Assembler:Commands:NOT

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

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.
