[En-Nut-Discussion] protecting memory from NutOS

if I look at the circuit diagrams of Ethernut 1 I do not see any adress
decoder. For me it seems that the RTL chip is adressed at the whole adress
space above $8000. Or ist ther an address decoder inside the RTL? So ist it
safe to use the free area or are there mirrors of the RTL?

Thank you
Thorsten
