6.4.7 Digital IO pins

TAS2320 supports 1.8V and 3.3V IO voltage supply based on the voltage applied on the IOVDD pin.

I2S digital input pin has an optional weak pull down to prevent the pin from floating. Pull downs are not enabled during HW shutdown. The pull downs are disabled by default and can be enabled by setting the corresponding Pull down enable bit high.
