* target 180 MHz, source 16 MHz -> ratio = 11.25 = 22.5 x 2 = 45 x 4

|

|

|
|
|
* so we double again to choose a multiplier of 90, and a divider of 8
|
|

|
|
|
|
* 50 <= PLLN <= 432 (50-99 only if VCO input > 1 MHz)
|
|
|

* PLL output clock frequency = VCO frequency / PLLP,
|
|
|
|
|
* PLLP = 2, 4, 6, or 8
|
|
|
|
|
* USB OTG FS clock frequency = VCO frequency / PLLQ,
