| Question 49 |
The 8085 microprocessor responds to the present of an interrupt
| as soon as the TRAP pin becomes ‘high’ | |
| by checking the TRAP pin for ‘high’ status at the end of each instruction each | |
| by checking the TRAP pin for ‘high’ status at the end of the execution of each instruction | |
| by checking the TRAP pin for ‘high’ status at regular intervals |
Question 49 Explanation:
TRAP is non maskable interrupt . TRAP is active high, level, edge triggered non maskable highest priority interrupt. When TRAP line is active microprocessor insert intervals restarts automatically at vector location of TRAP.
Correct Answer: C
