If the execution condition is ON, the instructions between IF(802) and
ELSE(803) will be executed and if the execution condition is OFF, the
instructions between ELSE(803) and IEND(804) will be executed.

If the operand bit is ON, the instructions between IF(802) and ELSE(803) will
be executed. If the operand bit is OFF, the instructions between ELSE(803)
and IEND(804) will be executed.
