1. ADD A, @LL

Add the contents of RAM pointed at by the LL to accumulator, store the sum in the

ACC. This operation will affect SF, SF=/CF.

2. ADDC A, @LL

Add the contents of RAM pointed at by the LL register to accumulator with carry.

Store the carry bit in the CF. This operation will affect SF, SF=/CF.

3. ADD A,#K

Add immediate K to accumulator. Store the sum in the ACC. This will affect SF,

SF=/CF.

4. ADD L,#K

Add immediate K to the LL register. Store the sum in the LL. This will affect SF,

SF=/CF.

Subtract instruction with borrow(the complement of carry). Subtract the contents of

the accumulator from the contents of RAM pointed at by the LL register, subtract the

5. SUBRC A, @LL

complement of the carry bit, then store the results in the accumulator, transfer the

carry bit to the CF, this will affect SF and CF, SF=CF.

6. INC @LL

Increment instruction. Increment the contents of RAM pointed at by the LL register

by 1. This will affect SF, SF=/CF.

7. DEC @LL

Decrement instruction. Decrement the contents of RAM pointed at by the LL register

by 1. This will affect SF, SF=CF.

8. INC D

Increment instruction. Increment the contents of the D register by 1. This will affect

SF, SF=/CF.

9. INC H

Increment instruction. Increment the contents of the H register by 1. This will affect

SF, SF=/CF.
