DRV8303: Power-on of the DRV8303

I would like to ask about the power-on of the DRV8303.
Regarding the respective power-on timings for VDD_SPI, REF and PVDD1,
If VDD_SPI and REF are turned on first and PVDD1 is turned on after a delay,
does this cause any problems?
What problems may arise?
If there is anything we should be careful about in terms of power-on timing,
would you please tell us ?
