Question 1 (20 points) How does an interrupt service routine differ from a standard function in C You cannot pass or return data when it is called It does not return to the original code execution point unlike a standard function It cannot be called multiple times unlike a standard function It has a much more limited size than a standard C function Question 2 (20 points) Which of the following is NOT an advantage of interrupts over polling for event detection? More efficient in terms of instruction cycles Reduces code complexity Increases code security Easier handling of intermittent (asynchronous) events Question 3 (20 points) Which of the following is NOT one of the 3 interrupts controlled via the INTCON register Timer O overflow interrupt PORTB(7:4) level change interrupt RBO external interrupt ADC conversion complete interrupt
