System PLL Configuration
If RCWLR[DDRCM] and RCWLR[LBCM] are both cleared, the system
PLL VCO frequency = (CSB frequency) × (System PLL VCO Divider).
If either RCWLR[DDRCM] or RCWLR[LBCM] are set, the system PLL
VCO frequency = 2 × (CSB frequency) × (System PLL VCO Divider).
The VCO divider needs to be set properly so that the System PLL VCO
frequency is in the range of 400–800 MHz.
