... The EBI implements the early read protocol, enabling faster memory accesses than standard memory interfaces. The AT91FR4081 embeds a Flash memory organized as 512K 16-bit words, accessed via the EBI. Its main function program memory. A 16-bit Thumb instruction can be loaded from Flash memory in a single access ...

... 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 has also 3 exter- nal clock signals. 1386C–ATARM–02/02 AT91FR4081 7 ...

... In any of these address spaces, the ARM7TDMI operates in Little-Endian mode only. Internal Memories The AT91FR4081 integrates 8K bytes of primary internal SRAM that is 32 bits wide and sin- gle-clock cycle accessible. This memory bank is mapped at address 0x0 (after the remap command), allowing ARM7TDMI exception vectors between 0x0 and 0x20 to be modified by the software ...

... In the event that the Flash Uploader is erased from the first sector while the new final applica- tion is not yet programmed, and while the target system power supply is switched off, it would lead to a non-recoverable error and the AT91FR4081 could not be re-programmed by using the Flash Uploader. ...

... This eliminates the need for interrupt masking at the AIC or Core level in real- time and multi-tasking systems. Peripheral Data The AT91FR4081 has a 4-channel PDC dedicated to the two on-chip USARTs. One PDC Controller channel is dedicated to the receiver and one to the transmitter of each USART. ...

... The AIC also features a spurious vector detection feature, which reduces spurious interrupt handling to a minimum, and a protect mode that facilitates the debug capabilities. PIO: Parallel I/O The AT91FR4081 has 32 programmable I/O lines. Six pins are dedicated as general-purpose Controller I/O pins. Other I/O lines are multiplexed with an external signal of a peripheral to optimize the use of available package pins ...

... PDC, and a Time-guard register, used when interfacing with slow remote equipment. TC: Timer Counter The AT91FR4081 features a Timer Counter block that includes three identical 16-bit timer counter channels. Each channel can be independently programmed to perform a wide range of functions including frequency measurement, event counting, interval measurement, pulse generation, delay timing and pulse width modulation ...
