📝 Interrupt Instructions in 8085 Microprocessor

Q1. At which memory address does the 8085 automatically jump when the RST 7.5 interrupt is taken?

💡 Difficulty: easy | ✅ Correct: B

Q2. A system must invert a byte received from port 00H, then add 1 to obtain its 2’s complement before storing it at address 2200H. Which sequence of 8085 instructions correctly implements this operation?

💡 Difficulty: medium | ✅ Correct: B

Q3. Given N = 03H, initial data bytes 0xA5, 0x3C, 0xFF at addresses 2101H‑2103H, compute the resulting bytes stored at 2201H‑2203H after the provided 2’s complement program runs. Which of the following byte sequences is correct?
