If the link status indicates that the link training is successful, a link is established between the source device and the sink device, or if the link status indicates that the link training is unsuccessful, a different set of preset parameters is loaded and link training is then performed again. The steps of loading, performing and reading are repeated with each of the plurality of sets of preset parameters until the link status indicates that the link training is successful.
