Abstract
An electronic circuit includes transmit-side circuitry and receive-side circuitry. The transmit-side circuitry belongs to a first domain of the circuit and is configured to transmit a data signal from the first domain to a second domain of the circuit. The receive-side circuitry belongs to the second domain and is configured to receive the transmitted data signal. The receive-side circuitry is configured to transfer to the transmit-side circuitry a read pointer value indicative of a readout position in a buffer memory that buffers the data signal, and to retain the read pointer value in a non-volatile element that is accessible to the transmit-side circuitry.
