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
