3.2 Case 2: Power up

Play audio content

Power up: TAS2563 has been programmed, and there is no changed needed for configuration

Use case: Power up device to play audio content

Status: DSP program memory and coefficient memory have been programmed. Assuming configuration 0 is the default tuning data.

Steps to playback:

  1. Feed the PLL clock. Audio stream may start any time after this step.

  2. [A/AB] Unmute; This code is not part of the binary file.

    • static int tas2563_mute(struct snd_soc_dai *dai, int mute)

Steps to sleep:

  1. [AB] mute and shutdown TAS2563; This code is not part of the binary file.

    • static int tas2563_mute(struct snd_soc_dai *dai, int mute)

  2. Turn off PLL Clock
