RESET
S0: Select Internal / External MIC (Refer to Figure 11 and Figure 12)
0: Internal MIC (RESET)
1: External MIC
S1: Select HPF-Amp
0: Disable (RESET)
1: Enable
When S1 bit is “0”, HPF-Amp becomes a unity gain buffer.
When External MIC (S0 bit = “1”) is selected, S1 bit is ignored.
S2: Select input signal of ALC and change gain table of IPGA.
0: MIC (RESET)
1: LINE
S4-3: Select input signal of LINEOUT or Analog Volume (OPGA)
ON/OFF of DAC is selected by S3 bit, and ON/OFF of Analog Through Mode is selected by S4
bit.
00: All input signals are OFF. Then output voltage becomes common voltage.
01:DAC (RESET)
10: Analog Through Mode (Output signal of ALC)
11: Output signal of DAC and Analog Through are mixed.
S6-5: Select gain of Pre-Amp; +12dB
