DEFAULT
SYSCLK Pre-divider. Clock source (MCLK or PLL output) will
be divided by this value to generate SYSCLK.
00 = Divide SYSCLK by 1
01 = Reserved
10 = Divide SYSCLK by 2
11 = Reserved
MCLK Invert
0 = Master clock not inverted
1 = Master clock inverted
Reserved - Do Not Change
ADC Sample Rate Divider
000 = SYSCLK / 1.0
001 = SYSCLK / 1.5
010 = SYSCLK / 2.0
011 = SYSCLK / 3.0
100 = SYSCLK / 4.0
101 = SYSCLK / 5.5
110 = SYSCLK / 6.0
111= Reserved

Audio Interface Master Mode Select
0 = Slave mode
1 = Master mode
Reserved - Do Not Change
ADCLRC Direction
(Forces ADCLRC clock to be output in slave mode)
0 = ADCLRC normal operation
1 = ADCLRC clock output enabled
ADCLRC Rate
ADCLRC clock output = BCLK / ADCLRC_RATE
Integer (LSB = 1)
Valid from 8..2047
