4-BIT MCU FOR REMOTE CONTROLLER(MASK TYPE)

Silan Microelectronics 

10. INC B

11. DEC D

12. DEC H

13. DEC B

14. INC LL

15. INC LH

16. DEC LL

17. DEC LH

18. AND A, @LL

19. OR A, @LL

20. XOR A,@LL

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

SF, SF=/CF.

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

SF, SF=CF.

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

SF, SF=CF.

Decrement instruction. Decrement the contents of the B register by 1. This will affect

SF, SF=CF.

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

SF, SF=/CF.

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

SF, SF=/CF.

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

Subtract 1 from the content in register LH. SF is affected, SF=/CF.

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

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

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

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

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

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

c. TEST @LL, b

Clear the B-bit of the RAM pointed at by the LL register.

Set the B-bit of the RAM pointed at by the LL register to be 1.

Test the B-bit of the RAM pointed at by the LL register. If this bit is1, the SF is set to

0; otherwise, the SF is set to 1.
