Detailed Description

The CPU register test checks the functionality of the CPUs registers.

POST and BIST tests are available. The register test is realized in assembler
language to ensure direct access to all register. This tests are compiler coded specific according to their mnemonics.
Selecting the correct assembler source is necessary for compilation.
