Queries for stay of demand

Dear Experts

Can anyone clarifies that, Stay of Demand u/s 220(6), saves assessee from penalty u/s 221 for nonpayment of taxes, but would it also saves assessee from penal interest that AO may leavy for late payment of taxes. As demand itself get stayed, so there is no default for payment even appeal result against assessee and thereby assessee liable for payment of demand, then will assessee also saves from Penal Interest or else, Please clarify
