Clock switch arrangement for hot-plug function e.g. for modern personal computers, uses flip-flop groups for receiving interface interrupt signals as reaction to first and second clock signals

摘要

Correct change-over of asynchronous clocks operating at a large frequency difference can be achieved with an interface cable with a hot-plug function is interrupted or connected, with a first flip-flop group (43) receiving an interface interrupt signal as a reactive to the first clock signal. A second flip-flop group (45) receives the interface interrupt signal as a reaction to the second clock signal.
