Write a sequence of instructions to configure PQ2 pin (the SW0 button on the lab kit) as a source of INT0. Configure PQ0 to interrupt on the falling edge. Place INT0 interrupt on high priority. Enable interrupt globall

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.
