User Interface
Peripheral Identifiers
AT91SAM9261 Preliminary
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
Table 10-1
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.
