DRV8305: nFAULT at startup of DRV8305

Part Number: DRV8305

Dear, All

Customers are evaluating using DRV8305.
A phenomenon occurred in which pulses of the nFAULT signal continued to be output while EN_GATE was turned on after the supply voltage was determined.
When the status register was read, the nFAULT signal was not output, but the error flag bit was not turned on at all in the status register.
I want to know if this is a specification at startup.

Thanks, Masami M.
