1 Maximum power saving mode; Register 0x31FD, Bit 4.
2 Test conditions: 30 pF load, 2.0 MHz frequency, 3.3 V AVDD.
3 Powering down the MIC_BIAS powers down all port MIC_BIAS pins. This disables all microphone bias circuits set to 100% or 50%, setting them to the high-Z state. The
0 V and high-Z states remain unaffected by the MIC_BIAS power state.
