NRF52840 / pin state during RESET

[Mickael]

Hi there,

I am looking to double check the state of NRF52840 while its reset is active. 

I have found this thread regarding the NRF52832  (https://devzone.nordicsemi.com/f/nordic-q-a/18421/nrf52832-uart-pin-state-in-reset ) stating that:

When you hold the chip in reset mode the GPIO pins will be configured as PIN_CNF[pin number] = 0x02, which means:

• Input pin
• Disconnected input buffer
• No Pull
• S0S1 drive
• Sense Disabled

But I thought it was wise to check this applies to the big brother too! 

Thanks for your help,

Mickael

Hello,

Yes. This applies to big brother too.

You can see in the table for "reset behavior" on infocenter that the GPIOs are reset on every type of reset except for wakeup from system off.
