TPS92611-Q1: LED short to GND fault alarm question

Part Number: TPS92611-Q1

Tool/software:

Hi export,

When LED short to GND, fault will pull low.

Whether this short to GND detection function could be OK when EN is high and PWM is low? 

Or it's only OK while EN and PWM are both high?

Please help to check this  ASAP, Thanks a lot!
