    • A wake-up system is provided to allow host computer access to a Card Information Structure (CIS) on a PCMCIA card during a SLEEP mode. The CIS is stored in a non-volatile memory accessible to a host computer via a PCMCIA bus and to PCMCIA card logic via a local bus. Arbitration logic is coupled between the PCMCIA and local buses to control access to the memory. Sleep logic prevents a fast clock signal from being supplied to the arbitration logic and the PCMCIA card logic when the PCMCIA card is switched into the SLEEP mode. A CIS read detect circuit decodes a CIS read operation on the PCMCIA bus and asserts the CIS detect signal supplied to the sleep logic. In response, the sleep logic allows the fast clock signals to be supplied to the arbitration logic and adapter card subsystem to exit from the SLEEP mode and provide the host computer with access to the memory storing the CIS information.
    • 提供唤醒系统,以允许主机在休眠模式下访问PCMCIA卡上的卡信息结构(CIS)。 CIS存储在主机通过PCMCIA总线可访问的非易失性存储器中,并通过本地总线存储到PCMCIA卡逻辑。 仲裁逻辑耦合在PCMCIA和本地总线之间,以控制对存储器的访问。 当PCMCIA卡切换到休眠模式时,休眠逻辑可防止将快速时钟信号提供给仲裁逻辑和PCMCIA卡逻辑。 CIS读取检测电路解码PCMCIA总线上的CIS读取操作,并断言提供给睡眠逻辑的CIS检测信号。 作为响应,睡眠逻辑允许将快速时钟信号提供给仲裁逻辑和适配器卡子系统以退出休眠模式,并向主机提供对存储CIS信息的存储器的访问。
