PMADL: ADC Lch Block Power Control
0: Power down (Default)
1: Power up
When the PMADL or PMADR bit changes from “0” to “1”, the initialization cycle (2081/fs=47.2ms
@44.1kHz) starts. After initializing, digital data of the ADC is output.

Even if PMBPM= “0”, the path is still connected between BEEPM and HP/SPK-Amp. BPMHP and BPMSP
bits should be set to “0” to disconnect these paths, respectively.
