In order to minimize the power dissipation, all unused digital inputs pins should be tied inactive to VDD or

Vss and all unused I/O pins should be tied inactive through a 10KΩ resistor to VDD or Vss. All port A input

pins and bydirectional pins must have a valid state at all time when port A is released in order to minimize

power; those pins must then be pulled up or down or driven by another device.

When the codec is not used, VDDA should be connected to VDD and VssA to Vss, and all codec pins should

be left floating except Vref which should still be decoupled.
