Note 23. PLL Master Mode (MCKI =13.5MHz, FS3-0 bits = “1011”)で、PMADL = PMADR = PMDAC = PMPFIL =
PMLO = PMSPK = PMPLL = MCKO = PMBP = PMMP = PMMICL= PMMICR = M/S = PMV bits = “1”,
SPK-amp No load、LIN/RIN, BEEP pinへの入力信号は無入力、VIN pin への入力信号が黒信号入力、
LOUT/ROUT pin 無出力、SDTI pin は“0”データ入力の場合です。このとき、MPWR pinの出力電流は
0mAです。パスの設定は、BRDAC= ADCPF = PFSDO bits = “1”, PFDAC = “0”, DACS = DACL bits = “1”,
BEEPS = BEEPL bits = “0”です。MG2-0 bits = “000”, HPF = LPF = FIL3 = EQ0 = EQ1~5 = ALC1~2 bits =
“0”, MONO1-0 bits = “00”, DVOL7-0 bits = “C0H”, SMUTE bit = “0”です。
Note 24. EXT Slave Mode (PMPLL=M/S=MCKO bits = “0”), PMADL = PMADR = PMMICL= PMMICR = bits = “1”
LIN/RIN pinへの入力信号は無入力の場合です。パスの設定は、ADCPF = PFSDO bits = “0”です。
Note 25. EXT Slave Mode (PMPLL=M/S=MCKO bits = “0”)、PMDAC= PMLO bits =“1”, SDTI pin は“0”データ入
力、LOUT/ROUT pin 無出力の場合です。パスの設定は、BRDAC =PFDAC bits = “0”, DACL bit = “1”,
DACS =BEEPS =BEEPL bits = “0”です。 MONO1-0 bits = “00”, DVOL7-0 bits = “C0H”, SMUTE bit = “0”
です。
Note 26. EXT Slave Mode (PMPLL=M/S=MCKO bits = “0”)、PMDAC = PMSPK =SPPSN bits = “1”, SDTI pin は“0”
データ入力、SPK-amp No loadの場合です。パスの設定は、PFDAC bit = “0” DACS bit = “1”, DACL
=BEEPS =BEEPL bits = “0”です。 MONO1-0 bits = “00”, DVOL7-0 bits = “C0H”, SMUTE bit = “0”です。
Note 27. PMV bit = “1”, 無負荷時でVIN pin への入力信号が黒信号入力の場合です。
Note 28. ディジタル入力ピン(MCKI, LRCK, BICK, SDTI, CSN/SDA, CCLK/SCL, CDTIO/CAD0, I2C pins)を
TVDD(AK4958EG), DTVDD(AK4958ECB)またはVSS2にI2C pinをAVDDまたはVSSに固定した時の値
です。
