1) If the XTAL1 pin is driven by a crystal, reaching a minimum amplitude (peak-to-peak) of 0.3 × VDDOSC3 is
sufficient.
Note: It is strongly recommended to measure the oscillation allowance (negative
resistance) in the final target system (layout) to determine the optimal parameters
for the oscillator operation. Refer to the limits specified by the crystal supplier.
