Hi team,

I would like to Reset the device completely when error occurs.

Could you advise if internal registers are reset during power-down mode(PD=0)?

Or do we need to stop power supply or send reset command through SPI to reset the internal register?

regards,

Hello,

On power up or after reset it is required to program Mode Control Register and Program Register to required mode of operation

Powering the device should reset the configuration registers

Hi Cynthia-san,

Thank you for you answer.

Does /PD = Low also reset the whole device and registers?

I would especially would like to know if the /PD pin can be used as a reset pin.

Yes, that is what i would conclude from the datasheet.
