1. The INV instruction operates based on the results of calculation made until the INV instruction is given. Accordingly, use it
in the same position as that of the AND instruction.
The INV instruction cannot be used at the LD and OR positions.
2. When a ladder block is used, the operation result is inverted within the range of the ladder block. To operate a ladder using
the INV instruction in combination with the ANB instruction, pay attention to the range that will be inverted.
For details of the ANB instruction, refer to Page 131, Section 5.2.1
