Interrupt Servicing Priority in 8085 Microprocessor

Interrupt service requests in 8085 microprocessor are prioritized based on the type of interrupt being generated. In this case, the interrupts mentioned are RST 5.5, RST 6.5, and RST 7.5.

Interrupt Priority
- RST 5.5 has the highest priority among the interrupts mentioned.
- RST 6.5 has medium priority.
- RST 7.5 has the lowest priority.

Service Order
When multiple interrupts are received simultaneously, the 8085 microprocessor will service the interrupt with the highest priority first. Therefore, in this scenario, RST 7.5 will be serviced first, followed by RST 6.5, and then RST 5.5.

Conclusion
In conclusion, when all three interrupts (RST 5.5, RST 6.5, and RST 7.5) are generated simultaneously, the 8085 microprocessor will service the interrupts in the following order: RST 7.5, RST 6.5, and RST 5.5.
