Oops ,forgot to mention about Programmable interval timer
on http://www.intel.com/design/archives/periphrl/docs/23124406.pdf

That have 3 outs ( 40h , 41h , 42h ) each on can be prorgammed
independantly.

  • Re: Delay Routine: Fully-portable C89 if possible
    ... difference between a 33-Bit int and a 32-Bit int is that the former ... The speed difference will, of course, vary depending on the code in question, and the cpus in question - but some 32-bit cpus work twice as fast on 32-bit data as they do on smaller data, and 8-bit cpus clearly work much faster on the smaller data. ... it avoids multiplies on lookups - multiplies can be costly on small cpus. ... The compiler should pad the struct to ensure that accesses are possible, but not necessarily optimal - if you know the exact sizes, you can add padding yourself to choose a balance between space and speed. ...
