GPIO1 Internal pull-down enable:
0 = Internal pull-down disabled
1 = Internal pull-down enabled
GPIO1 Polarity invert
0=Non inverted
1=Inverted
CSB/GPIO1 pin function select:
000= input (CSB/jack detection: depending on
MODE setting)
001= reserved
010=Temp ok
011=Amute active
100=PLL clk o/p
101=PLL lock
110=logic 1
111=logic 0
Reserved. Initialise to 00
Jack Detection Enable
0=disabled
1=enabled
Pin selected as jack detection input
00 = GPIO1
01 = GPIO2
10 = GPIO3

Reserved. Initialise to 0
Reserved. Initialise to 0
Softmute enable:
0=Disabled
1=Enabled
Reserved. Initialise to 0
DAC oversample rate select
0 = 64x (lowest power)
1 = 128x (best SNR)
Automute enable
0 = Amute disabled
1 = Amute enabled
Right DAC output polarity:
0 = non-inverted
1 = inverted (180 degrees phase shift)
Left DAC output polarity:
0 = non-inverted
1 = inverted (180 degrees phase shift)
DAC left and DAC right volume do not update
until a 1 is written to DACVU (in reg 11 or 12)
