HPFAD: HPF after ADC Enable
0: Disable
1: Enable(Default)
When HPFAD bit = “0”, HPFAD block is through (0dB).
HPF: HPF Enable in Filter block that PMPFIL bit is controlled.
0: Disable
1: Enable(Default)
When HPF bit = “0”, HPF block is through (0dB).
EQ1: Equalizer1(EQ1) Enable
0: Disable (Default)
1: Enable
When EQ1 bit is “1”, the settings of EQA15-0, EQB15-0 and EQC15-0 bits are enabled. When EQ1 bit is “0”,
EQ1 block is through (0dB).
EQ2: Equalizer2(EQ2) Enable
0: Disable (Default)
1: Enable
When EQ2 bit is “1”, the settings of EQA15-0, EQB15-0 and EQC15-0 bits are enabled. When EQ2 bit is “0”,
EQ2 block is through (0dB).
SMUTE: soft mute control
0: Normal Operation (Default)
1: DAC outputs soft-muted
MDIF: MIC Input Type Select
0: Single-ended input (MIC pin Input: Default)
1: Full-differential input (MIC pin and BEEP/MICP pin Input)
When MDIF bit = “1”, it must be set PMBP bit = BEEPA bit = BEEPS bit = “0”.
DATT1-0: Output Digital Volume2; 6dB step, 4 Level (Table 22)
Default: “00H” (0.0dB)
