Abstract
The present invention provides a device for handling requests for changing system mode. The device includes a signal hold/clear unit and a gate control unit. The signal hold/clear unit has the first input receiving a request signal, the second input receiving a control signal, and an output holding the request signal. Wherein, the signal hold/clear unit clears the request signal being held while the control signal is active. The gate control unit has the first input connected to the first input of the signal hold/clear unit, the second input connected to the output of the signal hold/clear unit, the third input connected to the second input of the signal hold/clear unit, and an output. Wherein, the gate control unit passes the request signal while the control signal is active, otherwise blocks the request signal.
