Method for automatically detecting the clock frequency of a system clock pulse for the configuration of a peripheral device
摘要：
The present invention provides a method for automatic identification of the clock frequency of a system clock (15) for the configuration of a peripheral device (12), having the following steps: generation of a secondary clock (16) at a predetermined clock frequency; application of the system clock (15) and of the secondary clock (16) to a host (10); application of the system clock (15) and of the secondary clock (16) to the peripheral device (12); determination of the clock frequency of the system clock (15) in the peripheral device (12) by means of the secondary clock (16); and configuration of the peripheral device (12) using the determined system clock (15).
摘要（中）：

本发明提供了一种用于自动识别用于配置外围设备（12）的系统时钟（15）的时钟频率的方法，具有以下步骤：以预定时钟频率产生辅助时钟（16）; 将系统时钟（15）和辅助时钟（16）应用于主机（10）; 将系统时钟（15）和辅助时钟（16）应用于外围设备（12）; 通过辅助时钟（16）确定外围设备（12）中系统时钟（15）的时钟频率; 以及使用所确定的系统时钟（15）的外围设备（12）的配置。
