Controls the source of the clock for all internal
operation:
0=MCLK
1=PLL output
Sets the scaling for either the MCLK or PLL
clock output (under control of CLKSEL)
000=divide by 1
001=divide by 1.5
010=divide by 2
011=divide by 3
100=divide by 4
101=divide by 6
110=divide by 8
111=divide by 12
Configures the BCLK output frequency, for use
when the chip is master over BCLK.
000=divide by 1 (BCLK=MCLK)
001=divide by 2 (BCLK=MCLK/2)
010=divide by 4
011=divide by 8
100=divide by 16
101=divide by 32
110=reserved
111=reserved
Reserved
Sets the chip to be master over LRC and BCLK
0=BCLK and LRC clock are inputs
1=BCLK and LRC clock are outputs generated
by the WM8978 (MASTER)
0 = low power mode enabled
1 = low power mode disabled
Controls clock division from SYSCLK to
generate suitable class D clock.
Recommended class D clock frequency =
1.4MHz.
