resistors
Over time, the capacitor will discharge through R to the point where the SCR turns off, and this subsequently closes the transistor and the uC detects this to perform some action. When R = 100kohm, it takes about 6 minutes for the cap to discharge and all the other stuff in the micro to start. When R = 120kohm, the cap does not discharge at all.
