AT91SAM9261 Preliminary
10. Peripherals
10.1
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 8-1 on page 16.
10.2
Peripheral Identifiers
Table 10-1 defines the Peripheral Identifiers of the AT91SAM9261. 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, SYSIRQ, UHP, LCDC and IRQ0 to IRQ2 bits in the clock set/clear registers of the
PMC has no effect.
