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 SAM9X25. A peripheral identifier is required
for the control of the peripheral interrupt with the Advanced Interrupt Controller and for the con-
trol of the peripheral clock with the Power Management Controller.
