SAM9G20

9. Peripherals

9.1 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 7-1.

9.2 Peripheral Identifiers

Table 9-1 defines the Peripheral Identifiers of the SAM9G20. 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.
