Peripherals
8.1
Peripheral Mapping
As shown in Figure 6-1, the Peripherals are mapped in the upper 256M bytes of the address
space between the addresses 0xFFF7 8000 and 0xFFFC FFFF.
Each User Peripheral is allocated 16K bytes of address space.
8.2
Peripheral Identifiers
Table 8-1 defines the Peripheral Identifiers of the SAM9N12. 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.
