Configuration Registers

Configuration registers are used to inform applications and operating systems about the setup

and configuration of the processor on which it is running. Some of the fields in the configuration

registers are fixed for all implementations using the AVR32 AP platform, while others, like the

number of sets in each cache, can be different for each implementation of the platform. Such

fields have IMPL in the Value field in the following tables. The programmer should refer to the

data sheet for the specific product in order to obtain information on IMPL fields. The AVR32

implements the following read-only configuration registers.
