10. Peripherals
10.1
User Interface
The User Peripherals are mapped in the 256 MBytes of address space between 0xF000 0000
and 0xFFFE FFFF. Each peripheral is allocated 16 Kbytes of address space.
A complete memory map is provided in Figure 8-1 on page 19.
10.2
Peripheral Identifiers
The AT91SAM7XC512/256/128 embeds a wide range of peripherals. Table 10-1 defines the
Peripheral Identifiers of the AT91SAM7XC512/256/128. Unique peripheral identifiers are
defined for both the Advanced Interrupt Controller and the Power Management Controller.
Note:
1. Setting SYSC and ADC bits in the clock set/clear registers of the PMC has no effect. The Sys-
tem Controller and ADC are continuously clocked.
