摘要： A standby control circuit for an integrated circuit module includes a first control circuit that is responsive, in a normal operating mode of the integrated circuit module, to an asynchronous standby signal indicating a standby mode entry event to output a standby mode signal synchronous with a primary clock signal to indicate a standby operating mode of the integrated circuit module. The standby control circuit also includes a second control circuit which is responsive, in a reduced power mode of the integrated circuit module, to the asynchronous standby signal indicating the standby mode entry event to control the first control circuit to output the standby mode signal synchronous with a secondary clock signal to indicate the standby operating mode.
