Clock tree
1.
When the HSI is used as a PLL clock input, the maximum system clock frequency that can be achieved is
64 MHz.
2.
For the USB function to be available, both HSE and PLL must be enabled, with the CPU running at either
48 MHz or 72 MHz.
3.
To have an ADC conversion time of 1 s, APB2 must be at 14 MHz, 28 MHz or 56 MHz.
