Hello Micocali,

M>WY WITH 12F629 THE COMPILER SEND MOST ERROR AND WITH 12F675 NO ERROR?<<

As Melanie said before, the 12F675 is completely different that the 12F629.

the 629 doesn't use ADCON1

Each chip is different...just because they show two or three different chips for one data sheet, does not mean they are "compatible". It means the basics of the layout is the same, and one may have different amounds of RAM, ROM, and other charactoristics.
