Understanding the 8085 Microprocessor Registers
The 8085 microprocessor has a well-defined programming model that includes several important registers. Each register serves a specific purpose in the execution of instructions.
Registers Included in the Programming Model
- Instruction Register: Holds the current instruction being executed.
- Memory Address Register (MAR): Stores the address of the memory location to be accessed.
- Temporary Data Register (TDR): Used for temporary storage of data during instruction execution.
What is the Status Register?
The Status Register is sometimes referred to in context but is not part of the direct programming model of the 8085. Instead, it typically contains flags that indicate the status of the processor (like zero, carry, sign, parity, and auxiliary carry flags) after an operation has been performed.
Why Option 'C' is Correct?
- The Status Register is not explicitly used for programming purposes; it's more of an internal mechanism that reflects the state of the processor after operations.
- The other options (Instruction Register, Memory Address Register, Temporary Data Register) are integral to the flow of instructions and directly interact with the programming model.
Conclusion
In summary, while the Status Register provides essential information about the processor's state, it does not play a direct role in the programming model of the 8085 microprocessor, making option 'C' the correct answer. Understanding these distinctions helps clarify the roles of various registers in microprocessor design and functionality.
