command not operand
The NOT instruction implements the bitwise NOT operation. NOT operation reverses the bits in an operand. The operand could be either in a register or in the memory.
operand = !operand operand = ~operand
Example:
| operand: 0101 0011 | |------------------------------------| | After NOT -> operand: 1010 1100 |
Performs a bitwise NOT operation (each 1 is set to 0, and each 0 is set to 1) on the destination operand and stores the result in the destination operand location. The destination operand can be a register or a memory location.
Command Parameters[edit]
| Parameter | Description |
|---|---|
| operand | The operand to perform a bitwise operation on |
Examples[edit]
not al
not ax
not ax
not eax
not rax
not al
not ax
not ax
not eax
not rax
not [eax]
not [rax]
not [00123ABC]
not [SomeSymbol]
