53.6.4 32.768 kHz Crystal Oscillator

PIC32CM LE00/LS00/LS60 32.768 kHz crystal oscillator is optimized for very low-power consumption, hence close attention must be made when selecting crystals.

Figure 53-9. 32.768 kHz Crystal Oscillator Schematics
Note: 32.768 kHz crystal selection must be done using both the crystal data sheet and the crystal oscillator parameters given in the XOSC32K Electrical Specifications from the Electrical Characteristics chapter.
