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

SBB

By
Syntax: SBB 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. A= A- R-b 3.  4. Flag Example: SBB D where  [D] = 10H , [A]= 22H and [c flag]= 1 After execution of SBB  B [A] = 11H  [D] = 10H // A= A-R-b => 22-10-1 =11H Program: write an ALP for subtraction of values present in Registers A ,B and C. Where A carries 44H and B carries 30H and C carries 10H. Store result at memory location 5000H. Label  Mnemonics  Comments Start: SUB B ;  a=a - b// 44-30= 14h            SBB  C ;  a= a - c - cy... A= 14-10-0 = 4h           STA 5000H   Stop: HLT Output: [5000H]= 04H
