XOR LOGICAL EXCLUSIVE-OR WORDS. XORs
the source word operand with the destination
word operand and stores the result in the
destination operand. The result has ones in
the bit positions in which either operand (but
not both) had a "1" and zeros in all other bit
positions.

XORB LOGICAL EXCLUSIVE-OR BYTES. XORs
the source byte operand with the destination
byte operand and stores the result in the
destination operand. The result has ones in
the bit positions in which either operand (but
