Prob 1. ( 30 points, 10 points each) Consider the setup of a 16-bit timer that has a 16-bit prescaler. Assume the input clock to the timer has a clock with fCL.18sC=65.54MHz. Answer the following questions: 1. What is the lowest frequency of the output pulse (the interrupt) of the timer if the timer is set up to be edge-aligned up-coumting without the prescaler? 2. How can we choose the values of the PSC and the RR so that we can lave fCA,CNT=10 kHz and the output interrupt rate of the timer being 10Hz using the odge-aligned up-counting mode? 3. Suppose we inadvertently set up the mode to centered-aligned with the same values of the PSC and the ARR as before. What is the interrupt rate of the timer when we only use overflow
