Your Airbus is able to perform AUTOLAND on CATl runways, as long as your FMA shows at least CAT2 capability.
The aircraft will perform an autoland as long at least one autopilot is engaged and either CAT1, 2 or 3 along with G/S and LOC are annunciated on the FMA.
The limitation for autopilot engagement without at least CAT2 displayed is not below 160ft but the autopilot will remain engaged and go on to perform an autoland with only CAT1 displayed. Worth bearing in mind if your back was really against the wall.
