Hi team,

We want to check if we set the control register to all 0, whether it's the same function as the reset? Thanks.

Frank,

Thanks for bringing this to E2E. Yes, setting all the control register bits to 0 is effectively resetting the device, but this is more of a manual method. Is there a reason the RESET pin cannot be used?

Regards,

Hi Eric,

Thanks for your confirmation. The customer wants to use the control pin to do the function which is always used and monitor. Thanks.
