'''Flags''' are single-bit values which may be either on / set / binary "1" or off / cleared / binary 0.
Most CPUs have a status [[Register#Status_Register|status register]] containing multiple flag bitsindicating current status; they may also have [[Register#Control_Registers|control registers]] which alter the operation of the CPU. Flags may also be maintained by software, or appear in IO device registers.
