AT91SAM7SE512/256/32 Preliminary Summary

10. Peripherals

10.1

User Interface

The User Peripherals are mapped in the 256 MBytes of the address space between

0xF000 0000 and 0xFFFF EFFF. Each peripheral is allocated 16 Kbytes of address space.

A complete memory map is presented in Figure 8-1 on page 22.

10.2

Peripheral Identifiers

The AT91SAM7SE512/256/32 embeds a wide range of peripherals. Table 10-1 defines the

Peripheral Identifiers of the AT91SAM7SE512/256/32. 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 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.
