2. Operation range of INV instruction
When INV instruction is used in a complicated circuit containing ORB and ANB instructions, the operation
range of INV instruction is as shown in the figure below:
INV instruction inverts the operation result after LD, LDI, LDP or LDF instruction located before INV
instruction.
Accordingly, if INV instructions are used inside ORB and ANB instructions, blocks after LD, LDI, LDP or LDF
instruction seen from each INV instruction are regarded as the target of INV operation.
