Abstract
An apparatus and method is disclosed for avoiding metastability problems during a data transfer between a first circuit operating at first clock frequency and a second circuit operating at a second clock frequency. The first circuit sends an asynchronous control signal to the second circuit. The second circuit samples the asynchronous control signal at least two times and uses at least two samples of the asynchronous control signal to synchronize communication between the first and second circuits. The data is transferred between the first and second circuits when the circuits are synchronized. The second circuit indicates to the first circuit when the data transfer has been completed.
