*1) Only when power is supplied to all the power supplies, you can supply power to input pin up to 5.5V.

When the power is turned off, only supply the power up to 3.6V.

*2) Crystal for oscillator CI value: CI  150

The evaluation by the crystal supplier is recommended.

Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended

Operating Ranges limits may affect device reliability.
