Description:
Test the optional condition and if true, then perform the
specified bitwise logical operation (logical AND, inclusive OR, or exclusive
OR). If the condition is not true then perform a no-operation. Omitting the
condition performs the logical operation unconditionally. The operands are
contained in the data registers or constant specified in the instruction.
