Hello to all, I have just started a project using a Pic16F628 and I would like to use the external resistor oscillator. On page 98, section 14.2.5 of the data sheet it covers this option, but refers to the Electrical Spec. section for the resistor size. I have reviewed this section but I can't find this information. Am I just missing the obvious or is there something missing from the data sheet? Any help would be greatly appreciated. Rod -- http://www.piclist.com#nomail Going offline?
