Note 12. All blocks are powered-up (PMVCM=PMADC=PMDAC=PMHPL=PMHPR=PMMO= “1”), and HP-Amp is no
output. 10mA (typ) at playback only (PMVCM=PMDAC=PMHPL=PMHPR=PMMO= “1”, PMADC= “0”).
Note 13. All digital input pins including clock pins (MCLK, BICK and LRCK) are held at DVDD or DVSS. PDN pin is
held at DVSS.
