Register 46h Line 1 DAC/ADC Level
Reset setting for Line 1 device = 0x8080
Reset setting for Line 2 device = 0x0000
This read/write register controls the modem AFE DAC and ADC levels. The default value after cold register reset
for this register (8080h) corresponds to 0 dB DAC attenuation with mute on and 0 dB ADC gain with mute on.
