NOTES:
1. In LF mode, the LFXT1 oscillator requires a watch crystal. A 5.1M
resistor from XOUT to VSS is recommended when VCC <
2.5 V. In XT1 mode, the LFXT1 and XT2 oscillators accept a ceramic resonator or crystal up to 4.15MHz at VCC ≥ 2.2 V. In XT1 mode,
the LFXT1 and XT2 oscillators accept a ceramic resonator or crystal up to 8MHz at VCC ≥ 2.8 V.
2. In LF mode, the LFXT1 oscillator requires a watch crystal. In XT1 mode, LFXT1 accepts a ceramic resonator or a crystal.
