If INTO and INT1 are enabled and EICRA=0x0D then ______ Select one: a. the rising edge of INTO and the falling edge of INT1 generates an interrupt request b. any logic change on INTO and the rising edge of INT1 generates an interrupt request c. the falling edge of INTO and the rising edge of INT1 generates an interrupt request d. the falling edge of INTO and any logic change on INT1 generates an interrupt request Clear my choice

(a) The SR flip-flop can be converted to a D flip-flop. Illustrate the conversion and block diagram using additional logic gates. (b) The D input and a single clock pulse are shown in Figure Q5b. Compare the resulting Q outputs for positive edge-triggered and negative edge-triggered. The flip-flops are initially RESET. (c) A 3-bit counter has the following counting sequence: 0, 1, 2, 5, 7, 6, 4, 3, 0... repeats. Determine the state transition diagram, MOD number of the counter, and number of states.

A new clocked X-Y flip flop is defined with two inputs, X and Y, in addition to the clock input. The flip flop functions as follows: If XY = 00, the flip flop state Q becomes 0 with the next clock pulse. If XY = 01, the flip flop state Q becomes 1 with the next clock pulse. If XY = 10, the flip flop changes state with each clock pulse. If XY = 11, the flip flop state Q becomes 1 with the next clock pulse. a) Write the truth table for the XY flip flop. b) Write the excitation table for the XY flip flop. c) It is desirable to convert an SR flip flop into an X-Y flip flop by adding some external gates if necessary. Draw a circuit to show how you will implement the XY flip flop using an SR flip flop.
If each flip flop has a clock-to-Q delay of 1 ns, how much time will it take for the output to change to its next state in the case of a 4-bit Ripple Counter?
