KNOTQ
Performs a bitwise logical NOT operation on the destination operand. Each bit in the destination is inverted (0 becomes 1, and 1 becomes 0).
The following table covers what the source and destinations can be:
| source | destination(s) |
|---|---|
| #I | r64 |
| #I | m8 |
DO NOT support LOCK
This instruction is only available when the processor is operating in 64-bit mode or compatibility mode.
The destination operand MUST be a 64-bit register or a 64-bit memory location. Attempting to use a smaller register size will result in an invalid operation. Since this instruction performs a unary operation, there is no source operand; providing an immediate or an additional register is NOT permitted.
