  1. Memory Addressing Techniques

  2. Immediate Addressing • involves storing data in pairs with immediate values • register pairs:

  3. Immediate Addressing ~ Examples #1 ~ load the B register with 12 and the C register with 34

  4. Immediate Addressing ~ Examples #2 ~ load the D register with 54 and the E register with 32

  5. Immediate Addressing ~ Examples #3 ~ load the H register with 45 and the L register with 67

  6. Direct Addressing • assigns the contents of a memory location to a register • what we have seen so far

  7. Direct Addressing ~ Examples #1 ~ load the accumulator with the contents of address 1234

  8. Direct Addressing ~ Examples #2 ~ store the contents of the accumulator at address ABCD

  9. Indirect Addressing • involves loading and storing information in the accumulator • information in the accumulator is received from register pairs

  10. Indirect Addressing ~ Examples #1 ~ store the contents of registers B and C in the accumulator

  11. Indirect Addressing ~ Examples #2 ~ load the accumulator with FF and store the contents of the accumulator at memory location 2040
