ADVANCE INFORMATION
PLL: Corrupted writes to CAL_IN field of PLL12_CAL_CTRL register
Writes to the PLL12_CAL_CTRL[11-0].CAL_IN field are corrupted, making CAL_IN unusable.
Use the PLL12 calibration in the NON-Bypassed mode (CAL_BYP = 0); in this case, the calibration is set based upon the PLL's own search rather than the PLL12_CAL_CTRL[11-0].CAL_IN register value. Also note that calibration should not be used unless DACEN = DSMEN = 0, which implies integer mode multiplication only.
