Normally user programs are prevented from handling $${\rm I}/O$$ directly by $${\rm I}/O$$ instructions in them. For $$CPUs$$ having explicit $${\rm I}/O$$ instructions, such $${\rm I}/O$$ protection is ensured by having the $${\rm I}/O$$ instructions privileged. In a $$CPU$$ with memory mapped $${\rm I}/O$$, there is no explicit $${\rm I}/O$$ instruction. Which one of the following is true for a $$CPU$$ with memory mapped $${\rm I}/O$$ ?
