nRESET

nRESET (pin 32) is a dedicated System on Chip (SoC) reset pin. An SoC reset is generated when the nRESET pin is pulled low and released. To ensure that the reset is issued correctly, the reset pin should be held low for a few microseconds.

The nRESET pin has a 13 kΩ internal pull-up resistor that is always on and connected to the nRF9160 internal voltage of 2.2 V. The nRESET pin can be connected to an external controller or mechanical switch that is controlled by the user. It is recommended to add a bypass capacitor and series resistor in the range of 1 kΩ to the nRESET routing close to the nRESET pin. For more information on pin reset, see Reset in nRF9160 Product Specification.
