CLKSRC
Clock source select.
0 = direct from MCLK pin (default).
1 = PLL clock.
[2:1]
INFREQ[1:0]
Input clock frequency. Sets the core clock rate that generates the core clock. If the PLL is used, this value is
automatically set to 1024 × fS.

COREN
Core clock enable. Only the R0 and R1 registers can be accessed when this bit is set to 0 (core clock disabled).
0 = core clock disabled (default).
1 = core clock enabled.
