Thanks Jumper I take the point. Now another daft question. In order to get my Christmas "Star of David" working I need three 8 bit ports and was planning to use the 44 pin demo board. Port A.6 and PortA.7 will not work as outputs presumable because they are connected to the crystal . Sinc I am using the internal oscillator can I do anything to make these two pins available as outputs. Incidentally maybe I am going blind but I can't see any reference to the osccal command in the manual.
Cheers
