我的配置如下
reg[ 1][ 51] = 0x40 ; Mic Bias enabled, Source = Avdd, 1.25V
reg[ 1][ 52] = 0x04 ; Route IN3L to LEFT_P with 10K input impedance //08=20k
reg[ 1][ 54] = 0x40 ; Route CM3L to LEFT_M with 10K input impedance //80=20k
reg[ 1][ 55] = 0x04 ; Route IN3R to RIGHT_P with 10K input impedance //08=20k
reg[ 1][ 57] = 0x40 ; Route CM3R to RIGHT_M with 10K input impedance //80=20k
reg[ 1][ 59] = 0x00 ; Enable MicPGA_L Gain Control, 0dB //0c=6db
reg[ 1][ 60] = 0x00 ; Enable MicPGA_R Gain Control, 0dB
reg[ 0][ 81] = 0xc0 ; Power up LADC/RADC
reg[ 0][ 82] = 0x00 ; Unmute LADC/RADC
