Description
Perform a bitwise XOR operation on the ACC register with the
zero-extended content of the location pointed to by the “loc16” address
mode. The result is stored in the ACC register:
ACC = ACC XOR 0:[loc16];
Flags and
Modes
N
The load to ACC is tested for a negative condition. If bit 31 of ACC is 1, then
the negative flag bit is set; otherwise it is cleared.
Z
The load to ACC is tested for a zero condition. The zero flag bit is set if the
operation generates ACC = 0; otherwise it is cleared
Repeat
This operation is repeatable. If the operation follows a RPT instruction,
then the XOR instruction will be executed N+1 times. The state of the Z
and N flags will reflect the final result.
Example
; Calculate the 32-bit value: VarA = VarA XOR 0:VarB
MOVL ACC,@VarA
; Load ACC with contents of VarA
XOR ACC,@VarB
; XOR ACC with contents of 0:VarB
MOVL @VarA,ACC
; Store result in VarA
