How do I soft reset the NRF52?
So Im using Adafruit core for NRF52 based board. I wanted to soft reset the board, i.e. reset via code, how do I do that?

Apologies if it was asked before, I googled and couldn't find the answer :confused:

#include <Adafruit_TinyUSB.h> // Include the TinyUSB library
#include <nrf.h>              // Include the Nordic headers

void setup() {
  // Initialize Serial for debugging
  Serial.begin(115200);
  while (!Serial) {
    delay(10); // Wait for the Serial monitor to open
  }

  Serial.println("Board will reset in 3 seconds...");
  delay(3000); // Wait for 3 seconds

  // Trigger a system reset
  NVIC_SystemReset();
}

void loop() {
  // Your main code here
}
