AT91SAM9G20 Summary

10. Peripherals

10.1

User Interface

The 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 19.

10.2 Identifiers

Table 10-1 defines the Peripheral Identifiers of the AT91SAM9G20. 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.
