This section explains how the module selects and enables its inputs, manages its own power state, starts up, keeps its settings, shares its DSP bus with a SigmaStudio programmer, and works alongside other modules.

• Inputs and the enable mask

  ---

  The six sources, selecting one, and the enable mask the encoder follows.

• Volume and encoder

  ---

  The encoder's turn and press, the volumes, mute, clip and fault reporting.

• Automatic power-down

  ---

  Powering down after silence: the delay, the threshold, the target level and the wake on audio.

• 12 V trigger

  ---

  The 12 V trigger input of PCB 1.4: follow mode, push-button mode and priority.

• Start-up and the safe state

  ---

  What happens at power-up, the factory record, and the safe state of an unsupported board.

• SigmaStudio programmer coexistence

  ---

  Using a SigmaStudio USBi on a running module: what the firmware does while it is attached.

• Settings and memory

  ---

  What the module remembers, when it writes it, the reset to the defaults, and what an update does with it.

• Several modules together

  ---

  Audio over I2S or the network, two modules over Bluetooth, and the control of each module.
