NRF52840 / RESET pin = Input only?

[Mickael]

Hi there, 

one quick one:

when configured as SYSTEM RESET, Does P0.18 acts as an Input/Output? i.e. will be asserted Low by the NRF52840 while the MCU is in reset? 

Or is it configured as an input only? 

Thanks,

Mickael

 It will be a type of input. If you are resetting the chip with e.g. calling NVIC_SystemReset() or with a watchdog timeout, then the reset pin will remain high.

Thanks for confirming.
