User Interface
Peripheral Identifiers
The User Peripherals are mapped in the 256 Mbytes of address space between 0xF000 0000
and 0xFFFF EFFF. Each peripheral is allocated 16 Kbytes of address space.
A complete memory map is provided in
The AT91SAM7X512/256/128 embeds a wide range of peripherals.
Peripheral Identifiers of the AT91SAM7X512/256/128. Unique peripheral identifiers are defined
