Hi Team,

We would like to know the set timing of “PWR_OFF_SEQ=1”.

We guess that the timing is after “NRESPWRON” and "NRESPWRON2" become HIGH.

Is my understanding correct?

If no, could you please let us know the suitable timing?

Regards,

Hi, Hide,

Yes, the timing to set “PWR_OFF_SEQ=1” should be “NRESPWRON” and "NRESPWRON2" becoming "HIGH" and before the switch-off sequence starts.

Hi Phil-san,

I have one more question.

we would like to set this resister early.

Can I set “PWR_OFF_SEQ=1” before “NRESPWRON” and "NRESPWRON2" become HIGH.

(Please refer to the following timing)

No, since the “NRESPWRON” and "NRESPWRON2" can reset is back to "0".
