|
* If the PLL is on, the count in the loop divider (SYNR) register

|
* effectively multiplies up the PLL clock (PLLCLK) from the reference
|
|
* frequency by 2 x (SYNR+1). PLLCLK will not be below
|
|
* the minimum VCO frequency (fSCM).
|
|
*
|
|
* The REFDV register provides a finer granularity for the PLL multiplier
|
|
* steps.
|
|
* The count in the reference divider divides OSCCLK frequency by REFDV + 1.
|
|
*
|
|
* PLLCLK = 2 * OSCCLK * (SYNR + 1) / (REFDV + 1)
