nRF52832 reset input pin (P0.21)

[bsl_007]

Hi,
What does it mean that pin #24 / P0.21 (nRESET) is "Configurable as pin reset"?

Does P0.21 work as an input from an external reset circuit at power up?
Before anything has been configured by SW?

Hello,

I am letting you know that I have been assigned to this case. So far, I haven't had enough time to look into this. I will get back to you on Monday.

Kind Regards,

Hello,

Sorry for the long response time.

It means that the nRESET function can be exposed onto this pin. Please take a look at the pin reset documentation.

Kind Regards,

Thanks a lot - this is exactly what I was looking for!

One more question:
What is the status of all GPIOs during reset?
Are they set as inputs with or without a weak pull-up?

Hello,

I am glad to hear that my response was useful for you.

For your last question, I recommend you go through the product specification of nRF52832. In the P.S., you can find the behavior of GPIOs during different resets (refer to pages 85 and 86).

Kind Regards,

Abhijith
