Architectural Overview The AT91R40008 microcontroller integrates an ARM7TDMI with EmbeddedICE interface, memories and peripherals. The architecture consists of two main buses: the Advanced System Bus (ASB) and the Advanced Peripheral Bus (APB). Designed for maximum performance and controlled by the memory controller, the ASB interfaces the ARM7TDMI processor with the on-chip 32-bit memories, the External Bus Interface (EBI) and the AMBA™ Bridge. The AMBA Bridge drives the APB, which is designed for accesses to on-chip peripherals and optimized for low power consumption. The AT91R40008 microcontroller implements the ICE port of the ARM7TDMI processor on dedicated pins, offering a complete, low-cost and easy-to-use debug solution for target debugging. 5.1 Memories The AT91R40008 microcontroller embeds 256K bytes of internal SRAM. The internal memory is directly connected to the 32-bit data bus and is single-cycle accessible. The AT91R40008 microcontroller features an External Bus Interface (EBI), which enables connection of external memories and application-specific peripherals. The EBI supports 8- or 16-bit devices and can use two 8-bit devices to emulate a single 16-bit device. The EBI implements the early read protocol, enabling faster memory accesses than standard memory interfaces. 5.2 Peripherals The AT91R40008 microcontrollers integrate several peripherals, that are classified as system or user peripherals. All on-chip peripherals are 32-bit accessible by the AMBA Bridge, and can be programmed with a minimum number of instructions. The peripheral register set consists of control, mode, data, status and enable/disable/status registers. An on-chip Peripheral Data Controller (PDC) transfers data between the on-chip USARTs and on- and off-chip memories address space without processor intervention. Most importantly, the PDC removes the processor interrupt handling overhead, making it possible to transfer up to 64K contiguous bytes without reprogramming the start address, thus increasing the performance of the microcontroller and reducing the power consumption. 5.2.1 System Peripherals The External Bus Interface (EBI) controls the external memory or peripheral devices via an 8or 16-bit data bus and is programmed through the Advanced Peripheral Bus (APB). Each chip select line has its own programming register. The Power-saving (PS) module implements the Idle mode (ARM7TDMI core clock stopped until the next interrupt) and enables the user to adapt the power consumption of the microcontroller to application requirements (independent peripheral clock control). The Advanced Interrupt Controller (AIC) controls the internal interrupt sources from the internal peripherals and the four external interrupt lines (including the FIQ) to provide an interrupt and/or fast interrupt request to the ARM7TDMI. It integrates an 8-level priority controller and, using the Auto-vectoring feature, reduces the interrupt latency time. The Parallel Input/Output Controller (PIO) controls up to 32 I/O lines. It enables the user to select specific pins for on-chip peripheral input/output functions and general-purpose 5 1732FS–ATARM–12-Apr-06 input/output signal pins. The PIO controller can be programmed to detect an interrupt on a signal change from each line. The Watchdog (WD) can be used to prevent system lock-up if the software becomes trapped in a deadlock. The Special Function (SF) module integrates the Chip ID, the Reset Status and the Protect registers. 5.2.2 User Peripherals Two independently configurable USARTs enable communication at a high baud rate in synchronous or asynchronous mode. The format includes start, stop and parity bits and up to 8 data bits. Each USART also features a Time-out and a Time-guard register, facilitating the use of the two dedicated Peripheral Data Controller (PDC) channels. The 3-channel, 16-bit Timer/Counter (TC) is highly programmable and supports capture or waveform modes. Each TC channel can be programmed to measure or generate different kinds of waves, and can detect and control two input/output signals. The TC also has three external clock signals. 6 AT91R40008 1732FS–ATARM–12-Apr-06 AT91R40008 6.

Product Overview 7.1 Power Supply The AT91R40008 microcontroller has two types of power supply pins: • VDDCORE pins, which power the chip core (i.e., the ARM7TDMI, embedded memory and the peripherals). • VDDIO pins, which power the I/O lines. An independent I/O supply allows a flexible adaptation to external component signal levels. 7.2 Input/Output Considerations After the reset, the peripheral I/Os are initialized as inputs to provide the user with maximum flexibility. It is recommended that in any application phase, the inputs to the AT91R40008 microcontroller be held at valid logic levels to minimize the power consumption. 7.3 Master Clock The AT91R40008 microcontroller has a fully static design and works on the Master Clock (MCK) provided on the MCKI pin from an external source. The Master Clock is also provided as an output of the device on the pin MCKO, which is multiplexed through a general-purpose I/O line. While NRST is active, MCKO remains low. After the reset, the MCKO is valid and outputs an image of the MCK signal. The PIO controller must be programmed to use this pin as standard I/O line. 7.4 Reset Reset restores the default states of the user interface registers (defined in the user interface of each peripheral) and forces the ARM7TDMI to perform the next instruction fetch from address zero. Except for the program counter, the ARM7TDMI registers do not have defined reset states. 7.4.1 NRST Pin NRST is active low-level input. It is asserted asynchronously, but exit from reset is synchronized internally to the MCK. The signal presented on MCKI must be active within the specification for a minimum of 10 clock cycles up to the rising edge of NRST to ensure correct operation. The first processor fetch occurs 80 clock cycles after the rising edge of NRST. 7.4.2 Watchdog Reset The Watchdog can be programmed to generate an internal reset. In this case, the reset has the same effect as the NRST pin assertion, but the pins BMS and NTRI are not sampled. Boot Mode and Tri-state Mode are not updated. If the NRST pin is asserted and the Watchdog triggers the internal reset, the NRST pin has priority. 7.5 7.5.1 Emulation Functions Tri-state Mode The AT91R40008 microcontroller provides a tri-state mode, which is used for debug purposes. This enables the connection of an emulator probe to an application board without having to desolder the device from the target board. In tri-state mode, all the output pin drivers of the AT91R40008 microcontroller are disabled. 8 AT91R40008 1732FS–ATARM–12-Apr-06 AT91R40008 To enter tri-state mode, the NTRI pin must be held low during the last 10 clock cycles before the rising edge of NRST. For normal operation, the NTRI pin must be held high during reset by a resistor of up to 400 kΩ. NTRI is multiplexed with I/O line P21 and USART1 serial data transmit line TXD1. Standard RS-232 drivers generally contain internal 400 kΩ pull-up resistors. If TXD1 is connected to a device not including this pull-up, the user must make sure that a high level is tied on NTRI while NRST is asserted. 7.5.2 JTAG/ICE Debug ARM standard embedded in-circuit emulation is supported via the JTAG/ICE port. The pins TDI, TDO, TCK and TMS are dedicated to this debug function and can be connected to a host computer via the external ICE interface. In ICE Debug mode, the ARM7TDMI core responds with a non-JTAG chip ID that identifies the microcontroller. This is not fully IEEE1149.1 compliant. 7.6 Memory Controller The ARM7TDMI processor address space is 4G bytes. The memory controller decodes the internal 32-bit address bus and defines three address spaces: • Internal memories in the four lowest megabytes • Middle space reserved for the external devices (memory or peripherals) controlled by the EBI • Internal peripherals in the four highest megabytes In any of these address spaces, the ARM7TDMI operates in Little-endian mode only. 7.6.1 Internal Memories The AT91R40008 microcontroller integrates 256K bytes of internal SRAM. All internal memories are 32 bits wide and single-clock cycle accessible. Byte (8-bit), half-word (16-bit) or word (32-bit) accesses are supported and are executed within one cycle. Fetching Thumb or ARM instructions is supported and internal memory can store twice as many Thumb instructions as ARM ones. The SRAM is mapped at address 0x0 (after the Remap command), allowing ARM7TDMI exception vectors between 0x0 and 0x20 to be modified by the software. Placing the SRAM on-chip and using the 32-bit data bus bandwidth maximizes the microcontroller performance and minimizes the system power consumption. The 32-bit bus increases the effectiveness of the use of the ARM instruction set and the ability of processing data that is wider than 16-bit, thus making optimal use of the ARM7TDMI advanced performance. Being able to dynamically update application software in the 256-Kbyte SRAM adds an extra dimension to the AT91R40008. 7.6.2 Boot Mode Select The ARM reset vector is at address 0x0. After the NRST line is released, the ARM7TDMI executes the instruction stored at this address. This means that this address must be mapped in nonvolatile memory after the reset. The input level on the BMS pin during the last 10 clock cycles before the rising edge of the NRST selects the type of boot memory (see Table 7-1). 9 1732FS–ATARM–12-Apr-06 The BMS pin is multiplexed with the I/O line P24, which can be programmed after reset like any standard PIO line. Table 7-1. BMS 1 0 Boot Mode Select Boot Memory External 8-bit memory on NCS0 External 16-bit memory on NCS0 7.6.3 Remap Command The ARM vectors (Reset, Abort, Data Abort, Pre-fetch Abort, Undefined Instruction, Interrupt, Fast Interrupt) are mapped from address 0x0 to address 0x20. In order to allow these vectors to be redefined dynamically by the software, the AT91R40008 microcontroller uses a Remap command that enables switching between the boot memory and the internal primary SRAM bank addresses. The Remap command is accessible through the EBI User Interface by writing one in RCB of EBI_RCR (Remap Control Register). Performing a Remap command is mandatory if access to the other external devices (connected to chip-selects 1 to 7) is required. The Remap operation can only be changed back by an internal reset or an NRST assertion. Abort Control The abort signal providing a Data Abort or a Pre-fetch Abort exception to the ARM7TDMI is asserted when accessing an undefined address in the EBI address space. No abort is generated when reading the internal memory or by accessing the internal peripherals, whether or not the address is defined. 7.6.4 7.6.5 External Bus Interface The External Bus Interface handles the accesses between addresses 0x0040 0000 and 0xFFC0 0000. It generates the signals that control access to the external devices, and can be configured from eight 1M byte banks up to four 16M bytes banks. It supports byte-, half-wordand word-aligned accesses. For each of these banks, the user can program: • Number of wait states • Number of data float times (wait time after the access is finished to prevent any bus contention in case the device is too long in releasing the bus) • Data bus width (8-bit or 16-bit) The user can program the EBI to control one 16-bit device (Byte Select Access mode) with a 16-bit wide data bus or two 8-bit devices in parallel that emulate a 16-bit memory (Byte Write Access mode). The External Bus Interface also features the Early Read Protocol, configurable for all the devices, which significantly reduces access time requirements on an external device in the case of single-clock cycle access. 10 AT91R40008 1732FS–ATARM–12-Apr-06 AT91R40008 8. Peripherals The AT91R40008 microcontroller peripherals are connected to the 32-bit wide Advanced Peripheral Bus. Peripheral registers are only word accessible – byte and half-word accesses are not supported. If a byte or a half-word access is attempted, the memory controller automatically masks the lowest address bits and generates a word access. Each peripheral has a 16-Kbyte address space allocated (the AIC only has a 4-Kbyte address space). 8.0.1 Peripheral Registers The following registers are common to all peripherals: • Control Register – write-only register that triggers a command when a one is written to the corresponding position at the appropriate address. Writing a zero has no effect. • Mode Register – read/write register that defines the configuration of the peripheral. Usually has a value of 0x0 after a reset. • Data Registers – read and/or write registers that enable the exchange of data between the processor and the peripheral. • Status Register – read-only register that returns the status of the peripheral. • Enable/Disable/Status Registers are shadow command registers. Writing a one in the Enable Register sets the corresponding bit in the Status Register. Writing a one in the Disable Register resets the corresponding bit and the result can be read in the Status Register. Writing a bit to zero has no effect. This register access method maximizes the efficiency of bit manipulation and enables modification of a register with a single noninterruptible instruction, replacing the costly read-modify-write operation. Unused bits in the peripheral registers are shown as “–” and must be written at 0 for upward compatibility. These bits read 0. 8.0.2 Peripheral Interrupt Control The Interrupt Control of each peripheral is controlled from the Status Register using the interrupt mask. The Status Register bits are ANDed to their corresponding interrupt mask bits and the result is then ORed to generate the Interrupt Source signal to the Advanced Interrupt Controller. The interrupt mask is read in the Interrupt Mask Register and is modified with the Interrupt Enable Register and the Interrupt Disable Register. The enable/disable/status (or mask) makes it possible to enable or disable peripheral interrupt sources with a non-interruptible single instruction. This eliminates the need for interrupt masking at the AIC or Core level in realtime and multi-tasking systems. 8.0.3 Peripheral Data Controller The AT91R40008 microcontroller has a 4-channel PDC dedicated to the two on-chip USARTs. One PDC channel is dedicated to the receiver and one to the transmitter of each USART. The user interface of a PDC channel is integrated in the memory space of each USART. It contains a 32-bit Address Pointer Register (RPR or TPR) in addition to a 16-bit Transfer Counter Register (RCR or TCR). When the programmed number of transfers are performed, a status bit indicating the end of transfer is set in the USART Status Register and an interrupt can be generated. 11 1732FS–ATARM–12-Apr-06 8.1 8.1.1 System Peripherals PS: Power-saving The Power-saving feature optimizes power consumption, enabling the software to stop the ARM7TDMI clock (Idle mode), restarting it when the module receives an interrupt (or reset). It also enables on-chip peripheral clocks to be enabled and disabled individually, matching power consumption and application need. AIC: Advanced Interrupt Controller The Advanced Interrupt Controller has an 8-level priority, individually maskable, vectored interrupt controller, and drives the NIRQ and NFIQ pins of the ARM7TDMI from: • The external fast interrupt line (FIQ) • The three external interrupt request lines (IRQ0 - IRQ2) • The interrupt signals from the on-chip peripherals The AIC is extensively programmable offering maximum flexibility, and its vectoring features reduce the real-time overhead in handling interrupts. The AIC also features a spurious vector, which reduces spurious interrupt handling to a minimum, and a protect mode that facilitates the debug capabilities. 8.1.2 8.1.3 PIO: Parallel I/O Controller The AT91R40008 microcontroller has 32 programmable I/O lines. Six pins are dedicated as general-purpose I/O pins. Other I/O lines are multiplexed with an external signal of a peripheral to optimize the use of available package pins. The PIO controller enables generation of an interrupt on input change on any of the PIO pins. WD: Watchdog The Watchdog is built around a 16-bit counter and is used to prevent system lock-up if the software becomes trapped in a deadlock. It can generate an internal reset or interrupt, or assert an active level on the dedicated pin NWDOVF. All programming registers are password-protected to prevent unintentional programming. 8.1.4 8.1.5 SF: Special Function The AT91R40008 microcontroller provides registers that implement the following special functions: • Chip identification • RESET status • Protect mode 12 AT91R40008 1732FS–ATARM–12-Apr-06 AT91R40008 8.2 8.2.1 User Peripherals USART: Universal Synchronous/ Asynchronous Receiver Transmitter The AT91R40008 microcontroller provides two identical, full-duplex, universal synchronous/asynchronous receiver/transmitters. Each USART has its own baud rate generator and two dedicated Peripheral Data Controller channels. The data format includes a start bit, up to 8 data bits, an optional programmable parity bit and up to 2 stop bits. The USART also features a Receiver Time-out Register, facilitating variable length frame support when it is working with the PDC, and a Time-guard Register, used when interfacing with slow remote equipment. 8.2.2 TC: Timer/Counter The AT91R40008 microcontroller features a Timer/Counter block that includes three identical 16-bit Timer/Counter channels. It is possible to independently program each channel to perform a wide range of functions, including frequency measurement, event counting, interval measurement, pulse generation, delay timing and pulse width modulation. The Timer/Counter can be used in Capture or Waveform mode, and all three counter channels can be started simultaneously and chained together. 13 1732FS–ATARM–12-Apr-06 9.
