7. Peripherals
7.1 Peripheral Mapping
As shown in Figure 5-1 “SAM9G45 Memory Mapping”, the peripherals are mapped in the upper 256 Mbytes of the
address space between the addresses 0xFFF7 8000 and 0xFFFC FFFF.
Each User Peripheral is allocated 16 Kbytes of address space.
7.2 Peripheral Identifiers
Table 7-1 defines the Peripheral Identifiers of the SAM9G45. 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.
