Section C - Interrupts (25 marks) 1. (10 marks) Assuming that the chip has just been reset, explain how to program the registers of the DACC so that an interrupt is generated after each digital to analog conversion has completed. The names, addresses and values for all relevant registers should be included and you should justify the values chosen for each field. Do not include any code in your answer. 2. (10 marks) In the programming language, write an initialization routine dacinit(), and interrupt handler daccirq() so that a continuous triangular wave (i.e. signal changes value every conversion and is either increasing to a maximum or decreasing to the minimum) appears on the DAC1 output. Your answer should not use any library calls or include files, must be clearly commented and use meaningful variable names. You can assume the other parts of the system, such as the NVIC, have been programmed appropriately. 3. (5 marks) Assuming a master clock frequency of 84 MHz, and a conversion period of 25 DACC Clock cycles, what is the expected frequency of the triangle wave output? Explain how you obtained your answer. Section C - Interrupts (25 marks) 1.
