    • A power management PC expansion card controller that includes power on reset circuitry to reset power management enable registers during a reset period, thereby ensuring that the PME registers correctly identify the power management capabilities of the controller. Once the PME registers are reset, an instruction may be provided to change the state of the registers from a default reset state to a state that supports advanced power management capabilities, for example wake-up functions. Additionally, the controller includes blocking circuitry to block conventional reset signals from resetting the power management and proprietary registers if the PME register is instructed to change states, thereby preserving the data contained in the power management and proprietary registers against future reset events. The controller of the present invention supports advanced power management specifications without requiring additional pinout arrangement or reassignment of pin functionality, so that the controller of the present invention can be implemented in current computer system without a the need for retooling or re-layout of system board circuitry and wiring diagrams.
    • 电源管理PC扩展卡控制器,包括上电复位电路以复位电源管理在复位期间启用寄存器,从而确保PME寄存器正确识别控制器的电源管理功能。 一旦PME寄存器被复位,可以提供指令来将寄存器的状态从默认复位状态改变为支持高级电源管理能力的状态,例如唤醒功能。 此外,如果指示PME寄存器改变状态,则控制器包括阻塞常规复位信号的复位信号,以复位电源管理和专有寄存器,由此保留电源管理和专有寄存器中包含的数据以防止未来复位事件。 本发明的控制器支持高级电源管理规范,而不需要额外的引脚排列或引脚功能的重新分配,使得本发明的控制器可以在当前的计算机系统中实现,而不需要对系统板进行改装或重新布局 电路和接线图。
