No disrespect to Petzold intended (I'm a huge fan of his technical works) but "Code" is at best at a pop-sci level. It prepares one for doing digital logic as well as "A Brief History Of Time" prepares one for doing coursework in cosmology. Try the Brown book or Mano's "Digital Design" (my preference; took a while to remember his name) and see if it works for you. Good luck.
