Hi to all, I used HSPLL instead of ECPLL to program some boards that it is too late to open them. HS is for crystal and EC is for external clock. HS works for both. Does any one know why HSPLL works for both and it is safe to use it. thanks Andre -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
