Code to interrupt to ISR connect Hardware

Question

Write a code to interrupt to ISR connect Hardware and describe?

Answer 1

In Keil

void serial_ISR() interrupt 4 using 0

{

}

& in AVR studior

SIGNAL(Inteerupt_no)

{

}

hardware normally interrupt redirects the uC to predefined  addresses. In the case of high end processors the interrupt table will decide the interrupt vector address and whenever interrupt pin goes low, the table is searched for type & source of interrupt.
