Description: A switch flag, which set the radio region calibrate listen mode as enable or disable, tells whether the listen unauthentic neighbor while calibrating is supported. Because listen unauthentic neighbor will need added time, so it as a option. enable means it listens unauthentic neighbor while calibrating, disable means it would not listen unauthentic neighbor, In this case, we can't get unauthentic neighbor information after calibrate done. Notes the setting of radio region calibrate listen mode must have the corresponding setting of the golbal calibrate startup mode, and the golbal calibrate startup mode can't be cancel-periodic.
