... 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 dif- ferent kinds of waves, and can detect and control two input/output signals. The TC has also three external clock signals.

... ARM7TDMI advanced performance. Being able to dynamically update application software in the 128-Kbyte SRAM adds an extra dimension to the AT91R40807. This 128-Kbyte SRAM can also be used to vali- date the code to be stored in the on-chip ROM memory prior to mass production of the AT91M40807. At system boot, the code is downloaded from external nonvolatile mem- ory to this on-chip extended SRAM ...

... The ARM vectors (Reset, Abort, Data Abort, Prefetch 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 AT91R40807 Microcontrollers use a remap command that enables switching between the boot mem- ory and the internal primary SRAM bank addresses ...

... PIO: Parallel I/O Controller The AT91R40807 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 and insertion of a simple input glitch filter on any of the PIO pins ...

... PDC, and a Time Guard register, used when interfac- ing with slow remote equipment. The AT91R40807 microcontroller features a Timer Counter block that includes three identical 16-bit timer counter channels. Each channel can be independently pro- grammed to perform a wide range of functions including frequency measurement, event counting, interval measurement, pulse generation, delay timing and pulse width modulation ...
