EMAC - Core 0 Transmit Interrupt 36 EMAC_C0MISC EMAC - Core 0 Miscellaneous Interrupt 37 EMAC_C1RXTHRESH EMAC - Core 1 Receive Threshold Interrupt 38 EMAC_C1RX EMAC - Core 1 Receive Interrupt 39 EMAC_C1TX EMAC - Core 1 Transmit Interrupt 40 EMAC_C1MISC EMAC - Core 1 Miscellaneous Interrupt 40 DDR2_MEMERR DDR2 Controller 42 GPIO_B0INT GPIO Bank 0 Interrupt 43 GPIO_B1INT GPIO Bank 1 Interrupt 44 GPIO_B2INT GPIO Bank 2 Interrupt 45 GPIO_B3INT GPIO Bank 3 Interrupt Copyright © 2010, Texas Instruments Incorporated Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): AM1808 ADVANCE INFORMATION Table 6-6.

It is used primarily to provide granular power control for on chip modules (peripherals and CPU). A PSC module consists of a Global PSC (GPSC) and a set of Local PSCs (LPSCs). The GPSC contains memory mapped registers, PSC interrupts, a state machine for each peripheral/module it controls. An LPSC is associated with every module that is controlled by the PSC and provides clock and reset control. The PSC includes the following features: • Provides a software interface to: – Control module clock enable/disable – Control module reset – Control CPU local reset • Supports IcePick emulation features: power, clock and reset PSC0 controls 16 local PSCs. PSC1 controls 32 local PSCs. ADVANCE INFORMATION Table 6-8.

PSC1 Default Module Configuration 89 AM1808 SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 6.8.1.1 www.ti.com Module States The PSC defines several possible states for a module. This states are essentially a combination of the module reset asserted or de-asserted and module clock on/enabled or off/disabled. The module states are defined in Table 6-11. Table 6-11. Module States ADVANCE INFORMATION Module State Module Reset Module Clock Module State Definition Enable De-asserted On A module in the enable state has its module reset de-asserted and it has its clock on. This is the normal operational state for a given module Disable De-asserted Off A module in the disabled state has its module reset de-asserted and it has its module clock off. This state is typically used for disabling a module clock to save power. The device is designed in full static CMOS, so when you stop a module clock, it retains the module’s state. When the clock is restarted, the module resumes operating from the stopping point. SyncReset Asserted On A module state in the SyncReset state has its module reset asserted and it has its clock on. Generally, software is not expected to initiate this state SwRstDisable Asserted Off A module in the SwResetDisable state has its module reset asserted and it has its clock disabled. After initial power-on, several modules come up in the SwRstDisable state. Generally, software is not expected to initiate this state Auto Sleep De-asserted Off A module in the Auto Sleep state also has its module reset de-asserted and its module clock disabled, similar to the Disable state. However this is a special state, once a module is configured in this state by software, it can “automatically” transition to “Enable” state whenever there is an internal read/write request made to it, and after servicing the request it will “automatically” transition into the sleep state (with module reset re de-asserted and module clock disabled), without any software intervention. The transition from sleep to enabled and back to sleep state has some cycle latency associated with it. It is not envisioned to use this mode when peripherals are fully operational and moving data. Auto Wake De-asserted Off A module in the Auto Wake state also has its module reset de-asserted and its module clock disabled, similar to the Disable state. However this is a special state, once a module is configured in this state by software, it will “automatically” transition to “Enable” state whenever there is an internal read/write request made to it, and will remain in the “Enabled” state from then on (with module reset re de-asserted and module clock on), without any software intervention. The transition from sleep to enabled state has some cycle latency associated with it. It is not envisioned to use this mode when peripherals are fully operational and moving data. 90 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): AM1808 Copyright © 2010, Texas Instruments Incorporated AM1808 www.ti.com 6.9 SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 EDMA The EDMA controller handles all data transfers between memories and the device slave peripherals on the device.

It is primarily intended to support asynchronous memory types, such as NAND and NOR flash and Asynchronous SRAM. However on this device, EMIFA also provides a secondary interface to SDRAM. 6.10.1 EMIFA Asynchronous Memory Support EMIFA supports asynchronous: • SRAM memories • NAND Flash memories • NOR Flash memories Each chip select has the following individually programmable attributes: • Data Bus Width • Read cycle timings: setup, hold, strobe • Write cycle timings: setup, hold, strobe • Bus turn around time • Extended Wait Option With Programmable Timeout • Select Strobe Option • NAND flash controller supports 1-bit and 4-bit ECC calculation on blocks of 512 bytes. 6.10.2 EMIFA Synchronous DRAM Memory Support The device supports 16-bit SDRAM in addition to the asynchronous memories listed in Section 6.10.1. It has a single SDRAM chip select (EMA_CS[0]). SDRAM configurations that are supported are: • One, Two, and Four Bank SDRAM devices • Devices with Eight, Nine, Ten, and Eleven Column Address • CAS Latency of two or three clock cycles • Sixteen Bit Data Bus Width Additionally, the SDRAM interface of EMIFA supports placing the SDRAM in Self Refresh and Powerdown Modes. Self Refresh mode allows the SDRAM to be put into a low power state while still retaining memory contents; since the SDRAM will continue to refresh itself even without clocks from the device. Powerdown mode achieves even lower power, except the device must periodically wake the SDRAM up and issue refreshes if data retention is required. Finally, note that the EMIFA does not support Mobile SDRAM devices. Table 6-17 shows the supported SDRAM configurations for EMIFA. Copyright © 2010, Texas Instruments Incorporated Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): AM1808 97 ADVANCE INFORMATION The EMIFA data bus width is up to 16-bits.The device supports up to 24 address lines and two external wait/interrupt inputs. Up to four asynchronous chip selects are supported by EMIFA (EMA_CS[5:2]). AM1808 SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 www.ti.com Table 6-17.

Additional loads will limit the SDRAM operation to lower speeds and the maximum speed should be confirmed by board simulation using IBIS models. 98 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): AM1808 Copyright © 2010, Texas Instruments Incorporated AM1808 www.ti.com SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 6.10.4 External Memory Interface Register Descriptions Table 6-18 is a list of the EMIF registers.

Instead, the boundary scan cells are tapped-off to the DDR PHY and there is the equivalent of a multiplexer inside the DDR PHY which selects between functional and boundary scan paths. The implication for boundary scan is that the DDR pins will not support the SAMPLE function of the output enable cells on the DDR pins and this is a violation of IEEE 1149.1. Full EXTEST and PRELOAD capability is still available.

It receives requests from a bus master in the system and checks the address against the fixed and programmable regions to see if the access is allowed. If allowed, the transfer is passed unmodified to its output bus (to the targeted address). If the transfer is illegal (fails the protection check) then the MPU does not pass the transfer to the output bus but rather services the transfer internally back to the input bus (to prevent a hang) returning the fault status to the requestor as well as generating an interrupt about the fault. The following features are supported by the MPU: • Provides memory protection for fixed and programmable address ranges. • Supports multiple programmable address region. • Supports secure and debug access privileges. • Supports read, write, and execute access privileges. • Supports privid(8) associations with ranges. • Generates an interrupt when there is a protection violation, and saves violating transfer parameters. • MMR access is also protected.

Minimum CLKR/X cycle times must be met, even when CLKR/X is generated by an internal clock source. Minimum CLKR/X cycle times are based on internal logic speed; the maximum usable speed may be lower due to EDMA limitations and AC timing requirements. P = AYNC3 period in ns.

Data is written to the shift register before transmission occurs and is read from the buffer at the end of transmission. The SPI can operate either as a master, in which case, it initiates a transfer and drives the SPIx_CLK pin, or as a slave. Four clock phase and polarity options are supported as well as many data formatting options. SPIx_SIMO SPIx_SOMI Peripheral Configuration Bus Interrupt and DMA Requests 16-Bit Shift Register 16-Bit Buffer SPIx_ENA State GPIO Machine SPIx_SCS Control (all pins) Clock SPIx_CLK Control ADVANCE INFORMATION Figure 6-34. Block Diagram of SPI Module The SPI supports 3-, 4-, and 5-pin operation with three basic pins (SPIx_CLK, SPIx_SIMO, and SPIx_SOMI) and two optional pins (SPIx_SCS, SPIx_ENA). The optional SPIx_SCS (Slave Chip Select) pin is most useful to enable in slave mode when there are other slave devices on the same SPI port. The device will only shift data and drive the SPIx_SOMI pin when SPIx_SCS is held low. In slave mode, SPIx_ENA is an optional output and can be driven in either a push-pull or open-drain manner. The SPIx_ENA output provides the status of the internal transmit buffer (SPIDAT0/1 registers). In four-pin mode with the enable option, SPIx_ENA is asserted only when the transmit buffer is full, indicating that the slave is ready to begin another transfer. In five-pin mode, the SPIx_ENA is additionally qualified by SPIx_SCS being asserted. This allows a single handshake line to be shared by multiple slaves on the same SPI bus. In master mode, the SPIx_ENA pin is an optional input and the master can be configured to delay the start of the next transfer until the slave asserts SPIx_ENA. The addition of this handshake signal simplifies SPI communications and, on average, increases SPI bus throughput since the master does not need to delay each transfer long enough to allow for the worst-case latency of the slave device. Instead, each transfer can begin as soon as both the master and slave have actually serviced the previous SPI transfer. 150 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): AM1808 Copyright © 2010, Texas Instruments Incorporated AM1808 www.ti.com SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 Optional − Slave Chip Select SPIx_SCS SPIx_SCS SPIx_ENA SPIx_ENA SPIx_CLK SPIx_CLK SPIx_SOMI SPIx_SOMI SPIx_SIMO SPIx_SIMO MASTER SPI SLAVE SPI ADVANCE INFORMATION Optional Enable (Ready) Figure 6-35.

The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS) support. The EMAC controls the flow of packet data from the device to the PHY. The MDIO module controls PHY configuration and status monitoring. Both the EMAC and the MDIO modules interface to the device through a custom interface that allows efficient data transmission and reception. This custom interface is referred to as the EMAC control module, and is considered integral to the EMAC/MDIO peripheral. The control module is also used to multiplex and control interrupts. 6.22.1 EMAC Peripheral Register Description(s) Table 6-94.

The Management Data Input/Output (MDIO) module implements the 802.3 serial management interface to interrogate and control Ethernet PHY(s) using a shared two-wire bus. Host software uses the MDIO module to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve the negotiation results, and configure required parameters in the EMAC module for correct operation. The module is designed to allow almost transparent operation of the MDIO interface, with very little maintenance from the core processor. Only one PHY may be connected at any given time. 6.23.1 MDIO Registers For a list of supported MDIO registers see Table 6-104 [MDIO Registers]. Table 6-104.

Each controller operates independently from the other and only one of them is active at any given time. • The Raster Controller handles the synchronous LCD interface. It provides timing and data for constant graphics refresh to a passive display. It supports a wide variety of monochrome and full-color display types and sizes by use of programmable timing controls, a built-in palette, and a gray-scale/serializer. Graphics data is processed and stored in frame buffers. A frame buffer is a contiguous memory block in the system. A built-in DMA engine supplies the graphics data to the Raster engine which, in turn, outputs to the external LCD device. • The LIDD Controller supports the asynchronous LCD interface. It provides full-timing programmability of control signals (CS, WE, OE, ALE) and output data. Table 6-107 lists the LCD Controller registers. Table 6-107.

The host port interface (UHPI) provides a parallel port interface through which an external host processor can directly access the processor's resources (configuration and program/data memories). The external host device is asynchronous to the CPU clock and functions as a master to the HPI interface. The UHPI enables a host device and the processor to exchange information via internal or external memory. Dedicated address (HPIA) and data (HPID) registers within the UHPI provide the data path between the external host interface and the processor resources. A UHPI control register (HPIC) is available to the host and the CPU for various configuration and interrupt functions. 6.25.2 HPI Peripheral Register Description(s) Table 6-111.

Reserved 01E1 002C (1) COMMENTS Peripheral Identification Register The Host and the CPU both have read/write access to the HPIC register. The Host has read/write access to the HPIA registers. The CPU has only read access to the HPIA registers. Reserved There are two 32-bit HPIA registers: HPIAR for read operations and HPIAW for write operations. The HPI can be configured such that HPIAR and HPIAW act as a single 32-bit HPIA (single-HPIA mode) or as two separate 32-bit HPIAs (dual-HPIA mode) from the perspective of the Host. The CPU can access HPIAW and HPIAR independently.

It is designed to interface cleanly with high-speed analog-to-digital converters (ADCs) or digital-to-analog converters (DACs) with up to 16-bit data width (per channel). It may also be interconnected with field-programmable gate arrays (FPGAs) or other uPP devices to achieve high-speed digital data transfer. It can operate in receive mode, transmit mode, or duplex mode, in which its individual channels operate in opposite directions. The uPP peripheral includes an internal DMA controller to maximize throughput and minimize CPU overhead during high-speed data transmission. All uPP transactions use the internal DMA to provide data to or retrieve data from the I/O channels. The DMA controller includes two DMA channels, which typically service separate I/O channels. The uPP peripheral also supports data interleave mode, in which all DMA resources service a single I/O channel. In this mode, only one I/O channel may be used. ADVANCE INFORMATION The features of the uPP include: • Programmable data width per channel (from 8 to 16 bits inclusive) • Programmable data justification – Right-justify with zero extend – Right-justify with sign extend – Left-justify with zero fill • Supports multiplexing of interleaved data during SDR transmit • Optional frame START signal with programmable polarity • Optional data ENABLE signal with programmable polarity • Optional synchronization WAIT signal with programmable polarity • Single Data Rate (SDR) or Double data Rate (DDR, interleaved) interface – Supports multiplexing of interleaved data during SDR transmit – Supports demultiplexing and multiplexing of interleaved data during DDR transfers 220 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): AM1808 Copyright © 2010, Texas Instruments Incorporated AM1808 www.ti.com SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 6.26.1 uPP Register Descriptions Table 6-115 shows the uPP registers.

The current date and time is tracked in a set of counter registers that update once per second. The time can be represented in 12-hour or 24-hour mode. The calendar and time registers are buffered during reads and writes so that updates do not interfere with the accuracy of the time and date. The real-time clock (RTC) provides the following features: • 100-year calendar (xx00 to xx99) • Counts seconds, minutes, hours, day of the week, date, month, and year with leap year compensation • Binary-coded-decimal (BCD) representation of time, calendar, and alarm • 12-hour clock mode (with AM and PM) or 24-hour clock mode • Alarm interrupt • Periodic interrupt • Single interrupt to the CPU • Supports external 32.768-kHz crystal or external clock source of the same frequency • Separate isolated power supply Figure 6-82 shows a block diagram of the RTC.

In addition, the RTC can interrupt the CPU every time the calendar and time registers are updated, or at programmable periodic intervals. AM1808 SPRS653A – FEBRUARY 2010 – REVISED APRIL 2010 www.ti.com 6.31.1 Clock Source The clock reference for the RTC is an external 32.768-kHz crystal or an external clock source of the same frequency. The RTC also has a separate power supply that is isolated from the rest of the system. When the CPU and other peripherals are without power, the RTC can remain powered to preserve the current time and calendar information. Even if the RTC is not used, it must remain powered when the rest of the device is powered. The source for the RTC reference clock may be provided by a crystal or by an external clock source. The RTC has an internal oscillator buffer to support direct operation with a crystal. The crystal is connected between pins RTC_XI and RTC_XO. RTC_XI is the input to the on-chip oscillator and RTC_XO is the output from the oscillator back to the crystal. An external 32.768-kHz clock source may be used instead of a crystal. In such a case, the clock source is connected to RTC_XI, and RTC_XO is left unconnected. If the RTC is not used, the RTC_XI pin should be held either low or high, RTC_XO should be left unconnected, RTC_CVDD should be connected to the device CVDD and RTC_VSS should remain grounded.

When configured as an output, a write to an internal register can control the state driven on the output pin. When configured as an input, the state of the input is detectable by reading the state of an internal register. In addition, the GPIO peripheral can produce CPU interrupts and EDMA events in different interrupt/event generation modes. The GPIO peripheral provides generic connections to external devices. The GPIO pins are grouped into banks of 16 pins per bank (i.e., bank 0 consists of GPIO [0:15]). ADVANCE INFORMATION The device GPIO peripheral supports the following: • Up to 144 Pins configurable as GPIO • External Interrupt and DMA request Capability – Every GPIO pin may be configured to generate an interrupt request on detection of rising and/or falling edges on the pin. – The interrupt requests within each bank are combined (logical or) to create eight unique bank level interrupt requests. – The bank level interrupt service routine may poll the INTSTATx register for its bank to determine which pin(s) have triggered the interrupt. – GPIO Banks 0, 1, 2, 3, 4, 5, 6, 7 and 8 Interrupts assigned to ARM INTC Interrupt Requests 42, 43, 44, 45, 46, 47, 48, 49 and 50 respectively – GPIO Banks 0, 1, 2, 3, 4, and 5 are assigned to EDMA events 6, 7, 22, 23, 28, 29, and 29 respectively on Channel Controller 0 and GPIO Banks 6, 7, and 8 are assigned to EDMA events 16, 17, and 18 respectively on Channel Controller 1. • Set/clear functionality: Firmware writes 1 to corresponding bit position(s) to set or to clear GPIO signal(s). This allows multiple firmware processes to toggle GPIO output signals without critical section protection (disable interrupts, program GPIO, re-enable interrupts, to prevent context switching to anther process during GPIO programming). • Separate Input/Output registers • Output register in addition to set/clear so that, if preferred by firmware, some GPIO output signals can be toggled by direct write to the output register(s). • Output register, when read, reflects output drive status. This, in addition to the input register reflecting pin status and open-drain I/O cell, allows wired logic be implemented.

The INTC also supports posting events back to the device level host CPU. • A Switched Central Resource (SCR) for connecting the various internal and external masters to the resources inside the PRUSS. The two PRUs can operate completely independently or in coordination with each other. The PRUs can also work in coordination with the device level host CPU. This is determined by the nature of the program which is loaded into the PRUs instruction memory. Several different signaling mechanisms are available between the two PRUs and the device level host CPU. The PRUs are optimized for performing embedded tasks that require manipulation of packed memory mapped data structures, handling of system events that have tight realtime constraints and interfacing with systems external to the device. ADVANCE INFORMATION The PRUSS comprises various distinct addressable regions. Externally the subsystem presents a single 64Kbyte range of addresses. The internal interconnect bus (also called switched central resource, or SCR) of the PRUSS decodes accesses for each of the individual regions. The PRUSS memory map is documented in Table 6-138 and in Table 6-139. Note that these two memory maps are implemented inside the PRUSS and are local to the components of the PRUSS. Table 6-138.

Data RAM0 is intended to be the primary data memory for PRU0 and Data RAM1 is intended to be the primary data memory for PRU1. However for passing information between PRUs, each PRU can access the data ram of the ‘other’ PRU through address 0x0000 2000. The global view of the PRUSS internal memories and control ports is documented in Table 6-140. The offset addresses of each region are implemented inside the PRUSS but the global device memory mapping places the PRUSS slave port in the address range 0x01C3 0000-0x01C3 FFFF. The PRU0 and PRU1 can use either the local or global addresses to access their internal memories, but using the local addresses will provide access time several cycles faster than using the global addresses. This is because when accessing via the global address the access needs to be routed through the switch fabric outside PRUSS and back in through the PRUSS slave port. Table 6-140.

TRST holds the debug and boundary scan logic in reset when pulled low (its default state). Since TRST has an internal pull-down resistor, this ensures that at power up the device functions in its normal (non-test) operation mode if TRST is not connected. Otherwise, TRST should be driven inactive by the emulator or boundary scan controller. Boundary scan test cannot be performed while the TRST pin is pulled low. Table 6-144. JTAG Port Description PIN TYPE NAME DESCRIPTION TRST I Test Logic Reset When asserted (active low) causes all test and debug logic in the device to be reset along with the IEEE 1149.1 interface TCK I Test Clock This is the test clock used to drive an IEEE 1149.1 TAP state machine and logic. Depending on the emulator attached to , this is a free running clock or a gated clock depending on RTCK monitoring. RTCK O Returned Test Clock Synchronized TCK.

Each commercial AM1xxx platform member has one of three prefixes: X, P, or null (no prefix). Texas Instruments recommends two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMDX) through fully qualified production devices/tools (TMDS). Device development evolutionary flow: ADVANCE INFORMATION X Experimental device that is not necessarily representative of the final device's electrical specifications. P Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification. NULL Fully-qualified production device. Support tool development evolutionary flow: TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing. TMDS Fully qualified development-support product. X and P devices and TMDX development-support tools are shipped against the following disclaimer: "Developmental product is intended for internal evaluation purposes." NULL devices and TMDS development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI's standard warranty applies. Predictions show that prototype devices (X or P) have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used. Figure 8-1 provides a legend for reading the complete device.

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
