User Interface
Peripheral Identifiers
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.

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.
