Register Definitions
PMVCM: Power Management for VCOM Block
PMADC: Power Management for IPGA and ADC Blocks
PMDAC: Power Management for DAC Blocks
PMHPL: Power Management for Lch of Headphone Amp
PMHPR: Power Management for Rch of Headphone Amp
PMMO: Power Management for Mono Output
HPLMT: Mute for Lch of Headphone Amp
HPLMT: Mute for Rch of Headphone Amp
All blocks can be powered-down by setting the PDN pin to “L” regardless of register values setup. In this case, all
control register values are initialized.

0: Power OFF (Default)
1: Power ON
0: Power OFF (Default)
1: Power ON
MCLK should be present when PMADC bit= “1”.
0: Power OFF (Default)
1: Power ON
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 HVSS(0V).
1: Power ON
0: Power OFF (Default). HPR pin becomes HVSS(0V).
1: Power ON
0: Power OFF (Default) MOUT pin becomes Hi-Z.
1: Power ON
0: Normal operation (Default). MUTET pin is connected to VCOM pin internally.
1: Mute. MUTET pin is connected to HPL pin internally.
0: Normal operation (Default). MUTET pin is connected to VCOM pin internally.
1: Mute. MUTET pin is connected to HPR pin internally.
