2.7 Sync Multiplexer (SMUX)

The Synchronization Multiplexer (SMUX) selects a set of sync signals from the input sources and

provides them to the scaler. It generates signals that are missing, depending on the capability. The

MCU can select the output sync signals between the input sources and the generated signals.
