Hi Sir,
The datasheet says it's okay with VDD-VIO >=0. If VDD is fixed 5V and VIO is dynamic changing, e.g. 3.5V~4.2V, is it still okay? Thanks for advice.

How fast is VIO changing?
Keep in mind that VIH and VIL are 80% and 20% of VIO respectively. This affects all digital IO levels: SPI, INTB, TBCLK.
Thanks,
