Simulation data
Covers the start-up time of the PLL and of its dedicated voltage regulator.
Only 24 or 48 MHz input frequencies are authorized to support USB-related features and in particular those of the bootloader program in ROM.
For optimal settings of UPLL, set the PMC_PLL_ACR as follows:

PMC_PLL_ACR=0x12023010 for f_IN=[20 MHz, 32 MHz]

PMC_PLL_ACR=0x1B023010 for f_IN=[32 MHz, 50 MHz]
The post divider is hardwired in a divide-by-2 configuration.
