Note 23. PMADL=PMADR=PMDAC=PMPFIL=PMDSP=PMLO=PMSPK=PMPLL=MCKO=PMBP=PMMP
=PMMICR =PMMICL =M/S =PMV =PMCP bits = “1”, SPK-amp No load, black signal is input to the VIN pin.
In this case, the output current of the MPWR pin is 0mA. The sampling frequency is 48kHz. 1kHz signal with
1.845Vpp amplitude is input to LIN and 1.2kHz signal with 1.845Vpp amplitude is input to RIN while the data
path setting is DSPBP=PFDAC=ADCDO bits = “1”. Noise canceling program is run by the DSP.
Note 24. In EXT Slave Mode (PMPLL=M/S=MCKO bits =“0”), PMADL = PMADR = PMMICL = PMMICLR bits =
“1”, and PMDSP bit = “0”.
Note 25. In EXT Slave Mode (PMPLL=M/S=MCKO bits =“0”), PMDAC = PMLO bits= “1”, and PMDSP bit = “0”.
Note 26. In EXT Slave Mode (PMPLL=M/S=MCKO bits =“0”), PMDAC = PMSPK =SPPSN bits = “1”, and PMDSP bit
=“0” with No load at the SPK-Amp.
Note 27. PMV =PMCP bits = “1”, No load, and the black signal is only input to the VIN pin.
Note 28. All digital input pins are fixed to TVDD or VSS2.
