DRV8305-Q1: question about UVLO function

hi expert

For ULVO function in datasheet, i have two questions

Q1: How can i understand the parameter of PVDD falling and PVDD rising?

Let us assume PVDD is 10V now, when PVDD is rising to 42.5V(10V+32.5V( shown in datasheet)) because of load ramp or supply pumping conditions, than nFAULT pin will show an error?

Q2: what the value of overvoltage for DRV8305-Q1?
