SAM7X Series [SUMMARY DATASHEET]
6120IS–ATARM–14-Nov-13
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.
Note: 1. Setting SYSC and ADC bits in the clock set/clear registers of the PMC has no effect. The System Controller
and ADC are continuously clocked.
