| Question 5 |
In a vectored interrupt
| The branch address is assigned to a fixed location in memory
| |
| The interrupting source supplies the branch information to the processor
| |
| The branch address is obtained from a register in the processor
| |
| None of the above |
Question 5 Explanation:
In a vectored interrupt, each interrupting device or source is assigned a specific vector address.
When an interrupt occurs, the interrupting device sends its vector address to the processor.
The processor uses this vector address to locate the corresponding interrupt service routine (ISR) or branch address.
This allows the processor to directly jump to the specific routine associated with the interrupting device
