R/W

gain_ramp_rate

Controls the speed of the gain ramping when

ramping is activated

0 = nominal rate * 8

1 = nominal rate

2 = nominal rate / 8

3 = nominal rate / 16 (slowest)

The nominal rate (excluding headphone circuits) =

0.88 ms/dB. The nominal rate for the headphone

circuits is = 1.3 ms/dB.

R/W

pc_resync_auto

Program Counter resynchronisation control

0 = No resynchronisation. If the DAI drifts with

respect to the system clocks, either a sample is

skipped or it is double-sampled

1 = Automatic resynchronisation if the DAI drifts

with respect to the system clock

0x1

R/W

pc_freerun

Controls the filter operation when the DAI is not

enabled or when no DAI clocks are available on the

ADC to DAC processing path

0 = Filters are synchronised to the DAI

1 = Filters are free running
