    • A method performed in an electronic device that connects via a USB connector to an accessory that supports multiple different operating modes. The method comprises: in response to successful authentication of the accessory after an initial connection, configuring an accessory usage setting of the electronic device to correspond to the accessory's default operational mode. In response to a request to change the operational mode of the accessory to a second operational mode: communicating to the accessory, over the signal/communication lines of the USB, mode identifying information corresponding to the second operational mode; generating a voltage level change on an ID line of the USB connector to communicate to the accessory that a change in the accessory's present operational mode is being triggered, where the accessory is designed to change to the second operational mode when a pulse or voltage level change is detected on the ID line.
    • 一种在经由USB连接器连接到支持多种不同操作模式的附件的电子设备中执行的方法。 该方法包括:响应于在初始连接之后对附件的成功认证,配置电子设备的附件使用设置以对应于附件的默认操作模式。 响应于将附件的操作模式改变为第二操作模式的请求:通过USB的信号/通信线路与附件通信,对应于第二操作模式的模式识别信息; 在USB连接器的ID线上产生电压电平变化,以向附件通信正在触发附件的当前操作模式的改变,其中当脉冲或电压电平改变时,附件被设计为改变为第二操作模式 在ID行上检测到。

    • A mobile radiotelephone (120) includes a microcomputer (220), speakerphone control circuitry (106) and mobile radio (112). Mobile radio (112) includes a transmitter (242), receiver (244) and a duplexer (243) for coupling the transmitter (242) and receiver (243) to the mobile antenna. In the transmit voice path, speakerphone control circuitry (106) includes switch (201), variable gain amplifier (202), compressor amplifier (203), switch (204), variable gain amplifier (205), and two registers (212-213). In the receive voice path, speakerphone control circuitry (106) includes variable gain amplifier (232), expander amplifier (233), switch (234), variable gain amplifier (235), switch (236) and two registers (216-217). Speakerphone control circuitry (106) also includes rectifier/filter (224), a companding analog-to-digital (A/D) converter (225), two latches (218-219), rectifier/filter (226) and two registers (214-215). Microcomputer (220) accesses registers (212-217) by means of a data bus (222) including address, control and data lines. Microcomputer (220) utilizes digital samples from A/D converter (225) to continuously generate and store in its memory an envelope signal and a valley signal for the transmit and receive voice paths. In order to determine when to switch gain between the voice paths, microcomputer (220) compares the envelope signal to the valley signal to detect the presence of voice signals and, if the voice signals are detected for a pre-selected time, the gain of the path in which voice signals have been detected is increased and the gain of the other path is decreased.
