Peripherals
10.1 User Interface
The User Peripherals are mapped in the 256 MBytes of address space between 0xF000 0000 and 0xFFFF EFFF. Each
peripheral is allocated 16 Kbytes of address space.
A complete memory map is provided in Figure 8-1 on page 20.
10.2 Peripheral Identifiers
The SAM7S Series embeds a wide range of peripherals. Table 10-1 defines the Peripheral Identifiers of the
SAM7S512/256/128/64/321/161. Table 10-2 defines the Peripheral Identifiers of the SAM7S32/16. 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.
Note:
1. Setting SYSC and ADC bits in the clock set/clear registers of the PMC has no effect. The System Controller
is continuously clocked. The ADC clock is automatically started for the first conversion. In Sleep Mode the
ADC clock is automatically stopped after each conversion.
