Peripherals
8.1
Peripheral Mapping
As shown in
, 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.
8.2
Peripheral Identifiers
defines the Peripheral Identifiers of the SAM9N12/CN11/CN12. 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.
