First thing we have to do is to specify the
general project information. This is done
by selecting the target microcontroller,
it’s operating clock frequency, and of
course - naming our project. This is an
important step, because the compiler
will adjust the internal settings based on
this information. Default conguration is
already suggested to us at the begining.
We will not change the microcontroller,
and we will leave the default AT89S8253
as the choice for this project.
