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 conguration 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.
