AT91SAM7L128/64 Preliminary
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
The AT91SAM7L128/64 embeds a wide range of peripherals.
Identifiers of the AT91SAM7L128/64. Unique peripheral identifiers are defined for both the
Advanced Interrupt Controller and the Power Management Controller.

1. Setting SYSIRQ and ADC bits in the clock set/clear registers of the PMC has no effect. The
System Controller and ADC are continuously clocked. The ADC clock is automatically started
for the first conversion. In Sleep Mode the ADC clock is automatically stopped after each
conversion.
