What is the vectored address of RST-5?
Answer & step-by-step solution
In the 8085, restart instruction RST n vectors to address 8×n. Therefore RST 5 vectors to 5×8=40 decimal = 28H.
Concept & Reasoning
The 8085 reserves fixed restart locations separated by 8 bytes: RST0 at 0000H, RST1 at 0008H, …, RST5 at 0028H. This should not be confused with hardware interrupt vector addresses such as RST5.5, RST6.5 and RST7.5.
How to Solve It in the Exam
RST number × 8 → hexadecimal vector address.
Important Exam Point
Differentiate software RST 5 from hardware RST 5.5.
Quick Trick
RST number × 8 → hexadecimal vector address.
Common Mistake
Writing 0032H by treating decimal 40 as hexadecimal 40.
RST-5 का वेक्टर एड्रेस क्या है?
उत्तर और चरणबद्ध हल
C — 0028H। 8085 में RST n, 8×n एड्रेस पर वेक्टर करता है। अतः RST 5 → 5×8 = 40 दशमलव = 28H।

RST-5નું વેક્ટર એડ્રેસ શું છે?
જવાબ અને પગલાવાર ઉકેલ
C — 0028H. 8085માં RST n એ 8×n એડ્રેસ પર વેક્ટર કરે છે. તેથી RST 5 → 5×8 = 40 દશાંશ = 28H.
