Memory Access
Access Classes
Access classes are used to specify how TRACE32 PowerView accesses memory, registers of
peripheral modules, addressable core resources, coprocessor registers and the
Addresses in TRACE32 PowerView consist of:
•
An access class, which consists of one or more letters/numbers followed by a colon (:)
•
A number that determines the actual address
Here are some examples:
Access Classes to Memory and Memory Mapped Resources
The following memory access classes are available:
In addition to the access classes, there are access class attributes.
