R39: Serial Port Pad Control, 16,429 (0x402D)
The optional pull-up/pull-down resistors are nominally 250 kΩ. When enabled, these pull-up/pull-down resistors set the serial port
signals to a defined state when the signal source becomes three-state.

LRCLK pad pull-up/pull-down configuration.
Description
Controls the digital volume attenuation for right channel inputs from the right DAC. Each bit corresponds to a
0.375 dB step with slewing between settings. See Table 73 for a complete list of the volume settings.
