Asynchronicity (sp?) is not a problem in the 555 type of design. There
are no different data and clock lines, except if there is a reason to
call them so. Otherwise the data lines are usually just called Red and
White. The TI protocol doesn't use different data and clock lines (find
more about this yourself if you need to). In asm they can be (and
usually are) accessed individually. Check the link port documentation at
www.ticalc.org.
(Somehow I have a feeling that someone is reinventing the wheel
here...I've been experimenting with a 555 IR link for a long time and
it's almost finished...check www.clinet.fi/~ozone/irlink for more info)
