PMMIN or PMAINL3 bit should be set to “1” for playback.
PMVCM: VCOM Power Management
0: Power-down (Default)
1: Power-up
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, 01H, 02H, 10H, 20H and MCKO bits are “0”.
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 all power management bits are “0” in the 00H, 01H, 02H and 20H addresses and MCKO bit is “0”, all blocks are
powered-down. The register values remain unchanged.
When DAC is not used, external clocks may not be present. When DAC is used, external clocks must always be
present.
