Description
Inverts each bit (0 or 1) of the 16-bit data specified by D.
This instruction is useful for controlling an external device (7−segment display) that uses negative logic
operation.
Flag conditions
・Error flag (R9008): Turns on for an instant when the area specified using the index modifier
exceeds the limit.
・Error flag (R9007): Turns on and stays on when the area specified using the index modifier
exceeds the limit.
