* SYNR register controls the multiplication factor of the PLL.
|
|
* 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)
