10. Peripherals
10.1
User Interface
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 Figure 8-1 on page 18.
10.2
Peripheral Identifiers
The SAM7X512/256/128 embeds a wide range of peripherals. Table 10-1 defines the Peripheral
Identifiers of the SAM7X512/256/128. Unique peripheral identifiers are defined for both the
Advanced Interrupt Controller and the Power Management Controller.
