Answer Posted / ragupathi
The interrupt table holds the vector address for each
vector interrupts. This is the starting address of the
subprogram .
On the occurance of particular interrupt,
microprocessor stops the execution of current instruction
and pushes the address of the next instruction into the
stack. And the PC(program counter) willbe transfered to
the vector address corresponding to that interrupt.Then it
start executing the subprogram.After completing the
execution of subprogram, the PC will be transferred to the
main program.
