Question: What is a multiplexed bus? Is the HC11s expanded memory bus multiplexed? If so, how? Locate the crystal on the board. What can you infer

  1. What is a multiplexed bus? Is the HC11s expanded memory bus multiplexed? If so, how?
  2. Locate the crystal on the board. What can you infer about its frequency of oscillation? (68HC11)
  3. Write a program to print out an 8-bit unsigned binary number stored in a memory location. If the number is $4C or binary 01001100, the program should print out 01001100. Please use THRSim11.
  4. Write a program to print out an 8-bit unsigned binary number stored in a memory location as a string. For example, if a value $B1 (177 decimal) is stored in a memory location, your program should print out 177. Please use THRSim11.
