isn't real RAM? or why can't it been accessed ?

They are Undefined; that is all that you can know about them - nothing more, nothing less.

Writing to or reading from these registers may produce undefined values orbehavior.

So just heed the warning - do not attempt to write to or read from any undefined SFR location.

Note that this also applies to undefined bits within an otherwise-defined SFR...
