1 = Input enabled for I2S Secondary Audio
0 = Input disabled for Secondary Audio
Swap Left and Right Samples of Aux Audio Output.
0 = Left sample first in frame
1 = Right sample first in frame
MCLK master
0 = MCLK is an input
1 = MCLK is an output (not recommended in Aux Audio Mode
since 24/12MHz rates cant be supported and 112MHz internal
clock is imprecise but is useful for testing.)
MCLK rate
000 = 24MHz (HDA BitClk)
001 = 12MHz (HDA BitClk/2)
010 = 22.5792MHz
011 = 11.2896MHZ
100 = 5.6448MHZ
101 = 28.224MHz
110 = 14.112MHz
111 = 7.056MHz
Writing causes registers to revert to their default values (similar
to a function group reset)
BTL (port D) is forced on in Aux Audio Mode
DMIC powered down in Aux Audio Mode (including DAC)

MCLK Output Enabler
0 = MCLK Output is disabled in master mode
1 = MCLK is an output in master mode (input in slave mode))
