Method for automatically detecting the clock frequency of a system clock pulse for the configuration of a peripheral device

A method of identifying a clock frequency of a system clock for the configuration of a peripheral device, the method comprising:

• a) providing a secondary clock at a predetermined clock frequency;
• b) applying the system clock and the secondary clock to a host;
• c) applying the system clock and the secondary clock to the peripheral device;
• d) determining the clock frequency of the system clock in the peripheral device using the second clock and based on the predetermined clock frequency;
• and
• e) configuring the peripheral device using the determined system clock.

• d) determining the clock frequency of the system clock in the peripheral device using the second clock based on the predetermined clock frequency;
• and
• e) setting an identical interface transmission rate for a first interface of the host and for a second interface of the peripheral device as a function of the clock frequency of the determined system clock.
