... User Peripherals AT91R40008 - Summary 6 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 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. ...

... Associated Documentation The AT91R40008 is part of the AT91X40 series of microcontrollers, a member of the Atmel AT91 16/32-bit microcontroller family, which is based on the ARM7TDMI processor core. The table below contains details of associated documentation for further reference. Table 2. Associated Documentation Product Information Internal architecture of processor ARM/Thumb instruction sets ...

... AT91R40008 microcontroller be held at valid logic levels to minimize the power consumption. 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 ...

... Internal peripherals in the four highest megabytes In any of these address spaces, the ARM7TDMI operates in Little-endian mode only. 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 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 mem- ory and the internal primary SRAM bank addresses ...

... The AIC also features a spurious vector, which reduces spurious interrupt handling to a minimum, and a protect mode that facilitates the debug capabilities. The AT91R40008 microcontroller has 32 programmable I/O lines. Six pins are dedi- cated 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 ...
