PMDAC: Power Management for DAC Blocks
0: Power OFF (Default)
1: Power ON
When PMDAC bit is changed from “0” to “1”, DAC is powered-up with the current register values (ATT
value, sampling rate, etc).
PMHP: Power Management for Headphone Amp
0: Power OFF (Default). HPL/HPR pins become HVSS (0V).
1: Power ON
PMCP: Power Management for Charge Pump Circuit
0: Power OFF (Default)
1: Power ON
PMLO: Power Management for Line-out Amp
0: Power OFF (Default). LOUT/ROUT pins become HVSS (0V).
1: Power ON
PMAUX: Power Management for Aux Out
0: Power OFF (Default) LAUX and RAUAX pins become AVSS (0V).
1: Power ON
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.
