3.13 FMPLL electrical characteristics
The device provides a frequency-modulated phase-locked loop (FMPLL) module to generate a fast system
clock from the main oscillator driver.

2 _{PLLIN clock retrieved directly from FXOSC clock. Input characteristics are granted when oscillator is used in}
functional mode. When bypass mode is used, oscillator input clock should verify f_PLLIN and _PLLIN.
3 _{fCPU 64 MHz can be achieved only at temperatures up to TA = 105 °C with a maximum FM depth of 2%.}
