The source operand is logically EXCLUSIVE ORed with the destination operand and the
result stored in the destination. The EXCLUSIVE OR operation results in a one bit
being stored whenever the corresponding bits in the operands are different;
otherwise, a 0 bit is stored.
c: Unaffected
Z:
Set if the result is zero; cleared otherwise
V: Always reset to 0
S: Set if the result bit 7 is set; cleared otherwise
H: Unaffected
0: Unaffected
If the source operand is the immediate value %78 (011111011) and the register named
TARGET contains %C3 (11000011), the statement
OR TARGET, 11%7B
leaves the value %BB (10111000) in the register.
When used to specify a 4-bit working-register address, address modes R or IR use the
format:
E
src/dst
