6.4.1 Active Mode

The device wakes up in active mode when AVDD and IOVDD are available. MD0 pin sets the type of audio serial interface and should be configured along with the supplies. Further, configure all other hardware control mode pins (MD1, MD2, MD3, MD4,MD5 and MD6) for the desired mode of operation before enabling the clocks for the device.

In active mode, when the audio clocks are available, the device automatically powers up the DAC channels and starts transmitting and playing data over the audio serial interface as per the configurations. If the clocks are stopped, then the device auto powers down the DAC channels.

Stopping the clocks or clock-error triggers an interrupt on the GPO pin. This is a latched interrupt that can be cleared by power-cycling the device supplies.
