    • A wake up circuit for a computer system with a codec controller. The circuit provides a wakeup signal to the computer system when a codec detects an event that requires the system to become active. This signal is provided whether the communications link between the codecs and their controller is active or inactive. When the link is inactive, as indicated by the absence of a bit clock, a data signal on any of the codec input lines triggers the controller to send a power activation signal to the system and to initiate an activation of the codec link. If the link is already active, the general purpose input status change bit is transmitted to the controller, which writes it into a register that is used to trigger a power activation signal to the system. An enable input permits the wakeup signal to be enabled or disabled under program control. The wakeup signal can be used to trigger a system management interrupt or other interrupt suitable for initiating a system resume function.
    • 用于具有编解码器控制器的计算机系统的唤醒电路。 当编解码器检测到需要系统激活的事件时,该电路向计算机系统提供唤醒信号。 提供该信号是否编解码器与其控制器之间的通信链路是活动的还是非活动的。 当链路处于非活动状态时,如没有位时钟所示,任何编解码器输入线上的数据信号触发控制器向系统发送电源激活信号并启动编解码器链路的激活。 如果链路已经处于活动状态,则通用输入状态改变位被发送到控制器,控制器将其写入用于触发系统功率激活信号的寄存器。 启用输入允许在程序控制下启用或禁用唤醒信号。 唤醒信号可用于触发适用于启动系统恢复功能的系统管理中断或其他中断。
