In order to talk with an IC i need to pull up and pull down pins(it doesnt metter which and why)
It is even very easy to declare its routine inorder to start talking to it.
I have to ive some typical delayes between the pins timing according to the IC data sheet.
The problem is that ianm doing very thing right but when i am tring to see how it is working ......well it doesnt work altough i gave it a longer delayes then the typical suggestions of the manufactores.
But if i will go using the stepping (F10 on the AVR studio) and i am using ICE200 connected to the STK500 with the AT90S8515 ....It does work..
How can it be that when i am using the Step mode it works fine and when i am tring to simulate the system with out any break points and stepping it dorsnt work????
