10. User Peripherals
10.1
User Interface
The User Peripherals are mapped in the upper 256M bytes of the address space, between the
addresses 0xFFFA 0000 and 0xFFFE 3FFF. Each peripheral has a 16-Kbyte address space.
A complete memory map is presented in Figure 8-1 on page 17.
10.2
Peripheral Identifiers
The AT91RM9200 embeds a wide range of peripherals. Table 10-1 defines the peripheral iden-
tifiers of the AT91RM9200. 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.
