Instruction Overview

^ (Exclusive-OR)

General Form
dest_reg = src_reg_0 ^ src_reg_1
Syntax
Dreg = Dreg ^ Dreg ;
Syntax Terminology
:
Dreg R7–0
Instruction Length
In the syntax, comment (a) identifies 16-bit instruction length.
Functional Description
The Exclusive-OR (XOR) instruction performs a 32-bit, bit-wise logical
exclusive OR operation on the two source registers and loads the results
into the
dest_reg
The XOR instruction does not implicitly modify source registers. The
and one
dest_reg
itly modifies the
Flags Affected
The XOR instruction affects flags as follows.
• is set if the final result is zero, cleared if nonzero.
AZ
• is set if the result is negative, cleared if non-negative.
