Thank you very much! The example is helpful. (But the documentation isn't :-(
This looks sufficient to implement the marking of separate bits.
Am I safe to assume that V bit value '0' will always mean 'defined' and
'1' will mean 'undefined'? Or at least that this meaning will not be
different for different address ranges?
I cannot find this mentioned in manual...
