The device supports a low-frequency crystal (32.768 kHz) on the LFXT pins and a high-frequency crystal on the HFXT pins. External bypass capacitors for the crystal oscillator pins are required.
It is also possible to apply digital clock signals to the LFXIN and HFXIN input pins that meet the specifications of the respective oscillator if the appropriate LFXTBYPASS or HFXTBYPASS mode is selected. In this case, the associated LFXOUT and HFXOUT pins can be used for other purposes.
Figure 7-2 shows a typical connection diagram.
