INT/EXT: Select Internal / External MIC (Refer to Figure 12 and Figure 13.)
0: Internal MIC (RESET)
1: External MIC
INT/EXT bit and INT_EXT_DET pin are ORed.
When this function is controlled by INT_EXT_DET pin, INT_EXT bit is fixed to “0”. When this
function is controlled by INT/EXT bit, INT_EXT_DET pin is fixed to “L”.
HPF: Select HPF-Amplifier
0: Disable (RESET)
1: Enable
When HPF bit is “0”, HPF-Amp becomes a unity gain buffer.
When External MIC (INT/EXT bit = “1” or INT_EXT_DEC pin = “H”) is selected, HPF bit is
ignored.
AIN: Select input signal of ALC1 and change gain table of IPGA.
0: MIC (RESET)
1: LINE
AOUT1-0: Select input signal of LINEOUT or Analog Volume (OPGA)
ON/OFF of DAC is selected by AOUT0 bit and ON/OFF of Analog Through Mode is selected by
AOUT1.
00: Input signal is OFF. Common voltage is output.
01:DAC (RESET)
10: Analog Through Mode (Output signal of ALC1)
11: Output signal of DAC and Analog Through are mixed.
ADMIX: Output signal of ALC1 and input signal of SHT pin are mixed.
0: Disable (RESET)
1: Enable
