Hello Experts,

Let me confirm about CLR_FLTS. CLR_FLTS bit will be cleared automatically if customer set CLR_FLTS bit "1" even if fault register does not set(it means device has not been got any fault conditions), correct?

Hi Fujiwara-san

Yes, the customer can clear the fault using the SPI register CLR_FLTS.

When the fault condition is removed and CLR_FLTS is set to 1 then the latched fault will be cleared.

I'm confused when you mention the following:

Is the customer trying to set CLR_FLTS to 1 even if there is no fault?

Hi Yara-san,

Yes, customer would like to know what it will cause when CLR_FLTS bit set to "1" accidentally even if there is no fault.

Hi Fujiwara-san

CLR_FLTS will only be set to "1" if the user sets it to "1". I don't believe there is a scenario where a fault would cause CLR_FLTS to be set to 1.
