SUI

By




Syntax: SUI 8-bit
Where 8-bit is an immediate data operand. 
Byte: 2byte
Addressing Mode: Immediate Addressing

Working: 
1. 
2. 
3. 
4. Flag

Example: SUI 11H
where  [A]= 22H
After execution of SUI 11H
[A] = 11H 


Program: write an ALP for 8bit subtraction of value present in Register A that is 44H with an immediate value 30H. Store result at memory location 5000H.

Label  Mnemonics  Comments
Start: SUI 30H
          STA 5000H 
 Stop: HLT

Output: [5000H]= 14H

STAX

By
Syntax: STAX Rhp Where  Rhp is higher order register  the pair. (HL, BC or DE) Byte: 1byte Addressing Mode: Register Indirect Addressing Working:  for execution of this instruction, microprocessor will allocate first byte for opcode and the operand is register which don't need allocation. Example: STAX H where [L]= FFH [H] = 40 H [A]= 88H After execution of STAX H [40FF H]= 88 H

SBI

By
Syntax: SBI 8bit  Where 8-bit is an immediate data operand.  Byte: 2byte Addressing Mode: Immediate   Addressing Working:  1.  2. A= A- 8bit -b 3.  4. Flag Example: SBI 10H where  [A]= 22H and [c flag]= 1 After execution of SBI   10H [A] = 11H  // A= A-8bit-b => 22-10-1 =11H Program: write an ALP for subtraction of 30H value from Registers A  Where A carries 44H and Cy flag carries borrow value 1. Store result at memory location 5000H. Label  Mnemonics  Comments Start:   SBI 30H        ;  a= a-8bit- cy...                                    ; A= 44- 30 -1 = 13h             STA 5000H   Stop: HLT Output: [5000H]= 13H

SUB

By
Syntax: SUB R Where R can be any of the general purpose registers (A,B,C,D,E,H andL) Byte: 1byte Addressing Mode: Register   Addressing Working:  1.  2.  3.  4. Flag Example: SUB B   where  [B] = 11H  and [A]= 22H After execution of  SUB  B [A] = 11H  [B] = 22H Program: write an ALP for 8bit subtraction  of values present in Registers A and B where A carries 44H and B carries 30H. Store result at memory location 5000H. Label  Mnemonics  Comments Start: SUB B            STA 5000H   Stop: HLT Output: [5000H]= 14H LXI H, 4000H ;  4000= 90h MOV A,M ; a = 90h INX H ;  4001h where 4001= 40h MOV B, M ; b= 4 0h SUB B ; a = a - b ... A = 90 - 40= 50h INX H ;  4002h MOV M,A ;  4002h = 50h HLT
