5340 reset pin

[Allen_]

Hi：

 Can you reset the pin with an external MCU IO control, and if possible, how long the low potential lasts can reset 5340

Hi!

Yes, you can reset the nRF5340 by toggling the reset pin from an external MCU's GPIO.

and if possible, how long the low potential lasts can reset 5340

Just to confirm, are you asking what the minimum hold time is for the pin reset to trigger? I couldn't find any public documentation on this, but from what I could find, 1 us should be safe.

If I misunderstood that question, let me know!

Best regards,

Raoul

Thanks,

I want kowne minimum hold time is for the pin reset to trigger 

[Raoul]

I see. Then as mentioned, I believe 1 μs should be safe (but this might not be documented).

Best regards,
