Note 18. When PMADL=PMADR=PMDAC=PMPFIL =PMLO=PMSPK=PMPLL=MCKO=PMBP=PMMP=M/S=
PMV bits = “1”, SPK-amp No load, and black signal is only input to the VIN pin in PLL Master Mode
(MCKI=12MHz). In this case, the output current of the MPWR pin is 0mA. AVDD=20.7mA (typ),
TVDD=1.5mA (typ).
Note 19. When PMADL = PMADR bits= “1” and PMPFIL bit = “1” in EXT Slave Mode (PMPLL=M/S=MCKO bits
=“0”).
Note 20. When PMDAC = PMLO bits= “1” and PMPFIL bit = “1” in EXT Slave Mode (PMPLL=M/S=MCKO bits
=“0”).
Note 21. When PMDAC = PMSPK =SPPSN bits = “1”, PMPFIL bit = “1”, and No load at SPK-amp in EXT Slave Mode
(PMPLL=M/S=MCKO bits =“0”).
Note 22. When PMV=PMCP bits = “1”, No-load, and the black signal is only input to the VIN pin.
Note 23. All digital input pins are fixed to TVDD or VSS2.
