Slow clock enable. Used for both the jack insert
detect debounce circuit and the zero cross timeout.
0 = slow clock disabled
1 = slow clock enabled
Slow Clock Selection (Used for volume update
timeouts and for jack detect debounce)
0 = SYSCLK / 2^21 (Slower Response)
1 = SYSCLK / 2^19 (Faster Response)
Selects source for SYSCLK to CODEC
0 = MCLK pin
1 = FLL
Selects MCLK division in slave (MCLK input) mode:
0 = divide MCLK by 1
1 = divide MCLK by 2
Sets BCLK rate for Master mode
