Question 4 (20 marks) (a) A Timer 2 block diagram is shown in Fig.7. Timer 2 is used to generate a delay of 50 us. Determine the value of the PR2 if the TMR2 is 0, the prescaler and the postscaler of 1:1 are selected. Assume that the crystal clock is running at the frequency of 20 MHz. Ignore the overhead due to instructions in the calculation. [6 marks] (ii) Explain how the microcontroller knows the delay of 50 us...

A. Design a circuit using D flip-flops that will generate the
sequence 0, 0, 1, 0, 1, 1 and repeat. Do this by designing a
counter for any sequence of states such that the first flip-flop
takes on this sequence. There are many correct answers, but do not
duplicate states, because each state can have only one next
state.

(20 points) Using any state encodings you want, generate a state table for the following state diagram. Note that there is one input, X, and there are two outputs, Y and Z. You can come up with whatever names you want for your state variables. And then generate the logic equations for the next state signals (assume D flip-flops for maintaining state) and the output signals, Y and Z 7. A0 A/Y 070 x=1 x=1 x =1 x =0 x...
