SAM7S Series Summary
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.

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 Manage-
ment Controller.

1. Setting SYSC and ADC bits in the clock set/clear registers of the PMC has no effect. The Sys-
tem 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.
