17.8
The USB module has specific clock requirements. For
full-speed operation, the clock source must be 48 MHz.
Even so, the microcontroller core and other peripherals
are not required to run at that clock speed or even from
the same clock source. Available clocking options are
described in detail in Section 2.3 “Oscillator Settings
for USB”.
