VxWorks Interview Question:

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

Submitted by: Administrator

In Keil
void serial_ISR() interrupt 4 using 0
{
}

& in AVR studio
SIGNAL(Inteerupt_no)
{
}

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