📝 Programmed I/O Data Transfer in 8085 Microprocessor

Q1. A microcontroller stores N = 03h at address 2100h and the three bytes 12h, 34h, 56h at addresses 2101h‑2103h (least significant first). After executing the 8085 program, which value will be stored at address 2202h?

💡 Difficulty: easy | ✅ Correct: B

Q2. Given N = 02h stored at 2100h and bytes FFh and 01h at 2101h‑2102h (LSB first), what value will appear at 2201h after the program runs?

💡 Difficulty: medium | ✅ Correct: A

Q3. For N = 03h with bytes 00h, FFh, FFh at 2101h‑2103h (LSB first), what value will be stored at 2203h after execution?

💡 Difficulty: hard | ✅ Correct: A
