causing a host side to enter into a suspend mode wherein entering into the suspend mode includes suspending communications across the isolation barrier and disabling a host isolation transceiver at the host side;
responsive to entering the suspend mode, disabling a host isolation transceiver at the host side;
periodically enabling the host isolation transceiver and the isolation barrier to transmit a data signal from the host side to a peripheral side;
exiting the suspend mode; and
enabling the host isolation transceiver.
