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 ).
