03.

ADD A, #k

Add immediate K to accumulator. And store the sum in the ACC. This will

affect SF, SF=/C.

04.

ADD LL, #k

Add immediate K to the LL register and store the sum in the LL. This will

affect SF, SF=/C.

05.

SUBRC A, @LL

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

contents of the accumulator from the contents of RAM pointed at by the LL

accumulator, transfer the carry bit to the CF, this will affect SF and CF,

SF=C.

06.

INC @LL

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

07.

DEC @LL

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

08.

INC LL

Increment instruction. Increment the contents of the LL register by 1. This

will affect SF, SF=/C.

DEC LL

Subtract 1 from the content in register LL. SF is affected, SF=C.

10.

INC D

Increment instruction. Increment the contents of the DC register by 1. This

will affect SF, SF=/C.

11.

INC H

Increment instruction. Increment the contents of the HR register by 1. This

will affect SF, SF=/C.

12.

INC B

Increment instruction. Increment the contents of the BR register by 1. This

will affect SF, SF=/C.

13.

DEC D

Decrement instruction. Decrement the contents of the DC register by 1. This

will affect SF, SF=C.

14.

DEC H

Decrement instruction. Decrement the contents of the HR register by 1. This

will affect SF, SF=C.

15.

DEC B

Decrement instruction. Decrement the contents of the BR register by 1. This

will affect SF, SF=C.

16.

AND A, @LL

The contents of the accumulator and RAM pointed at by the LL register are

ANDed and the results are stored in the accumulator. SF is changed, SF=/Z.

17.

OR A, @LL

The contents of the accumulator and RAM pointed at by the LL register are

ORed and the results are stored in the accumulator. SF is changed, SF=/Z.

18.

XOR A,@LL

The contents of the accumulator and RAM pointed at by the LL register are

XORed and the results are stored in the accumulator. SF is changed, SF=/Z.
