I can't find it anywhere on the web. Really?! It's an Atmel part, so the obvious place to start must, surely, be http://www.Atmel.com Once you're there, simply put "AT89S8253" into the 'Search' box and you will quickly get to the following page - which tells you everything you need to know about the AT89S8253: http://www.atmel.com/dyn/produ...rt_id=3449 In particular, the Datasheet is here: http://www.atmel.com/dyn/resou...oc3286.pdf And there's an "AT89S8253 Primer": http://www.atmel.com/dyn/resou...oc3655.pdf And a whole list of Software Examples! I've tried DDR1=0x... and PORTP1=...; PORT1=... but it doesn't work. Whatever made you think it would work? There is absolutely no mention whatsoever of anything called "DDR1" in the Datasheet! |
