9. Peripherals

9.1 User Interface

The User Peripherals are mapped in the upper 256 Mbytes of the address space between the addresses 0xFFFA

0000 and 0xFFFC FFFF. Each User Peripheral is allocated 16 Kbytes of address space.

A complete memory map is presented in Figure 7-1 on page 17.

9.2 Peripheral Identifiers

Table 9-1 defines the Peripheral Identifiers of the SAM9261. 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.

Note: Setting AIC, SYSC, UHP, LCDC and IRQ0 to IRQ2 bits in the clock set/clear registers of the PMC has no effect.
