Register Definitions
PMVCM: Power Management for VCOM Block
PMDAC: Power Management for DAC Blocks
PMHPL: Power Management for Lch of Headphone Amp
PMHPR: Power Management for Rch of Headphone Amp
MUTEN: Headphone Amp Mute Control
PMMO: Power Management for Mono Output
All blocks can be powered-down by setting the PDN pin to “L” regardless of register values setup. All blocks can be
also powered-down by setting all bits of this address to “0”. In this case, control register values are maintained.

When PMDAC bit is changed from “0” to “1”, DAC is powered-up to the current register values (ATT
value, sampling rate, etc).
0: Power OFF (Default). HPL pin becomes VSS(0V).
1: Power ON
0: Power OFF (Default). HPR pin becomes VSS(0V).
1: Power ON
0: Mute (Default). HPL and HPR pins go to VSS(0V).
1: Normal operation. HPL and HPR pins go to 0.45 x VDD.
0: Power OFF (Default) MOUT pin becomes Hi-Z.
