2.4 From the Classroom Whiteboard/ChalkboardIndex

• Your in-class notes go here.

• What you might need is a Binary Watch - see image.

• bitwise operators: AND OR XOR NOT -> & | ^ ~
  • for any values a and b, explain what happens after the following two XOR operations (e.g. try a=5,b=10 and see what happens):
    • a = a^b
    • a = a^b
  • for any values a and b, explain what happens after the following three XOR operations (e.g. try a=5,b=10 and see what happens):
    • a = a^b
    • b = a^b
    • a = a^b
• The LMC (continued)
  • see the Class Notes, above
  • review: instruction cycle (remember the Increment!)
  • instructions that fail if the Increment is done third instead of second: JMP and CALL
  • how the JMP and SKZ instructions work with the Counter
  • use of labels instead of mailbox numbers in writing assembly language
    • see 350_LMC_sample3.txt - LMC Sample Program #3
