    • An operating system which utilizes a multi-functional wall station for a motorized barrier includes an operator for controlling movement of a barrier between various positions. The operator may receive signals from a wireless or wired wall station transmitter, a wireless keyless entry device and/or a portable remote transmitter device. The multi-function wall station provides for selective concealment of certain switches or buttons which are not commonly used in the day-to-day operation of a wall station. For example, the up/down switch may be actuated by a hinged cover which conceals other selected operational buttons and wherein those operational buttons are only accessed upon opening of the hinged cover. The wall station also provides a periodic lighting element so as to easily direct the user to push the hinge cover to initiate up/down movement of the barrier. The multi-function wall station also provides for an operational selection wherein the door may be closed in a normal manner; by an auto-close feature, wherein the door closes after a predetermined period of time; or a RF block mode, wherein the station prevents transmission of any remote radio frequency signals to the operating system. The auto-close feature may only be enabled upon actuation of a keyless entry device so as to allow the user to re-enter the garage in the unfortunate circumstance of being locked out of the garage.
    • 利用用于电动屏障的多功能壁挂站的操作系统包括用于控制各个位置之间的屏障移动的操作者。 操作员可以从无线或有线墙壁发射机,无线无钥匙进入装置和/或便携式远程发射机装置接收信号。 多功能壁挂站提供选择性地隐藏在墙上电台的日常操作中不常用的某些开关或按钮。 例如,上/下开关可以由隐藏其它所选择的操作按钮的铰接盖来致动,并且其中那些操作按钮仅在铰接盖打开时被访问。 壁挂站还提供周期性的照明元件,以便容易地引导用户推动铰链盖以启动屏障的上/下移动。 多功能壁挂站还提供操作选择,其中门可以以正常的方式关闭; 通过自动关闭功能,其中门在预定时间段之后关闭; 或RF块模式,其中所述站阻止将任何远程射频信号传输到所述操作系统。 自动关闭功能只能在启动无钥匙进入装置时启用,以便允许用户在被锁定在车库之外的不幸环境中重新进入车库。

    • A method for ensuring data coherency in buffered direct memory access (DMA) data transfers. The DMA controller realizes the last piece of data is being transferred to the write buffer. The DMA controller then sends a “Last Write Data” signal to the external memory access arbitration unit. The external memory access arbitration unit then allows completion of all pending memory operations. If a memory request occurs, a wait line is asserted such that memory operations (i.e., reading from, or writing to, the memory) are prevented for all sources other than the DMA channel associated with the “Last Write Data” signal. The external memory access arbitration unit also grants priority to the DMA channel associated with the “Last Write Data” signal. This effectively flushes the write buffer and completes the buffered DMA data transfer. The external memory access arbitration unit then deasserts any asserted wait lines and memory operations are no longer prevented.
    • 一种用于确保缓冲直接存储器访问(DMA)数据传输中的数据一致性的方法。 DMA控制器实现将最后一条数据传输到写缓冲区。 DMA控制器然后将“最后写入数据”信号发送到外部存储器访问仲裁单元。 外部存储器访问仲裁单元然后允许完成所有待处理的存储器操作。 如果发生存储器请求,则等待线被断言,使得除了与“最后写入数据”信号相关联的DMA通道之外的所有源,防止存储器操作(即,从存储器读取或写入存储器)。 外部存储器访问仲裁单元还向与“最后写入数据”信号相关联的DMA通道优先。 这有效地刷新写入缓冲区并完成缓冲的DMA数据传输。 外部存储器访问仲裁单元然后解除所有被断言的等待行,并且不再阻止存储器操作。

    • The present invention provides a method for breakpoint stepping a multi-bus device. The multi-bus device includes a breakpoint unit capable of detecting bus events on multiple busses. The breakpoint unit is originally programmed to break on the detection of a specified bus event on a bus selected from multiple busses. After the specified bus event has been detected and the device has entered one of several possible frozen states, the breakpoint unit may be programmed to detect a new bus event on a bus selected from multiple busses. The method is repeated as needed to achieve breakpoint stepping, including single stepping.
    • 本发明提供了一种多总线装置的断点步进方法。 多总线装置包括能够检测多个总线上的总线事件的断点单元。 断点单元最初被编程为在从多个总线选择的总线上检测到指定的总线事件时中断。 在检测到指定的总线事件并且设备已经进入几个可能的冻结状态之一之后,断点单元可以被编程为在从多个总线上选择的总线上检测新的总线事件。 根据需要重复该方法以实现断点步进,包括单步执行。
