Q1. a) Let us assume that the CS and IP values of the base and offset of an ISR are 1230h and 2000h. The ISR is 10 lines of code where each line takes 4 bits to be stored. At which address, shall we find the IRET instruction? b) Describe the complete process of how an interrupt of type n (INTn) is serviced.
