Your question is 8085 Microcontroller Architecture. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain the architecture of the 8085 microcontroller.
Describe the major internal blocks, address and data-bus operation, instruction execution, interrupt structure, serial I/O, and external memory or peripheral interfacing. Include relevant trust boundaries and explain how firmware integrity, unauthorized bus activity, and fault conditions could be detected or mitigated in a practical embedded design.
