No you are correct but, you need 0xFD to make em all except PA1 outputs... I just assumed that writing a 1 made the whole port an output - then when the penny dropped I quickly dropped 0xFF into there - and started messing while the obviously resilient £35 pound chip slogged it out with the £13 eventual loser...
