No Digital Oscilloscope changes on proteus

[himam]

I can't get any changes on digital oscillation changes on my atmega8515.
Here is my assembly code,

Hello!

When asking something, you may consider saying hello, please, thank you, etc...
Beside this, you could also explain what exactly you want to do.
You say:

I can't get any changes on digital oscillation changes on my atmega8515.

Getting changes on the changes, is not obvious to me. Do you mean you can't write
to the output ports?
Next, the code you post looks like this:

I understand START, STOP, SW0 / SW1, but that's about it. So another good practice if you
post to mostly english forum is to comment your code in english.

So explain first, if possible politely, and you might "get" more answers.

Dora.
