1 This parameter is meant for those who do not use quartz crystals or resonators, but CAN osc, in crystal mode. In that case,

Vextal – Vxtal - 400mV criteria has to be met for oscillator’s comparator to produce output clock.

2 This parameter is meant for those who do not use quartz crystals or resonators, but signal generator clock to drive, in bypass

mode. In that case, drive only the EXTAL pin not connecting anything to other pin for the oscillator’s comparator to produce

output clock.

3 This parameter is meant for those who do not use quartz crystals or resonators, but CAN osc, in crystal mode. In that case,

drive one of the XTAL_IN or XTAL_OUT pins not connecting anything to other pin for the oscillator’s comparator to produce

output clock.

4 This parameter is meant for those who do not use quartz crystals or resonators, but signal generator clock to drive, in bypass

mode. In that case, drive only the xtal_in pin not connecting anything to other pin for the oscillator’s comparator to produce

output clock.

5 Leakage current is measured with output drivers disabled and pull-up/pull-downs inactive.

6 Pullup current is measured at VIL and pulldown current is measured at VIH.
