      An Introduction to Motorola’s 68HC05 Family of 8-Bit Microcontrollers Microcontrollers

      The Tutorial starts with an architectural overview of the 68HC05 central processor unit (CPU). It covers memory organization, the CPU programmer’s model, stack pointer operation, and the 68HC05 instruction set and its addressing modes. Once learned, this knowledge is applicable to all 68HC05 devices, because they all use the same CPU.

Mark Twain quote for the day:

The joy of killing! the joy of seeing killing done - these are traits of the human race at large. We white people are merely modified Thugs; Thugs fretting under the restraints of a not very thick skin of civilization; Thugs who long ago enjoyed the slaughter of the Roman arena, and later the burning of doubtful Christians by authentic Christians in the public squares, and who now, with the Thugs of Spain and Nimes, flock to enjoy the blood and misery of the bull-ring. We have no tourists of either sex or any religion who are able to resist the delights of the bull-ring when opportunity offers; and we are gentle Thugs in the hunting-season, and love to chase a tame rabbit and kill it. Still, we have made some progress - microscopic, and in truth scarcely worth mentioning, and certainly nothing to be proud of - still it is progress: we no longer take pleasure in slaughtering or burning helpless men. We have reached a little altitude where we may look down upon the Indian Thugs with a complacent shudder; and we may even hope for a day, many centuries hence, when our posterity will look down upon us in the same way.
