-/**
- Called at the early stage of the Boot phase to know if the memory has already been initialized
-
- Running the code from the reset vector does not mean we start from cold boot. In some case, we
- can go through this code with the memory already initialized.
- Because this function is called at the early stage, the implementation must not use the stack.
- Its implementation must probably done in assembly to ensure this requirement.
-
- @return Return the condition value into the 'Z' flag
