PMADAR: MIC-AmpA Rch and ADCA Rch Power Management
PMVCM: VCOM Power Management
Each block can be powered-down respectively by writing “0” in each bit of this address. When the PDN pin is “L”, all
blocks are powered-down regardless as setting of this address. In this case, register is initialized to the default value.
When PMVCM, PMADAL, PMADAR, PMADBL, PMADBR, PMPLL, PMPLL, PMMPA,PMMPB and MCKO bits
are “0”, all blocks are powered-down. The register values remain unchanged.
When the all ADC is powered-down, external clocks may not be present. When one of the ADC is powered -up,
external clocks must always be present.
