Operands
AX
Accumulator high (AH) or accumulator low (AL) register
loc16
Addressing mode (see Chapter 5)
Description
Perform a bitwise exclusive OR operation on the specified AX register (AH or
AL) and the contents of the location pointed to by the “loc16” addressing
mode. The result is stored in the specified AX register:
AX = AX XOR [loc16];
Flags and
Modes
N
The load to AX is tested for a negative condition. If bit 15 of AX is 1, then the
negative flag bit is set; otherwise it is cleared.
Z
The load to AX is tested for a zero condition. The zero flag bit is set if the
operation generates AX = 0, otherwise it is cleared.
Repeat
This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
Example
; XOR the contents of VarA and VarB and store in VarC:
MOV AL,@VarA
; Load AL with contents of VarA
XOR AL,@VarB
; XOR AL with contents of VarB
MOV @VarC,AL
; Store result in VarC
