8. Peripherals
8.1 Peripheral Mapping
As shown in Figure 6-1, the Peripherals are mapped in the upper 256 Mbytes of the address space between the
addresses 0xF000_0000 and 0xFFFF_C000.
Each User Peripheral is allocated 16 Kbytes of address space.
8.2 Peripheral Identifiers
Table 8-1 defines the Peripheral Identifiers of the SAM9G25. A peripheral identifier is required for the control of the
peripheral interrupt with the Advanced Interrupt Controller and for the control of the peripheral clock with the Power
Management Controller.
