During Front switching, in case of Front/Rear/SW continuously received, Rear and SW switching are the priority.
If you want the switching starts as the data transmission order, please transmit the next data after current switching is
ended.
■Transmission example 3
For Refresh data, the IC will internally judge that there is no difference with the current data setting and therefore gain
switching operation will not start.
Continuing the Refresh data and transmit the other block data.
