Reset setting for Line 1 device = 0x0000
Reset setting for Line 2 device = 0x8080
This read/write register controls the modem AFE DAC and ADC levels. The default value after cold register reset
for this register (0x8080) corresponds to 0 db DAC attenuation with mute on and 0 db ADC gain with mute on.
Reset setting for Line 1 device = 0x003F
Reset setting for Line 2 device = 0xFC00
The GPIO Pin Configuration register is read/write for configuring Slot 12 I/O. These pins are digital commands
(virtual pins). This register specifies whether a GPIO pin is configured for input (1) or output (0). The digital
controller sends the desired GPIO pin value over output slot 12 in the outgoing stream of the AC-link before
configuring any of these bits for output.
