    HREADY signal is used for both cases:

    to notify the master that slave is ready to transfer data (HREADY is high);

    to notify the master that transfer is completed (HREADY is high).

    When HREADY is low - the transfer is extended (wait state is added).

    The Master also samples HRESP (from slave) for OKAY or ERROR transfers.
