Power Management 1
When any blocks are powered-up, the PMVCM bit must be set to “1”. PMVCM bit can be set to “0” only
when all power management bits of 00H and 01H, PMPLL and MCKO bits are “0”.
When the PMADC1 or PMADC2 bit is changed from “0” to “1”, the initialization cycle (1059/fs=22.1ms
@48kHz) starts. After initializing, digital data of the ADC is output.
